Many thanks to all. I can't help myself - I ordered a ULTRAFIRE. At 18 bucks, I've got to test drive one.

Thats got 2 18650mah batteries, those should last you a while on a single charge. I just ordered it to test out.

Keep the light and throw the batteries away. Ultrafire batteries are rebuilt laptop cells. Spend another 20 bucks and buy some Panasonic cells ncr18650b.

ZK-315, that pic is a C-8, many distr. carry that light for dif. prices, and dif. XML-leds. I have around 15 led lights, my C-8 is an Ultrafire, it came with an XML-T6/R2-U2 bin led, one dual battery charger, and one 3000 mah lithium battery. $15 on E-bay. Hard to beat for price. I have a couple of Streamlights for my night hunting and others. Research online, E-bay and many others, read light reviews and forums. You can get some helpful advise. Talk to people that have the lights and use them. Lots of over priced hype out there. Been doing this for a few years now. Thats my two..

I'm a flashlight junkie and have lots of them. I've had streamlights and they are great lights. However, I recently bought one off eBay and I love it. 2200 lumen and less than $20. After I used the first one for a while I ordered 3 more of them. Here's a link to it for $17.98 with free shipping. http://www.ebay.com/itm/2200LM-UltraFire...=item20e92d20b0

I bought this light based on the recommendation here and had to put it to the test last night tracking a deer. I expected a lot more for it to be 2200 lumens, it wasnt any better than my Bushnell 265lumens light that I picked up from Wal-Mart.

Question: Could it be the Ultrafire batteries causing this?

Sorry random question... Whats the purpose of a red tinted plastic cover/ glass on a flashlight? What does the red do? Thanks

If it isn't any better than your bushnell something is wrong for sure. My buddy has a streamlight and I can turn mine on over the top of his and you can't even tell his is on. Did you charge it for 24 hours first?

I charged both batteries, but to be honest they have sat in my bag for a week or so since the charge. I probably should have charged both of them the night before, but yesterdays trip was a spur of the moment thing.

Also make sure you have it on high. If you push the power button multiple times it changes the power level. I use mine on low until I really need lots of light because low saves battery power.

Small stream light. I have several and they are awesome.

Didnt realize that. If I push multiple times it starts flashing but didnt notice any change in brightness.

I got the flashlight out today and noticed it does have a low/medium/high setting. I was definitely on high. Could it be the Ultrafire batteries? If so, what do u recommend I replace them with?
