When you get a chance, I'd like to know what e-ballast you used for the Philips CDM-150W ceramic metal halide lamp. Have you noticed any
flickering of the lamp?
Also, for those eVo owners wanting to try a similar e-ballast/third-party lamp mod for the eVo, could you provide more detail on how you modded the eVo so your 150W lamp would fit?
The single ended 150w cdm bulbs fit in the single ended (1.1) holder without modification. I bought the CDM150-SA/T 942 (THE bulb to use according to research, has the color temp of the regular cdm-150 942 but has an even smaller arc) More info
here. The Eballast is specifically made for ceramics (says on label "for 150w ceramic metal halide bulb") so no flickering there. The brand on it is Advance, but i cant remember the model number.
Here is the ballast family info. I found it by searching ebay for "150w MH Ballast" or "150 MH Ballast". I got very lucky, as it only ran me $50.
Edit: Also about the ballast, i just followed the wiring diagram posted here for adding a coil and core ballast to find which leads i need, and the leads from the ballast were labeled. Electrically quite simple, all done with wire nuts, no problems so far, about 2.5 months. As far as making it fit... well... brute force was applied. Old ballast removed, some internal trimming, and major external drilling and cutting. I ditched the power receptical and just hardwired the power cord (thats where the ballast wanted to land). The only thing holding it in place is the snug fit from the two halves of the case and a hook fashioned from a paperclip to keep it from sliding out the rear.
