Souyos Ultra Bright XM-L2 LED Bulb 2000 Lumen Drop-in P60 Design Module,Single Mode Flashlight Repair Replacement LED Bulb for Surefire Hugsby C2 G2 Z2 6P 9P G3 S3 D2

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.

Brighter than expected, well worth the money. Much brighter than a 1000 lm bulb. Not sure about the 2000 lm but bright.

Definitely brighter than original. Followed instructions and works well. We'll see how long it lasts compared to original.

Got one to upgrade my Surefire 6P LED. Works good. Fits perfectly. It puts out a solid white beam and is fairly bright but is definitely NOT 2000 lumen that's advertised. Still it is definitely worth buying. Gave my old light a nice upgrade.

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.
