Light is not consistent - takes time to turn on - flickers - new battery - Crimson Trace Tactical Light for Rail-Equipped Long Guns, 900 Lumens

When I first received this light it was excellent. The light turned on immediately and was bright. I have had it for barely two months, and have turned it on maybe 10-20 times for short periods of time. Now the light does not turn on right away after pressing the button. It takes about 15 seconds for it to get bright, and now when it does get to full brightness it flickers. This is not something I can recommend to anyone. Crimson Trace is a great brand, and I feel bad writing this review, but this is unacceptable especially in certain situations.
