One another design note..

Anyone thats used these cobs probably knows the beam is really strong in the middle at a somewhat narrow angle. Will be giving these angelina lens inserts a try. The thinking is it will even out the beam intensity before leaving the reflector.

They were available at mouser so I just ordered a few to test with this light

This is what the ends will look like for now. The hangers are ugly but functional. 4" L brackets screwed right into the t- slot, didn't even need to drill a hole. Screened the ends to keep fingers out and to hold the ac inlet

What did you use to cut the aluminum grill to fit?

Way to go, the fixture is one of a kind! :clap:

Looks great. Those lens inserts seem to have a difuser finish. What is the model number.
I have only used regular noctua fans.How are the noctua industrial fans.

Hey Pos!

Nice build, nice material/bauhaus design! I like the metal finish. Could be a part of a Mad Max movie, Lol!

This diffuser lenses looks really interesting and could be really increase efficiency in terms of light utilization / distribution. Would look good on my Vero's, do you have a link?

Just caught up with the action, looking nice! I am excited to see this lamp up and finished, very clean looking.

Got everything thing I need to finish this. 2 meanwell LDD 1000h to work with the far red and uvb. If all goes well should be running soon.

image.jpg

Didn't realize they are so tiny, perfect. Input voltage of 9-56vdc and output of 2-52vdc. Nice specs to work with, it will be able to run just 2 leds each, far red and uvb.
Not sure i've got this figured right, will find out I guess.

@salmonetin any use for the relay on typhon? How to use it? 2 temp positions also...code is written in for temp readings...solder mini usb to board and npt thermocouple?

Won't be using them now, just curious..

This LDD's works really great! I have 2 LDD350lw, but remember to keep the input voltage always 2-3V over the output voltage to ensure the best efficiency. You can of course more, but the bigger the difference the worse he is working in terms of efficiency.(higher Tc.) Which uvb is it? And about the lenses, can you provide a link or at least a part number?

I have a couple of them LDD at 700ma that i'd planned to swap in to use for my FR. I was a bit confused about how they function and whether it's possible to use them for fan power?. I was thinking they'd (@.7) be ok with a string of fans but big trouble if any fans blew (I tend to still resort to worrying & procrastination to make up for gaps in knowledge :-P)

...dear bro Pos....first at all... im inexpert on arduinos... i dont have arduinos or typhoons... im not a programmer...

...second... now i remember your typhoon...

...good news and bad news..

ok you buy on stevesled but the model seems to much an pre version of saltydog acuarium typhoon

...inside of Typhoon v2.1 zip... are the typhoon v3 pdf... good news check and see or read...

...but not an pde or ino code... i only see an hex file... maybe something can tell us if an hex file can translate on pde or ino file...

https://github.com/SaltyDog-Aquariums/Typhon-v2.1

...inside of v1 zip you have an pde file... good news ...we can look inside the code...

...but not a manual on pdf... bad news

https://github.com/SaltyDog-Aquariums/Typhon-v1.0

...i suspect if you solder the mini usbs at typhoon you can use it

but i dont know if code version v1 can handle with all...

...they said on typoon v3 pdf...

...It also offers 2 inputs via USB-mini for (2) DS18B20 Temperature sensors, an output for a 4-channel relay unit and Bluetooth lighting control via a Bluetooth Module (Purchased Seperately) with our Android App (Purchased Seperately)...

..if they use ds18b20 termp sensor i think you can use an thermocuple too both using one wire library on arduinos...

if typhoon v2 hex file can be translated to an pde or ino file we can see if the code can go with the extra conections...

...,maybe ive re read the info about typhoon controller on steveleds site but i think the last version published
for typhoon are the R20... showed comparaded with previous version R15...

...and all of these i know without buy nothing.... ..and without help...

...just by my curiosity...

...thats my grain of salt...

...ups.... for coneccting ldd drivers.. seems to me in coralux are examples
but first we need check pines to compare the storm pins with typhoon pins..
fot better undestand the physical conexion and the pins on the code...

saludos

Ledengin 5w 365nm...think they discontinued this particular one though.

Lens.....http://www.mouser.com/Search/ProductDetail.aspx?qs=7jhocJ3ivuTugbsxm5WASg==

@salmonetin...thank you...that info does help a bit. When i scroll through menu a temp readout comes up so I think I just need the usb and one wire setup...will look through your information..

Edit....my bad, 365nm is UVA. Don't have any UVB leds..yet. Forgot the UV range..:eyesmoke:

...then your typhoon came with code pregrabed....

...for better comprension watch tutorials about DB18B20... and tutorials about thermocouples...

https://www.sparkfun.com/products/245

http://bildr.org/2011/07/ds18b20-arduino/

https://learn.adafruit.com/thermocouple?view=all

or through amplifiers... 31850 or an old max6675...

...note curious... the reflow oven controller shield uses the max 31850 and a k type thermocouple...;)

https://learn.adafruit.com/adafruit-1-wire-thermocouple-amplifier-max31850k?view=all

..i hope you help the info...

....read when you can or like...

Hey Tazbud!
hmm! fans needs constant voltage. you need a step down module for that. Look on ebay, they costs only a few bucks! And over a build-in poti it's possible to adjust the fan speed.

Thanks bro, I just had these on hand (mines LDD700-HW In 9-56v out 2-52v..) The voltage would be self regulating? but 'constant' (+ over powered)? I'll probably just buy another 12v source but these bucks would limit the needed wiring (for my setup).. for fans as well as extra small diodes.

Thanks Pos!
Colour mixing seems to be interesting. Have you more infos on how they works?
I thought at first it was diffuser lense!
A Arduino controller is a fine thing, unfortunately I have no idea of the codes and how to program them...,Lol!
Some new stuff to be learned and again a few more sleepless nights, ufff!
But has to wait ..
Later:sleep:
