http://www.lumileds.com/uploads/600/DS162-pdf Hello. What do you think about these COBs? Efficiency seems good and they cost 1/3 of vero29 and less than 1/4 of cxb3590. I don't know the spectral data of the light and do not know how they work in grow practice, They are produced by Philips ...

So I bought some equipment off Craigslist and it came with a half burn out lighthouse blackstar https://www.amazon.com/Lighthouse-Hydro-BlackStar-Flowering-240-watt/dp/B004E662SA I'm trying to figure out what their drivers are rated for. It doesn't seem to say. I would like to refit them with...

Hello RIU, first time poster and I've been reading around alot. I keep coming across different opinions and such on good brands of lights and so forth. Question is what would be a good LED light for a 3x3 tent. I want the best I can get without paying 1000 dollars right now. I've been looking...

This is what Cree recommends in order to replace a 1000w HPS and I will be building this over the winter and documenting it here. Cree SMD Xlamp LED build that equals a Gavita Pro 1000w HPS...

Hi, sorry for a dumb question but I have read so much and only get more and more cunfused so again I am sorry about it must have to ask myself for direct answer to my question. Found Kingbrite on Alibaba that so many talked about and got these bins for the CXB3070 that I entend to combine with...

Shortly gowing to be running 4 Cree cobs fitted with angelina reflectors. Would it make sense to wrap the outside of the reflectors with aluminium tape so all the light is reflected out and down rather than leaking out the sides?

I'm just about to wire up four Cree CXB3590-0000-000N0HCD35G to a Meanwell HLG-185H-C1400B 200.2W 1400mA71-143V. Will this run the COB undimmed at 100%? I will be including a 100k Ohm Potentiometer across the dimming wires, with a fixed short resistor at 10k Ohms. How should I set the dim to...

Hey guys before I do my first diy Cob setup I have a question. What's the most important specs to look for when buying cob leds and drivers? Wattage + 3500k, warm white on the led and wattage on the driver? Here is the specs of the combo they are selling in a city near me. Cree brand...

These seedlings are both about 6 days old, and the Ghost Train Haze #1 is the big one that has been vegging for about 1 month. I'm planning to top the seedlings at the node(forgot which Node this is) to create 4 tops and then flower them. I think the ghost train haze will be flipped to...

Legal medicinal grow, basement. Will probably try to convince roomies to allow a 4x4 tent, but may go 3x4. DWC hydro in 17gal containers. So far 7 normal seeds popped and unsure of sex (~3 weeks weak fluoro) Will be buying light(s) very soon. Had previous positive experiences with weaker...

I have two 36" heatsinks and 4 Cree cxb3590 for each. I tried hooking my light up with my B version meanwell 185w, and thought it should all be connected right, well i never could get it to work so some wiring must be wrong. I'm asking for some help on wiring since I apparently forgot some...

Trying to find some info on this but havent succeeded thus far - is it a problem if moisture gets onto the surface of active COBs, like from a humidifier? I can see documentation from Cree saying that COBs were tested at 85% humidity, so i dont know - i have emailed Cree and am waiting on a...

Hello rollitup growing community, I have just finished my first set of DIY grow lights. Its a simple setup for a 2x3 or 2x2 grow box. I am using an HLG-185H-C1400B driver, currently 2 Cree CXB3950's and some cheap but silent Alpine fans on two separate heat sinks. My driver runs at an operation...

Hey There! I have a light I built and I am just starting with COB lights and am trying to get a ballpark distance for fresh seedlings. I have the light placed about 30 inches above atm and have searched and read a whole bunch of threads from all over the web and the...

http://www.bcblondes.com/category-s/100.htm You guys seen these? Anyone using them? CXB3590s (or CXB3070s) and Mean Well drivers in these familiar old cases... What do you guys think? The prices seem really good for the number of COBs, wattages, drivers, all the specs... I guess the only...

This current grow is both the first grow with my very own DIY COB LED grow light, which is tits, by the way, and also my first time growing Pineapple Skunk by Humboldt Seed Organization (HSO). This will also be my first attempt at trying out a proper SCROG. I have utilized pinching, pruning...
