Its really a better if you learn how to treat light and hanging height. How big are the plants under it and what light are they used to? Is there lenses on the light? Try to up intensity little by little, look for signs of too much light: new growth is pale green and the plant has a poor saggy stance. Keep temps up over 80F atleast. Once your at 100% with happy plant stsrt bring the light closer slowly, looking for same signs. There isnt any right hanging height for any light, only the plant can really tell you that. All thhough i agree that there are wrong hanging heights.
If you can just keep buying Cree inc. stuff. SOB is over 70 bucks now and may never go below that. Thanks.
Yeah I’ve had this light since 2012, but I forget how to hang it every time I pull it out. It has narrow secondary optics and the 5w chips require it be hung no more then 22in, but with seedlings it’s 30in and dimmers on low. The seedlings are two inches tall and about 8-9 days old. they were growing awesome, then I lowered the light and they basically stopped growing, that and my temps were a bit low. I raised the light and the temps and overnight the third set of leaves started coming in. I think I’m golden, thanks to everyone for the replies
I’ve had it for ages and shouldn’t have issues, but I seem to always forget how to hang it because it’s a oddball light with really bright chips and awesome secondary optics that needs to be hung higher with dimmers on low, unlike a lot of the other lights I’ve used. Got it figured out tho thanks for the reply
