Where to buy bi pin bulbs for Surefire M4?

[Fuchshp]

Good morning

Where can I find bi pin bulbs for a Surefire M4 on 2xLiIon? WA 01111 seems to be discontinued years ago. Are there other options?

Kind regards,
HP

Did you check Lumens Factory? I think they have some M gear.

Yes, they do. Cheaper would be bulbs without light assembly to put them in a tad customs bi pin adaptor. This bulb here seems to fit with 2x17670.

I never seen they sell bi-pin bulbs.
For less brightness and longer bulb life, WA1274 will work.

Fivemega, thank you.

Besides high output bulbs it would be nice to have bulbs with less brightness and longer runtime. I just asked James from Malaysia who sent me a PM yesterday to sell WA1111 if he has it too.

Is bi-pin the original lamp for the M4?

The original lamp is Surefire MN60 (lower output) and MN61 (higher output).

Bi pin bulbs need a socket.

That's what I thought. Lumens Factory has four incan lamp assemblies that should work in an M4. One is a direct replacement that will run on four CR123 or two Li-Ion. The other three are direct replacements for the M3 light, but should work with two Li-Ion cells.
