The best 600w digital light bulbs

dont buy that HTG garbage..Sun pulse makes bulbd especially desiogned for the digital ballasts which are good...To clarify muself the enhnaced spectrum bulbs come in all wattages the Hortilux Eye Dual arc super Blue comes in 1000 watt only with the 600 watt bulb being released by years end hopefully.

I will be switching my hortilux for the dual hortilux.
After reading this thread. Thanks for all the info.

A 600 watt dual arc will be nice. I'll try it as soon as it comes out. Until then I use conversion bulbs for veg, and I'm thinking of trying
a Phillips CMH for veg, although I think those only go to 400w.

FF, what do you know about the 940w Hortilux conversion bulb for M56 ballasts? I think it's called the Ultra Ace. It's pricey, but wondering if being a primary MH first with added reds is better or worse than the opposite.

Dont know much about it. i never used conversion bulbs as they cost so much and now adays not needed as digital ballast run both direct so no need for conversion bulbs and lossing all the outc put a conversion looses.. On the 600 watt bulbs I found a place online that sells the hortilux eye enhanced spectrum 600 watt bulb for $74.99 each free shipping then take that and shop it at places who claim lowest prices guaranteed and they have to beat it lol

They don't have to.. They'll use the shipping time argument against you.. You'd need to make it obvious you're willing to be a loud squeeky wheel, and in this hobby that wouldn't be wise.. Worth trying though..

Not all digi ballasts are convertible. I have a Lumatek 600 and it is HPS only, would need a conversion bulb for MH.
The reason for my question is I have an opportunity to get a 1000w ballast and reflector for a good deal and I have read a lot of people like the flowering they get from MH, and others combine MH with HPS for best of both so-to-speak.

I thought wouldn't it be great if the opposite of the EYE hortilux existed with predominately MH spectrum with a second HPS filiment and that's where found the link to that lamp. But you are right, they are expensive but I did find one for only about $30 more than the 1000w EYE and I think I might try it out. I might run a standard MH one harvest and compare to the new bulb on the next while trying to keep everything else equal.

I have mainly used GE and Growlush bulbs and they have worked great. The bulbs on my last grow had seen 3 grows before that one and the bulbs still worked very well.
