Great upgrade for my old Surefire 6P. Easy install and much brighter than the old incandescent bulb. I don't know how durable it will be or how long the battery run time is.

I have two surefire lights that I'd not used in years really. These things were great back in the day (20+ years ago) but by today's standards, were quite lacking. I ran across this item and bought one to try in my mountable light. Needless to say I was highly impressed and purchased the 2nd one, which arrived today. 5 stars all day, but the support spring supplied with the new bezel (gold spring in photo) does not fit. The outside diameter is too large to seat inside the light assembly where it was designed to. It's mostly irrelevant with the led anyway, and so install without it does not affect function. I'll definitely pleased with the purchase, these lights might now almost be worth the price paid for them 2 decades ago.

I was teetering between three and four stars because this is not an exact replacement for the one that blew out. But it is so bright that I decided to keep it and deal with the slight fit issue, so four stars it is. The bottom portion is too thick; the original tapers to a smaller OD, fitting into the body of the flashlight deeper, so the bezel doesn't seat all the way and it leaves a gap. This may or may not affect the waterproofness of the flashlight, but this is my indoor light, so that isn't as important for this light.

Perfect fit (once I removed the large spring) in my G2 Nitrolon Surefire flashlight. The batteries I had were getting low and would barely light the factory incandescent bulb. Using the same batteries with this new LED bulb, the light output was very bright and strong. With new batteries, it was outstanding. Very happy with this purchase.
