Solarforce L2P Projects

Greetings,

In the fall of this year, I desired another Solarforce host and wanted a 3 mode drop in. At the time I was not aware of the Ultrafire XM-L T6 three mode but I am quite happy with a good XP-G R5. I ordered a Lumens Factory D26 XP-G R5 300 Lumen 3 mode memory module and made some observations.

  • The LF 3 mode is regulated to a maximum of 1000 mA for longevity, durability and reliability.
  • The LF 3 mode is 3.6 - 13 volt and allows CR123, 16340 and 18650 batteries.
  • The LF 3 mode has a warmer tint than most cooler XP-G R5’s
  • The LF 3 mode comes with a textured OP reflector and the texture is smoother and less orange peel than a Solarforce OP reflector. Beautiful beam pattern.
  • The 3 modes are in order of Low, Medium, High.
  • The 3 modes have a PERFECT light level spacing of 5% - 30% - 100%.
  • The LF 3 mode is a bit expensive at $ 27.00 USD but the construction and packaging is high quality as well as unique mode spacing….well worth it.

Overall I am very happy with the D26 module, but due to the 1 amp regulation and warmer tint it is less bright and appears more at 250 – 275 lumens than 300. I’m fine with that and find the well spaced Low and medium modes are very useful for closer in work as they are not too bright. I like the differences between the Lumens Factory warm tint 3 mode and the Solarforce very cool tint, very bright 5 mode modules.

The Black unit specs:
- Solarforce 2011 Black L2P Body host in HA level III.
- Lumens Factory Cree XP-G R5.
300 Lumen 3 mode Premium LED and OP reflector. (3.6 - 13 volt).
- Solarforce S11 Tailcap switch.
- Solarforce B5 Medium crenellated Bezel.
- 14mm Glow in the Dark switch Boot.
- Uses 2 x CR123 or 2 x 16340 or 1 x 18650.

The Natural unit specs:
- Solarforce 2010 L2P Body host in Natural finish in HA Level III.
- Solarforce Cree XP-G R5.
300 Lumen 5 mode LED and OP reflector. (4.2 - 8.4 volt).
- Solarforce B3 Low crenellated Bezel.
- Uses 2 x CR123 or 2 x 16340 or 1 x 18650.


It's under driven It should be 1.5Amps, 1Amps(or 0.45Amps) and .01Amps then it would be close to perfect.

It's expensive.

Hey there how2,

You are absolutely right, and if driven to 1.5 amps it would be perfect and would really put out an honest 300 Lumens. However the 1.0 amp is the Lumens Factory manufacturer spec and this got me curious so I did some current draw measurements and I can't get that out of it. I did buy it for the 3 modes, but Yes, I was expecting more. Much better current draw on the 18650 Battery. Just over 800 milliamps. Might have to change my satisfaction level from Very Happy to just Happy. I don't know where else to get an XP-G R5 3 mode that is Low, medium, high at 5%-30%-100%.

Soshine Batteries (RCR123) 2 x 16340 @ 4.05 volts each.

Low = .033 A, Medium = 0.147 A, High = .460 A

Soshine Protected Battery 18650 @ 4.05 volts.

Low = .049 A, Medium = 0.262 A, High = .834 A

Hi Photon, great pictures!

Great photos! I can tell you know what you are doing with a camera. If you find yourself with some time I would really appreciate some detail
Photos of the lumens factory dropin. Photos of the driver pill junction and the wire to star solder points under the isolator disk. I just want to see how these expensive dropins compare to Chinese ones and homemade ones.
