I've just bought a DIGI-LUX 400W HPS, as its has the same spec as the Eye Hortilux Super HPS.. minus the extra 30W.. but is actually meant to work on a Digital Ballast, the digital ballasts, and Digi-lux bulbs run at a higher frequency than the Hortilux and old skool magnetic ballasts.. and because of this the Digi-Lux are alot brighter and give outstanding Lumen projection.
Also its a know fact that Hortilux bulbs need replacing alot because they are being run on Digital ballasts and the clash causes them to flicker ever so slightly.....and after a while this reduces Lumen output and eventually kills the bulb!
However Digi-Lux have worked past this and essentially has the power of the Hortilux but transmitted at a higher frequency, through the power of a digital ballast and out performing the Hortilux in the process..
The bulb plus postage came to a Staggering £91.99 ... but thats the cheapest I could find it
~ nevermind.. at least I have it now
!!!
I was previousley going to go with Hortilux, but after stumbling on this info, Digi-lux is now 'the New Hortilux' of the digital generation
