No, not much heat. Maybe a bit warmer. Very little. Tanning Bed is UVA/B, how hot do they get? With multiple bulbs??
How much UVB to give.

Weed needs UVB to do cellular damage/IE Change Chemical Profile. One just has to be careful and not fry them. Theres a fine line between being good, and frying. UVA doesnt do cellular damage to plants. It does to humans. 340nm is dangerous to humans.
For ME, Im only trying to reproduce the sun. The sun emits UVB, and plants have evolved with it. And you can believe weed did. Weed originated at high altitude where UVA/B is much higher. In Equador, UVA/B was measured as high as on MARS at 20,000 ft. Ya know the 1-10 scale the weather uses to measure the UV???? In Equador, it was measured at a 26. Even half of that will fry your butt. 13????
IMHO though not verified.. I feel the UVA/B increases the need for either more air flow, or a high amount of CO2. Logically I assume the bulbs, both UVA/B Increase Metabolism, so if you arent already getting an optimum amount of either, the plants may suffer, and make them grow slower, and decrease yield, and potency...... You HAVE to have good ventilation.
UVA makes the plant produce More Trichomes, but does not do cellular damage. Weed has a gene/protein thats activated at 280nm-285nm. Only bulb on the market I know of that has its most powerful spectrum from 280nm-300nm is a Solacure Flower power. The glass is super expensive. 32w Solacure is 20x more powerful than the best Reptile Bulb. Which is the Arcadia Desert Reptile 54w
UVA/B we speak of goes from 280nm-400nm, so the solacure UVB spectrum of strenght being from 280nm-300nm still leaves more UVA than UVB. Its balanced with a slight shift geared towards plants vs Animals/Reptiles ect.
5% of radiation that hits the earth is UVB. Plants get UVB in nature.
ALTITUDE
At higher altitudes, a thinner atmosphere absorbs less UV radiation. With every 1000 metres increase in altitude, UVA/B radiation levels increase by 10% to 12%.
Plants have a Protein that is most strongly activated at 280nm-285nm. Its just scientific fact.
UVR8 Protien
UV-B resistance 8 (UVR8) also known as ultraviolet-B receptor UVR8 is an UV-B – sensing protein found in plants and possibly other sources.[2] It is responsible for sensing ultraviolet light in the range 280-315 nm and initiating the plant stress response. It is most sensitive at 285nm, near the lower limit of UVB. UVR8 was first identified as a crucial mediator of a plant's response to UV-B in Arabidopsis thaliana containing a mutation in this protein. This plant was found to have a hypersensitivity to UV-B[3] which damages DNA. UVR8 is thought to be a unique photoreceptor as it doesn't contain a prosthetic chromophore but its light-sensing ability is intrinsic to the molecule.[4] Tryptophan (Trp) residue 285 has been suggested to act the UV-B sensor, while other Trp residues have been also seen to be involved (Trp233 > Trp337 > Trp94) although in-vivo data suggests that Trp285 and Trp233 are most important.[2]
Evolution
Although the complete genome sequence is only available from a limited number of angiosperms, bioinformatic analysis suggests that there are a large number of UVR8 orthologs. Both number and position of key residues seem to be well conserved among angiosperms but also other plant species (e.g., Chlamydomonas reinhardtii and Volvox carteri). The latter implies that UVR8 potentially appeared before the evolutionary split in vascular land plants which would be rational considering that at that time the amount of UV-B radiation that penetrated the earth surface was higher as the ozone layer was not fully developed, hence UV protection and acclimation would be of crucial importance.[5]
Structure
UVR8 is a β-propeller protein with 7 blade-shaped β-sheets. It shares sequence homology with mammalian proteins involved in regulating chromatin condensation, for example the human RCC1 gene product. In the dark state, UVR8 forms a homodimer that is localized in the cytosol, but UV-B illumination induces the dissociation of UVR8 dimer to its respective monomers and translocation to the nucleus occurs.[6] The dimer is held together via a complex salt bridge network.[2]
Mechanism
Upon UV-B irradiation, light is absorbed by one or more Trp residues which are situated adjacent to Arg residues which form salt bridges across the dimer interface. It is thought that this light absorption induces the disruption of the salt-bridges and thus leads to the molecule's monomerization.[2][7] Following monomerization, UVR8 accumulates in the nucleus where it interacts with a protein called constitutively photomorphogenic 1 (COP1). COP1 is known to act as an E3 Ubiquitin ligase that targets key transcription factors for ubiquitination and proteasome-mediated degradation. However, in the case of UVR8, it has been shown to act as a positive regulator of UVR8-mediated UV-B signalling.[8] Upon UV-B illumination, UVR8 interacts via a C-terminal 27 amino acid region with the WD40 domain of COP1 in the nucleus,[9] which triggers the induction of ELONGATED HYPOCOTYL 5 (HY5) — a key transcription factor for several UV-B responsive genes, and overall results in UV-B acclimation.[10]

ECUADORIAN CIVILIAN SPACE AGENCY PUBLISHES THE HYPERION REPORT:
ECUADOR, PERU AND COLOMBIA RECEIVING THE HIGHEST UV RADIATION DOSE ON THE PLANET
October 22 2008, Guayaquil - Ecuador: The Ecuadorian Civilian Space Agency - EXA published today the HYPERION Report, the results of a field study about the state of the ozone layer over equatorial latitudes, based on images from 10 different satellites and instruments from ESA, Environmental Canada, NASA, the KNMI, the DLR and 2 ground meteorological stations from EXA on Ecuadorian territory that proves the existence of a great weakening of the ozone layer over equatorial latitudes, resulting in extreme UV radiation hitting Ecuadorian territory, far exceeding the maximum tolerance or safety limit established for human health.
The radiation levels detected by the ground stations correlate perfectly with the satellite imaging and exceeds 14 UVI for the coastal city of Guayaquil and also exceeds 24 UVI for the capital city of Quito, the maximum tolerable level of radiation, as established by the UV Index of the World Health Organization (WHO) and the World Meteorological Organization (WMO) is 11 UVI. The study, that has taken 1 year to be completed found also that the power of the radiation is so high that even the normal could cover over this cities is unable to lower it down to acceptable human tolerance levels.
Although only Ecuadorian UV levels have been measured directly on the ground, satellite imaging indicates that Colombia and Peru are also being hit by extreme levels of UV radiation. The equipment used by EXA on this ground measurements is state of the art equipment, proven in Antarctic polar regions and in use be the University of Stanford and the Argentinean CONAE National Space Agency.
EXA announced too that starting today the HYPERION Reactive Alert Network starts operations as a public free service that will allow the population to know, in five minutes intervals, what is the radiation levels they are being exposed to and which actions they should take to avoid danger, recommendations based on the standard proposed by the WHO y WMO, EXA also urged publicly to the mobile phone companies present in the country to transmit this information to their customers in the form of a simple text message to get this information in real time to the inhabitants of the areas protected by the HYPERION Network.
This network covers the major cities of Quito an Guayaquil, protecting more than 4 million people by providing them with real time information vital to avoid exposure to harmful levels of radiation that in the mid term can lead to skin cancer, many types of blindness, a weakening of the immune system and therefore leaving them exposed to many illness.
EXA also revealed that the more powerful frequency of the UV radiation is in the range of 340 nm, a well known type of radiation that can alter human DNA, with the potential to cause cellular damage and mutations, this type of radiation reaches 14 watts per square meter in Quito, when normal levels should be in the range of 1 watt per square meter.
EXA directives made a call to the Ecuadorian government to urgently intervene to protect the population, due the fact that the HYPERION network can only protect 28% of the population, the 72% remaining is still left unprotected. they also said to be ready to support the effort and transfer the capabilities developed by them to the government, as EXA is an NGO with limited funding and this is a matter of national security that should be attended by the goverment.
The announced too that a copy of the HYPERION Report will be sent to the diplomatic representatives of the involved countries, but specially to Colombia and Peru, many recommendations were emitted as those like considering altering the schedule of the breaks in the schools to protect the children due to their high vulnerability, lift the actual restrictions for the use of anti solar films on the vehicles, the use of solar filters with an SPF over 70 for the coastal and Amazonia region and over SPF 100 for the Andean region and the call for the declaration of a National Climatic Emergency state.

I think the strips are 390or395nm, I’m aware there’s claims it don’t make the bud more potent. If it increase the trichs, smell stronger, look more colorful are all benefits for me. Atleast with some kind of experiments can know what they do, if they do anything at all

The Pjhillips says it peaks at 310nm-315nm, and purposefully avoid going lower than that. Phillips is made for treatment for Psoriosis., and does not go below 310nm.
Agromax either has a mistake on their website, or their false advertising by saying UVC starts at 290nm. Possibly trying to discourage the use of a bulb that goes to 280nm???? 280nm, is the turning point between UVC and UVB.
It also takes really expensive glass to let 280nm through, and as we know, UV doesnt reflect worth a crap. The Solacure has a Built In Reflector, specially made to reflect UVA/B most efficiently, and the bulb works with any standard fixture. Can also be run at 80w!!!!! vs 32w. Theyre way over built.
Agromax
UV-A light measures between 400-320nm, UV-B is between 320-290 and from 290-100nm is UV-C
Agromax doesnt go below 290nm. Also dont get me wrong, 290nm will probably give some kind of a response, but I also question the glass, and doesnt have a built in reflector, so it has to by way way less efficient at the least. And they use more electricity, and arent as powerful. Remember the SC can run at 80w. 2x more powerful than normal. But of course it wears the bulb out faster.
Solacure also makes Super Powerful UVA/b bulbs. WAY more powerful than the bulbs in mentioning. The are more like the sun as where the Flower Power is geared more to plants, this bulb also goes down to 280nm, but that is not its strongest frequency, and where the Flower Power Bulb is strongest at 280-30nm. They make bulbs they use to age wood, tan show pigs, and all kinds of stuff. 100w UVA bulbs.
This is a complete power kit including a SunHorse 120V @2.4amp ballast, 8 premium Leviton lamp holders (two per lamp), mounting screws and 4 of our best selling FR71T12 SG-1 UVA/B lamps.
Applications:
This versatile kit is mainly designed for curing, and is very popular for surf-board makers, luthiers of fine instruments and high production assembly line work. It has also been tested for cannabis production and wood aging. It is a solid, all around UVA / UVB lamp with extremely high output in the 365nm, plus output in the 315nm-320nmnm range and in the 280-288nm range to suppress bubbles and surface flaws. Proven for curing applications that need a 365nm center frequency.

Phillips UVB
Action spectrum studies in psoriasis have established that UV light with wavelengths between 310 and 315 nm can completely clear skin lesions at sub-erythemogenic doses. In contrast, wavelengths from 290 to 300 nm produce a sunburn reaction without any therapeutic benefit (1, 2). These findings led to the development and use of narrowband UVB (NB-UVB) light sources for dermatological therapy. Since its introduction in 1988, the Philips TL01 fluorescent tube has been used successfully and safely in phototherapy for many skin diseases (3-6). A major advantage was that burning of patients could be effectively controlled compared to existing photochemo-therapy modalities and broad- and small-spectrum UVB treatments.This led to 311 nm irradiation becoming the treatment of choice for conditions such as vitiligo (7,
and Psoriasis (13, 14) In recent years lamps using an alternative ‘311 nm’ light source have become available, offered as a cost-effective replacements for the Philips TL01. However there are some worrying differences between the two.Another thing to consider. The main purpose of the 280nm is to activate the Protien UVR8 to change the chemical profile, not to simply increase trichome count. That still wont change the cannabinoid profile. 280nm makes the plant protect itself.

| Ultraviolet C | UVC | 100–280 | 4.43–12.4, 0.710–1.987 | Short-wave, germicidal, completely absorbed by the ozone layer and atmosphere: hard UV. |
| Ultraviolet B | UVB | 280–315 | 3.94–4.43, 0.631–0.710 | Medium-wave, mostly absorbed by the ozone layer: intermediate UV; Dorno [de] radiation. |
| Ultraviolet A | UVA | 315–400 | 3.10–3.94, 0.497–0.631 | Long-wave, black light, not absorbed by the ozone layer: soft UV. |
| Hydrogen Lyman-alpha | H Lyman-α | 121–122 | 10.16–10.25, 1.628–1.642 | Spectral line at 121.6 nm, 10.20 eV. Ionizing radiation at shorter wavelengths. |
| Far ultraviolet | FUV | 122–200 | 6.20–10.16, 0.993–1.628 | |

| Near ultraviolet | NUV | 300–400 | 3.10–4.13, 0.497–0.662 | Visible to birds, insects and fish. |
| Extreme ultraviolet | EUV | 10–121 | 10.25–124, 1.642–19.867 | Entirely ionizing radiation by some definitions; completely absorbed by the atmosphere. |
| Vacuum ultraviolet | VUV | 10–200 | 6.20–124, 0.993–19.867 | Strongly absorbed by atmospheric oxygen, though 150–200 nm wavelengths can propagate through nitrogen. |

These are the par maps Shane got when testing with a Solarmeter uv-b tester? This meter measures 280-320nm. Looks pretty solid. Am I believing marketing bs? The spectrum charts are from the manufacturers, the par charts are what Shane got when he tested them.

. Argomax also does not go to 280nm. SC strongest range is 280nm-300nm.
Phillips broad band also only goes to 290nm
PAR Rating is useless and is not an accurate way of determining UVA/B. In reality, the less PAR of the Solacure is better. SC only goes to 380nm, is it a surprise it has no real PAR rating. It emits VERY LITTLE VISIBLE LIGHT. UVA/B is not visible. Visible light starts at 400nm.
Photosynthetically active radiation, often abbreviated PAR, designates the spectral range (wave band) of solar radiation from 400 to 700 nanometers that photosynthetic organisms are able to use in the process of photosynthesis
400nm-700nm IS VISIBALE LIGHT
Light from 400–700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it. Light outside of this range may be visible to other organisms but cannot be perceived by the human eye.
Makes me wonder why the person that tested puts so much emphasis on PAR when UVA/B has none????
Also the SC can run up to 80w.

Confusion is so great. It drives so much cannabis related business. If you don't know about something then you must be missing out so the only way to catch up is to keep buying until eventually somebody tells us We are good....until something potentially better may or may not be available so either buy it or wait for what's next or better yet, buy it AND buy what's next so you don't take a chance on being behind the curve.

All Im trying to do is replicate the sun. Nothing more.
All I know is the sun produces both UVA/B, and thats all I care about. All the other stuff is just going off on a tangent.
My only question with using these lights is?
Does the sun produce 280nm of light??
Answer is YES. So if a light doesnt produce 280nm efficiently, its not reproducing the rays of the sun accurately. Its really that simple. It either does, or it doesnt.

I vegged this plant under a 400w solis tek 10k metal halide last year and I cant help but think that the amount of UV the bulb produced was damaging my plants somehow
and honestly If I can avoid using UVC i will! My next grow i will be using the agromax pure uv t5 ho bulb and run it 12 hours a day! I will report back my findings.I grow using hydroton pebbles and rockwool grow cubes.
