Heat stresses plants not light.

Creepy Steve nailed it.

The only stress would be that there wouldn't be enough light... listen to Creepy_Steve... he's spot on....

stress? it *might be able to cover 1sq ft of decent growth. This assumes it's a high efficacy light around 2.6-2.9 umol/J. might cove 1.33sq ft if top end parts and running at spec sheet for best efficacy and heat dissipation etc etc... but shouldn't assume such things without looking into it of course. not familiar with teh spectrum lingo.. in general a warmer white with more red in it is better for bud development. if using seed to harvest, that's teh way you want to err in that respect. if you have 2 lights, a cooler ("blue") light will help axillary growth some minimal amount... i wouldn't spend extra for this sophistication, imho... small potatoes. but, a separate smaller vege light can be very useful and save watts.. tho prolly not getting smaller than 36w. i'd put one of those 36w led every 6-8" ... 8" if higher efficacy. then, keep plants directly under that frame of lights with no more then 3-6" portruding on either side (6" on axis that is perpendicular to what i assume are narrow strips).
