I have a older Surefire M511A weapon light. Is it possible to upgrade this to LED?
Any chance I could upgrade the head to the newer vampire units?

Thanks,

Are these guys still in business?

They are.  Just give Kevin a call.

Sorry for missing your post...

Yes, you can upgrade it with a drop-in LED module (Lumens Factory SF-M3-LED lamp = $52.00) but that will limit you to white light only as it will not work with an IR filter.

The M3/M96x/M500/M900 series do not have a Vampire conv. module.

How many lumens does the led produce?  Runtime. I'm interested in this too

Malkoff Devices has upgrade bezels that work with M500 series Surefire weaponlights.  You can then use his M61 or M91 drop-in lamps.

The L.F. lamp is rated 800 lumens but it's not truly that strong... I'd have to estimate it at around 550 lumens and these drop-ins offer more of a flood pattern than long throw.

Yes, there is the Malkoff conversion but they are more expensive and do drastically change the look of the light setup.  For the M951/M952/618FA/618FGA we modify the Malkoff M61's to drop right in ($43.50 delivered on an M61 or M61L) so no conversion bezel is needed.  In the case of the Millennium 9v & 12v lights I'm not sure the MDM4 conversions that use the M61 or M91 lamps will satisfy all users but the M91T variant certainly provides a worthy price-to-performance ratio.

IF, you want to keep it all Surefire then there is always the KX9 Turbohead LED conversion but it will be over $200.
