That's why we are all here. To trade ideas. Build. Test. See what works. Education. Open source. With the advancement of led technology and forums like this.A little self education will take you far. And I'm not stopping with this light build. I have a couple other build ideas in mind.

Passive. Not as much heat as you think. If you have any airflow in your grow area at all there is no issue. I can lay my hand on the heatsink and keep it there as long as I want. Even without air flow there would be no issue of overheating

Yes. 3 will always be drove at 2.1. Like right now. 3 are at .700ma 3 at 2.1. With another 2.1 amp driver. It would just be more flexible

That's my plan as well. Only my hlg 240 is dimmable. The smaller driver is not. It will be replaced to just do what you are wanting to do.I have..another hlg 240 c2100b on the way already

I had an extra driver and wanted to use it Plus I wanted to experiment a bit. Its why I went 3000k and 5000k with 2 drivers. I can flip the drivers to either string of cobs.run either softer or harder. It's testing and playing around. Growing should be fun and learning. One driver 700 millamp...

Yes work with vero 7. Just go look. All the info is there. And yes. Heatsink,cob. Pad. Is under $50 for a complete ready to mount setup

http://www.rapidled.com/pin/ Predrilled and tapped. Even get all the screws. And I used the thermal pads. .80cents each

Because I didn't want to. That is the beauty of diy. You can build like you want.Not like everyone else

Besides framework. About $325. I already had one driver @Enigma Everything came from rapid led And they are not a combo. Bought separate. Heat sinks where $19 each

I didn't buy a kit. I built the frame myself. Ordered everything individual

:)

Light is done. Turned out well. This site was a big help. Lots of info on this site . Thanks everyone pimped out with Mau5 slaps @Growmau5

I can't send you a dm on mobile

If there is no massive lead time. I'm in for 2 boards @VegasWinner

ok,, here is my thoughts on the light. 6-140mm pin heat sink 3-Bridgelux VERO29 3000K 80 CRI D 3-bridgelux VERO29SE 5000K 70CRI poke-in total cost $248.40 using 2 drivers. the one that i already have. the lpc-100-700 and a hlg-185-c1400b each driver will run 3 cobs,and depending on veg or...

3x3. Sorry I forgot to add that

More into the diy myself. I have did a couple 3 watt led builds. But would like to do cobs. I was thinking 4 Vero or Cree 3070's. I know I can do a Vero build for that. Not sure on the cree. And I want one spectrum for entire grow

jay40353New Member Ok brainiacs I have upgraded my grow area and I have got rid of all my hid lights. And will be going to cobs. All I have right now is one driver. Lpc-100-700. I will need more.and I know I will be cooling passive. Unless I can get a better build using cpu coolers. My question...
