What are some options for LED heads for these or just replacement bulbs?

The gun will fire so I don't need a light bright enough to burn through someone.

Does not need to be that much brighter, a little would be nice, but mainly after a little extended battery life.

Also a huge plus would be if it is the same size as the Surefire head so I could still use my Surefire flip up cover or just an internal upgrade.




Thank you for any suggestions.

Somebody enlighten me on the TX-4 LED conversion I am reading about.

Likes, dislikes, is the head diameter the same as the original Surefire M500. I have a Surefire flip up cover on my M500 and would really like to still be able to use it.




Still up for other suggestions though.

just got an M500 so I am also interested!

Have messages to TNVC and others asking about the LED units. Hopefully users will comment. But whatever I find out I will post here.

Thank you for the quick reply. Guess you can ignore the same question I asked on your Industy Forum. Have not read one negative comment on it. My biggest concern was the head diameter and being able to use my Surefire cover that I really like.

Will contact you Monday with my order. Going to see if a few other people want in on the order before I place it.

Over the past several months I have become something of an evangelist for the TX-4 conversion on the M500 The previous lack of a viable M500 LED alternative is something that I had been bitching about for well over a decade. My first TX-4 changed all that.

For me, the ergonomics and switching options of the M500 make it an ideal weaponlight for the type of shooting and training I do. The TX-4 corrects the only gripe I have with the system. You will be extremely happy with yours.

To give you a visual unit comparison, the top carbine in the pic has a TX-4 head installed, and the bottom one has a standard Surefire OEM crenellated bezel:



Good luck TWPayne

Hey CJan, would you be able to measure the head on the TX-4 and your Surefire head and tell me the difference. Above TNVC said they were the same. I read somewhere that the TX-4 was smaller than the Surefire.

This is partly your fault you know. It's also your fault that I am Acog shopping right now.

Thank you, (i think, lol)

Hey Terry, I'll take exact measurements and report back as soon as I get home tonight

Off the cuff, the TNVC bezel is a bit shorter than the Surefire bezel-but the diameter between the two is very similar.

Sorry it took me a little longer than I had expected to respond-all hell has been breaking loose at the office this week

Anywho, the diameter across the bezel is nearly identical between the Surefire and TX-4 heads at 41.25(+/-)mm:


The TX-4 head is only a couple of hundredths smaller than the Surefire.

There is a difference in length between the two (the TX-4 is a bit shorter), but that hasn't mattered for any of the accessories I own.

Hope this helps

Exactly what I was looking for.Thank you so much. I will put an order in for one on Monday.
