I had the opportunity to give the Lumens Factory EO-13 (13V 700 lumen) lamp a good workout tonight. It is in a Wolf Eyes M90 with extension tube powered by three Wolf Eyes 168A (2200mAH) cells. This was an informal test using another Wolf Eyes with a 250 lumen lamp on fresh batteries as a comparison at different times during the test.

The throw and total output of this lamp is amazing!
For the first 35 minutes of continuous operation I could not discern any reduction in output. From 35 minutes to 45 minutes there was probably some reduction in output but the EO-13 still walked all over the fresh 250 lumen lamp. By 50 minutes the EO-13 was still marginally brighter but the beam color had a tint of yellow when compared to the Alpha-Nine on fresh batteries. By 55 minutes the output of the EO-13 was about on par with the 250 lumen lamp on fresh batteries. By 58 minutes I could tell the output was fading fast and the protected cells kicked off at 59 minutes and 15 seconds of continuous run time. This was much longer than expected as I believe the EO-13 is rated at 40 minutes.

Warning - I did not heed the heat warning of 5 minutes continous use. However, even though twenty degrees warmer than last night, it is still pretty chilly in Iowa right now at a little below zero Fahrenheit. During the near hour of continuous use the body temperature of the flashlight never exceeded "uncomfortably frigid". The front third of the bezel was somewhat warm but not enough to keep my fingers warm - I am guessing no part of the exterior ever approached body temperature. Immediately after shutting down we felt the batteries and the back two were very cold while the one nearest the lamp was maybe at room temperature.

I hope these ramblings are of value to someone. Not very scientific but a gauge of performance during real use. I find this to be a very useful lamp and am pleased that the runtime is longer than I expected.

Thanks Lloyd, love the description 'the body temperature of the flashlight never exceeded "uncomfortably frigid".'

Sounds good; it was expected that the EO-13 would run higher than the 250 lumen rated assembly. Nice to know that it keeps on truckin' even until the end at almost an hour. I live in southern California though, so freezing cold is nowhere to be found and my M90 with similar setup will not last past the 5 minute warning.

Just curious, what is the Alpha-Nine? Is that the other Wolf-Eyes you tested against? I haven't heard of it until this post.

Sorry, I should have said RICO Alpha 9. My brain hadn't thawed out yet when I submitted this post. It's a nice white floody lamp that works well on two 18650s in the M90. Paul in Maryland has some good input on these.

Effulgence,

The Rico Alpha-9 is a lamp assembly we made for Rico-tactics. The specification of the 250 Lumens is actually a HO-9 (320 Lumens) lamp in a D34 reflector with heavy orange peel. As the coating is different from the D36, so it gives a more floody beam. There should be two versions of RICO Alpha-9, one is the first version which draws about 1.3A (250 Lumens), the later version (improved version) is a HO-9 (320 Lumens) which draws about 1.5A.

Thanks for the information Mark - I didn't know it was one of yours. Is there any way to tell which version of the Alpha-9 I have by looking at either the lamp or the packaging?
Thanks,
Lloyd

Hi Lloyd,

Many of the lamps you guys tested against the LF line are made by us actually, LOL. :D
But we can tell people that the RICO is made by us because we have agreed on letting the public know when asked.

It is hard to tell because I understand that RICO sold the 2 versions with the same packaging and the LA they requested looks the same. The only difference is the filament design.

They did not sell the 1.5A improved version until resently, so I would think that the lamps that comes with the torches are the 1.3A versions. If you brought a replacement LA from them resently then it should be the 1.5A version.

They are coming up with a new and improved Alpha 9, called the Beta 9. I can't expose too much info, but trust me that torch is GOOD. :)

Go check them out on their new website and you could see the torch in action mounted on an AK-47 and a FAL. The torch (with our lamps) can take the punishment of these 7.62mm Rifles on FULL AUTO!! :D

Interesting. The quality of construction of the lamps looked similar, now I know why. I probably have the first RICO version as I bought a bunch of these lamps on a closeout sale. Great floody white beam though for when I don't need the awesome reach of the EO-13.

Ah, so the rumored "improved" Alpha 9 was true. Nowhere could I find mention of it after one CPFer hinted that he would be testing it. And a Beta is coming?

Much as I admire the LF-branded lineup, I prefer floods; I've just bought a Surefire P91 from another CPFer, to use with my 2x168A D26 setup. I've chosen the Wolf Eyes 13V for my 3x150A setup. But the 13V may be dethroned by the 1.5A Alpha 9 or the Beta.

For my 2x150A EDC (everyday carry) light, I do use an LF: the HO-9. But who knows? the Lumens Factory (RICO) Beta may earn a place in my pocket.
