Streamlight Instructions say ALKALINE ONLY

Who was it, Brightnorm??, who toasted a Streamlight 4AA ProPolymer LED on Lithiums? I got a shipment of 5 Streamlight 3C LED lights in and they had a generic series brochure for incandescent and LED that says "ALKALINE ONLY" I don't recall the brochure with the 4AA...but it came with the 3C and it was generic for the group. This even applies to their Xenon lamps in this series.

Cheers,

Richard

Found the insert that came with my 4AA SL. No where does it state to use "only " alkalines. However on the back in small print at the bottom it says" Takes 4AA size alkaline batteries. inside the insert under specs it reads Bateries: 4AA size alkaline, and under "Battery replacement" instructions it reads "Replace with 4AA size alkaline batteries..."
Guess that qualifies as reccomended power source? Something to keep in mind for use in future lights.

I have it on good authority that it's possible for the Streamlight 4AA ProPolymer LED to reach 280F inside the case.

On alkalines.

<font size="2" face="Verdana, Arial">You're probably right. I did some testing with mine. I didn't check the internal temperature, but I did make frequent checks of the bezel by an infrared thermometer. What I've found is that heat dissipation is insufficient if the light is left in a static position without any airflow. If you move the light just a little to permit a bit of air flow or a different heat radiation pattern the temperature drops rapidly.

My 3C 10 LED just arrived today, and the instructions (generic for the 2AA, 4AA, and 3C - LED and Xenon) say "Use only alkaline batteries."

I'm not too worried; since it has that ol' UL rating, this is gonna be a work light, and I'll be changing the batteries when I see much drop in brightness (noticeably less than the LGI on center, but with a wider beam, according to my MK I Human Eyeball). Where I prefer lithiums is for that light sitting in the car glove box for years until that dark and stormy night when you need it.

It's been been on for about 5 minutes just now, and doesn't feel warm.

I don't think I'd get too concerned about the heat of the 3C 10LED Streamlight. The LED module is encased in metal, and it is operating off of three cells rather than 4. I don't know, but I doubt if they've included any regulation or stepup circuitry.
