Question: work on 6z? current bulb assembly and coil on mine seem to be fused together
Document: The bulb was advertised as an american made Cree bulb however it is manufactured and shipped from china. It required a little tweeking of the spring to get it to work in my surefire light however it does work very well and is very bright. Considering the low price it is a good bulb and I would recommend it.
This replacement bulb assembly is an excellent upgrade or replacement for surefire flashlights. It was drastically brighter and the battery life increased as it is an LED and not incandescent. It also does not make the flashlight hot to the touch like the standard bulb which is very helpful when operating in already hot environments like the desert. This is an excellent product and I am going to purchase it again to upgrade my other surefire flashlight.
Fortunately, though, the lamp assembly does unscrew from the machined aluminum reflector that needs to be reduced, so there is no risk of damaging the lamp itself when performing the modification.
I put this in a Surefire 6P body, but didn't fit. Remove the large spring, and it fits fine.It will not work on the plastic Surefire G2 body at all, since it doesn't make the necessary electrical contact.The light is bright, but nowhere near 650 lumens.
Great bulb, very bright, all I had to do was install it, going to buy two more, well worth the money.
I used this bulb to replace a very old Surefire LED. With slight modifications to the outer spring, this bulb has performed flawlessly.
This bulb in not suitable used for P6 surefire flashlight it big diameter and can not be use be aware any body to buy this for p6 surefire model
The brightness of this led bulb is impressive, I just installed it on a Surefire P60L plastic  body, I had to remove the big spring it comes with and it went right in. I highly recommend this product
Great product. As others have posted, I had to remove the included spring as this has a longer reflector housing than the P60 OEM light bulb. But now my 6P is now back in service much brighter and without all the heat.
I have a very old P6 bought in the mid 90's. It served me well on duty. I decided to upgrade and bought this bulb. I had read other reviews as well as the sellers comments and removed the large spring. At that point it was a &#34;DROP IN&#34; replacement. It is very bright and I am very pleased.
