My :twocents:x3:

I have a Sunm4st3r Super MH Cool Deluxe 600w that suffered premature failure on my Lum4t3k 600w digital ballast (and was replaced by my fave d00ds @ Grown Hydro , love 'em!)... just wondering if it might have been due to the spike thingy that someone mentioned earlier, or if I just got a lemon bulb @first? I have heard that L. makes an adapter thingy that might help ameliorate this effect, but not heard much commentry.

This particular bulb/ballast combo is recommended by the distributor in my area, but they might not be aware of the problem. The bulb itself has a great spectrum, and was insanely good for veg (as well as tanning!). Am thinking of trying the bulbs that L-tek puts out next time I buy one, but the Life Light Tech bulb sounds kuul... can't seem to find the Lmtk ones in 600w :wtf:

The Uv-B thing, as well as the max exposure thing are great! This confirms something I've suspected for a bit, that the plant likes (and NEEDS!) a bit o' noonday sun, but doesn't wanna overdo it I'm just using killa fans rather than a cooltube @the mo, and the plants seem happier now that the bulb itself is an average 14" from 'em.

OMG, just noticed the time--have to go home and prep some water for the goils tonight!

Kudos to all wonderful informative posters here!
