BESTSUN Ultra Bright Flashlights XM-L2 LED Bulb Single Mode 1200 Lumens Drop-in P60 Design Module Flashlight Replacement Bulb Repair Parts for Surefire C2 G2 Z2 6P 9P G3 S3 D2 Ultrafire 501B 502B

This thing is amazing! A bit brighter than the stock battery in my Ultrafire WF-502B, the solder job on the exposed circuitboard where the positive terminal is (the coil inside) is also a better job than the stock version, which is very lightly soldered, which also acts as the 'support' for the circuit board to stay in place. I drop this thing on concrete pretty regularly, I work in a warehouse and the company doesn't believe in paying for silly things, like replacement fluorescent bulbs for our overhead lighting so I can see what i'm doing... But this thing lights up a dark trailer like it's day time, and I can count my inventory in confidence, knowing I'm getting an accurate count. I will be buying a few more of these to keep as spares. Dont wonder if this is worth it, because it's better.

I dug up my old Surefire 9P that uses three CR123A batteries and had a P90 incandescent lamp with a 105 lumen output. It still works, but pales in comparison to modern LED flashlights. There are some high-end drop-in LED lamps available for the 9P, but they are very expensive and not worth it considering the low price of a high performance LED light. I figured it's not risky to try out this lamp for my 9P due to the price.It fits perfectly in the 9P after removing the large spring. The light is a nice cool white and not super blue like some cheap lights. I'd estimate it to be around 5000K. The original P90 lamp was probably more like 2000K. There is a good beam in the center with some spill (original lamp is just a beam). No idea what battery life or lamp life is, but for the price I am very satisfied to get more life out of my 9P.

wanted to update my Surefire P6 I've been using since the GWOT in 04 and this bulb upgrade was just what the doctor ordered.

!!ORIGINAL Surefire P60!!It fits, read instructions and REMOVE spring. Works better than my broken bulb.Does not fit with spring.

Had to replace the bulb after trying rechargeable batteries (blew the bulb). It's a good bit brighter than a normal bulb. Quite happy.

Absolutely not a direct fit for the p60. If I could have given it 0 stars I would have. Can't even put the top to the flashlight down far enough for it to on. Don't buy

I have been carrying my good old trusty flashlight for many years and finally gave in to the newer brighter ones ( mostly Chinese made) because of the brightness. My old eyes need more light. I bought this upgrade and now I’m back with my classic light again.

Works great. Be sure to remove the outer spring for Surefire lights
