I have a tasty that has meanwell driver 2100ma I have to leave it on half or I fry leaves and even at half I still get leaf destruction. Tasty stopped using the 2100ma and has went to a 700ma would it be a good idea maybe to swap my driver out for one that runs around 1050ma or 700 ma to get more out of my light.
that makes loads of sense, depending on your height I would go with 1400 / 1050ma (I've not driven @700ma, sounds perfect for veg). My findings so far with my 2 lights are that I can get my 1050ma light to 10" to 6" from the canopy and the 1400ma 18" to 10" from the canopy. I've founds no difference in the 2 drive current bar the 1400ma gets that extra penetration and the plants can get closer to the 1050ma also the 1400ma adds about 3 to 4c to my tent over the 1050ma... if I could do co2 I would be driving 1400ma all the way.
