What's really interesting to me is the comparison of the 4100K bulb with the Philips MasterLine EnergyAdvantage, the supposed efficiency champ for MR16s. I have the 24 degree, 35W version of this bulb, which is rated for 4400 CP -- in other words, with a much brighter AND wider beam, this 800 lumen monster should blow the SoLux away.
I picked up a couple more sets of optronics on ebay to house my stable of test bulbs. I currently have the Phillips Masterline 35w 17 degree and the Solux 3500K 35w 10 degree mounted. They're running at 13.2v with a lightbrain controller. A 18.5v Li-ion 6150mah battery pack powers them. I usually have the Solux running at 100% and sometimes add the Phillips at 66%. The trouble is I'm running out of dark time to test them out. Even getting up at 5:30am puts me outside at 6:05am and it's bright out. I do get 5-10 minutes of twilight at 6:30pm. This will change Apr 3rd after daylight savings time. I have noticed that cars will wait 5 or more seconds at intersections for me to passs.
