I do not write in much but read alot on this forum, just wanted to say Emissive Energy (Inova) is very good on service after the sale. After reading a few other posts on the fine service from Inova, I sent my T1 which had a poor beam quality (shadows and yellowish color) to Emissive Energy following Dorothy's step by step email. A week later received a new T1, excellent beam which is also much brighter, this T1 uses two cr123s. Thanks Inova from Bobby a satisfied customer.
