@homie123, as with any light, it's always best to measure things - measure the temp or just place your hand on the canopy level - if it heats up, it's too close. I'd say that around 40-50cm you should be ok, but like I say - measure it and know for sure. If you can, get a PAR meter you can measure the exact place for your light that's giving you the best output for the plants
