They said that their COB is encapsulated with Bridgelux led chips .Of course , you cann't see from the pic . http://www.ecosunlite.com/html_news/Real--Cree-LED-Chip-for-GROW-LED-10.htmlThey are lying to people. I haven't seen any Bridgelux cob that looks like that Chinese junk go ahead and buy it and you'll find out
grease is easy to use.Bonjour
Since i never use thermal grease (supraspl said grease is better) and saw what happened when you done it the wrong way, i decide to go with thermopads.I believe there is less chances to go wrong with pads.
If nobody can help me with this, i will buy the 30X30X1mm 6w/mk and cross fingers!!

Ground it if possible just to be safe.Hey guys,
Sorry if this is the wrong thread but I recently bought this jhx-10s5p driver to power my vero 29 3500k and was wondering if I needed to connect the ground wire or just bypass that and splice it with an ungrounded power cord.
HeyAre the galxyhydro LED's any good? I found a 600w for 249.99
lol it's not. 40x40cm is about 250 sq inch.Bonjour
16 sq/inch,it is 40X40cm...wow!!!with only 3.5gr...about 160 cob with it,am I right?
So for 1 it is ±0,022gr,much less,I guess,than what I saw on many bid...it is not a layer it is a mist of TIM,a shadow,a hint...now I better understand the tap tips (top!)
So now I know that if you are good with a butter knife,you would be with TIM...!?!
Have a good night©
Should/Can I Start My Own Thread?
What I was hoping to do:
For example, when I go to look at LED’s and filter the choices to Cree CXA3070 3000k’s on Mouser or DigiKey, there are still 135 different options to choose from. I would really like to know exactly (exactly) what I need.
- Build a nice hydroponic setup in this 2’x4’x7’ Mylar tent with COB LED’s.
- Be able to start learning by doing with the tent I have.
- After getting the hang of this, upgrading to a much larger setup and hopefully being to help the others out here who have medical needs for cannabis.
- Being able to use less COB’s that are more powerful would be nice for my initial grow space. I would like to use what I learn to make more of the same lights when expanding the room I have to grow.
- Get the exact mode/part numbers of what I would need, so that there was no way I could accidentally get the wrong part (things like 2-step/4-step, wattage/voltage, etc).
- I would like to grow from start to finish with the same lights, but then be able to add some on later to fine tune everything.
- Have someone (or a few people, or everyone) help me get this going from start to finish. Then hopefully creating a really great and updated tutorial for a project like this.
PS: I just got back from the parts store and had no luck getting what I needed... I need help...
caretak3ron a personal note, it's encouraging to hear the love for your friend come out in your words. I understand what it is to have someone that you want to help desperately, but, for which there is little you can do.
I'm not a cob expert, but I've made a few lights. There are a few choices you need to make. First off, are you wanting to drive the COBs soft for higher electrical efficiency and lower heat? That comes at additional cost, but it helps to choose between COB manufacturers. The VERO v2 COBs would be a good choice if you are going to choose to drive less quantity of COBS at higher current. If you want higher efficiency (resulting in more COBs driven at lower current), you should choose cree CXBs (generally you want CXB over CXA). Make that choice, and we can direct you to threads for which you can model your light. I'm sure @SupraSPL would be happy to chime in and help as well.
I am not much help but you will most likely find that it will take some trial by error to get every thing dialed in. Like humidity and temps might be the biggest challenge. I just "do it by ear" when unsure. good luck on all your projects CT. I use a milk house heater in my shop/grow room in the winter and it woks good all by itself although it's not as cold here in Washington where I live.caretak3r
Thanks for taking the time to respond and give me a heads up. I am not sure what it was I was expecting. I have never just signed-up for a forum and had my first post be a huge question. I figured I broke a rule already or said something I shouldn't have. Thanks for being friendly.
One thing I should have mentioned was that temperature is a big factor. We have a fireplace here, and that is the only source of heat we have. Outside it gets around -10°F in the deep winter months. The climate is extremely dry year round (like nose bleed-dry). I know I would have to do something to keep the temperature in a specific range. During the summer, it stays pretty cool. It gets up into the low 100's, and is very (VERY) dry. Our adobe house keeps everything around room temperature though. Not sure if a source for cool air and/or climate control would be as important in the summers here (in comparison to the winter and the need for heat). If I have to get a full-fledged solution for climate control (heat and cool), then I will.
- I was wondering if your suggestions would change at all due to the fact that heat will be a necessity during the winter?
I am pretty sure I am incapable of creating a thread (because of new user limitations, etc). But I was wondering if you thought I should try and make a separate thread for this whole process, or if I should post this elsewhere on the forum?
- Does requiring climate and/or temperature control have any effect on your suggestions? Or change your thoughts towards different conclusions when choosing between Vero and Cree?
I am going to ride this through from the beginning to the end and I would like to share the full progress and results.
