Who's been using HQI DE Bulbs here long term - results?

[wayner]

Has anyone been using HQI - DE Bulbs here for awhile, would like to know what kinda of results your getting with your sps as far as color.

Could you please advise ballast (e-ballast, ice cap, geisseman, AB, etc),
Pendant (pfo, Sunlight Supply, etc.) and bulb ab, ushio, apparently, there's a new de bulb on the market by geisseman 13K which according to some users is very nice.

Thanks
