krunch,
did you email them showing this? I would like to hear what they say.
bought several a while ago, liked the different spectrum's.....
could NEVER get a good yield out of them, no matter what i did, but the plants looked good!
today i decided to replace them with new hortilux's and discovered this!
SHIT!!! i have one of those as well! it runs sooooooo hot! all the plants that were under it are yellow....
just moved that digilux to another room , over perfectly healthy green plants to see if it will yellow up as well.....
what ballast are you running? was it only the one bulb?
maybe keep an eye on that ballast this run.
^^ there must be a reason why my favorite online hydro store only offers the 600 watt 6.4k sun pulse bulb and none of the other ones. I was thinking about using this for veg.
When you guys say Ushio's, do you mean the Ushio Hilux? I was thinking about using these with some new quantum ballast. Not sure if they work with magnetic ballast.
