That setup would give you 25w per sq foot which is a reasonable amount of light, if you are planning on concentrating this in half the tent then have the mover oscillate to and fro to cover the full area, that would give you 50w/sq ft for half of the canopy, this might be excessive and bleach your tops. I'd say you are a bit short of the mark with total wattage and a little too high with localised wattage so the results could be perfect or cause problems, I for one am intrigued to hear how it works out.
The VERO29 can take that much power data sheet says this particular COB can take 169watts thats with different drive currents and voltages if you can keep them cool. Few months ago i got a pretty good deal on 12 cpu coolers for about $1.50 USD each so I will be using them says it can handle 95watts TDP. Im basing this build off Timber Grow Lights 400watt Vero29 kit but not willing to drop 5 bills on a light system I can build for half. I know I should use a PPFD meter to get the canopy dialed in to around 800 - 900+ umols in flower and mabe 600 - 700 in veg need to look more into it, That raises another question Do FLUX, PAR, PPFD meter's work with cobs... I heard somewhere they need to be calibrated for LED...just not sure if they give accurate readings out the box with COB's And still confused about how to properly measure the given amount of light these badboys put out, can i get away with a cheap $30 LUX meter or buy a really expensive meter to get good TRUE readings?
clu058s can 'take' 500W but people still run them at 50W
depends if you need 'true' readings
