Breathing new life into the surefire L7


Oct 5, 2006
Greetings fellow CPF members,
I have a question for those who do modifications: has any one done a mod on a Surefire L7 to run on a lithium ion battery pack with a more efficient LED/driver combo then what is stock? My L7 has sat on the shelf unused for the last 3 or 4 years because the B90 sticks no longer work and I don't think it is a sound investment to buy any more B90 NiCd batteries as they seem to develope memory problems fairly quickly. In addition I have been hunting around for a good after market NiMh B90 and have not been able to find one. Any input on this would be great and I am also willing to send this L7 off to be modified if necessary.
