Heatsink help for 6 vero 29 panel im building

Im putting together 4 pannels for a 7x7 room each pannel will have 6 veros on it im having trouble coming up a layout for the best posible spead pattern

You can use 4 inch chunks of the 4.6 inch serrated fin heat sink from heat sink USA with a 120mm fan on each one, make 6 foot bars, space the lights at about 1 foot, space 4 bars evenly, 1.5 foot apart or so in the tent.

I was wounding if it would still be good not run a 6 foot bar but maby a square pannel with 6 lights

You could build 4 square panels with 4 lights each, however, I think you would need really big squares to evenly spread out the light over the canopy. I was recently working on designing my next lights and I went through a bunch of different build concepts, in a large part because I was attempting to save a few bucks here and there, and ultimately, if I wanted to get the best light distribution I just had to bite the bullet and spend a little more.

Sounds like u no what ur talking about i have another queston about drivers i was going to use 4 hlg 185h c1400 but cant find any one who has them in stock what would be another drive that is simular to hlg and has a dimming option cause i only want to run the diodes at 50 %

4 lamps as shown would provide great coverage at 18-20" height. One cob per foot under the lamp and a blank in the center since it will be bright as shit there anyway. Other diagram shows per lamp layout with 2 heatsinks, LED and fan drivers, bolted together with aluminum angle and/or channel.

Also, if you're never going to crank them up, HLG-185h-c700 but honestly that's not a lot of light for a 7x7. I would suggest 2 HLG-120h-C1400s per lamp. If you really want high efficiency low current check out the CXB 3070 at 700ma, more light than the Veros at low currents... still not a lot of light for that space though.

Sweet i will look into it what would be a good amount of light and how do i figure the cost to run each pannel

If i did this right then it would be 1700 watts of led so it would be 36 cxb3070 12 mean well hcg-120h-c1400 and 6 3.5 ×6 heat sinks does that sound more like it and also how do i figure out how much 1700 watts is going to cost me ?

I run 9 in an area 40x46 inches. I can run each at approximately 100w. 600 does nicely.

I dont see the point in running them at 100w when everything u read says run them soft the more effient i swapping out my hps 1000 for leds to save money on electrical cost long run not spend the same amount as i would with hps

Tons of info on the site.

I think that's in a good wattage range for the effeciency. The majority of the cost is in emitters, drivers, heatsinks in that order, along with hardware, bolts, wire, terminals, fans, etc.

Should i grab another driver for the fans ?

And aslo is there a way to get a digital read out of the amps for the driver when its running so i no where im at as i turn it town or up ?

A multi-meter can give you the electrical readings. The fans generally driven at 5 or 12 volts so would need their own rectifier/power supply. I recently asked about fans.
