I have a surefire 660 classic series weapon light. How can i make it a 9 volt?

It should use the P60 (60 lumen) and P61(120 lumen) bulbs.

So basically yes.

Just know it wont add much throw. It makes the hotspot larger, not brighter. Not worth the penalty of 1/3 the run time IMO. Also the P61 at 120 lumens is NOWHERE near the MN10 125 lumen 9V lamp performance as far as throw. Dont think you can use the 6V HOLA to get 9V LOLA performance at the cost of run time.

Agreed, as the 9v MN10/11 bulbs use a built in reflector where the P6x and P9x use the smaller reflector built onto the bulb. Bigger reflectors get more throw.

For a weapon mounted light though, the P61 seems to be a tougher more robust lamp than the P60's. It also has a nice very round big hotspot. With only 20 minutes of runtime though.

You could also ad an A19 or A12(?) cell extender to the 660 and have 9v system that uses P90 and P91 bulbs, which still don't have the same throw as the MN10/MN11 bulbs (reflector again).

what would that run? Obviously trying to not spend as much as a new light!

I don't know about the other parts but a P61 lamp goes for around $20
I would contact Calvin from Brightflashlights, he has parts for surefires that isn't even in is forum plus he would know the best way to go about it.

Adding the A19 (20?) or A12 (25?) plus a 9v lamp (18-25?) plus the extra batteries is all it takes. You are still using a classic weapon light parts versus the millennium system. It adds an inch to the total length and adds another electrical junction (little more resistance means yellower beam).

You could replace your L60 Lamp Module with the LM90 Lamp Module (it uses the MN10/MN11 lamp assemblies in the "M3" bezel.
