I've been using a standard Mag Light for years, but I like the idea of having something fairly inexpensive w/ red or green LEDs for better contrast when finding stuff in the back of the car or boat. Any recommendations?
TL;DR- jgray, start out with the Ultrafire 502b with battery, charger and maybe order the filters you need. It's no Surefire, Nitecore, Fenix or Streamlight, but socks knocked off nonetheless.
That's one of the features of the Nitecore SRT7. It has Red/Green/Blue LEDs integrated into the head along with the primary emitter. There are three LEDs that each LED outputs all three colors. The "smart selector ring" along with the standby mode is what really sets this one apart. You don't have to cycle through modes to get to what you need. It's not cheap, but I don't think there's anything currently on the market
at any price that's in the same league as this beast. Since you're used to Maglites, any Goinggear.com review on Youtube will give you a reference as their control light is a Maglite.
My suggestion as a very good starting point that won't break the bank is to order an Ultrafire 502B with XML-T6 emitter from Amazon or eBay, with 18650 battery and charger. Know that the lumen ratings will be grossly exaggerated, but will still knock your socks off if you're coming from a Maglite. You can also order slip on filters for the head to get your red/green contrast. Basically for $25 or so, you're into these next generation lights.
I haven't ordered anything from eBay in years and took a leap of faith with the sellers Andrew-Amanda.com out of Cary, NC. Fantastic service and will order any lights that strike my fancy from them from now on. Got a heck of a deal on the Nitecore SRT7, the Nitecore i4 charger and a Nitecore 3100mA battery for $109 shipped, no tax. Kinda made buddies with Andrew, so pretty sure anyone that wants that package, we can get it at that price. I have a bunch of 18650 chargers but this one is again, one of the next generation units. It charges anything rechargeable, automatically detects the battery chemistry and capacity and whatever else. No need for my big box of chargers.
On batteries: My Surefire eats $12 in CR123A (non rechargeable) batteries in about 10 minutes and is about 1/10th the output of the Nitecore. With the latest generation batteries and emitters, we're talking 10,000 times the performance and longevity over older generation technology. That's why I'm so goobered out over this stuff. It's Moore's Law in action.
The latest Tesla Model S (electric car) runs 6,000 Panasonic 18650 batteries in an array. Your old laptop probably runs on Panasonic or Sony 18650 batteries. I recently cracked open three old battery packs from Dell laptops. Each laptop battery held 12 Panasonic 2250 mAh batteries. These are expensive and very high quality Japanese-made batteries. Better than most 18650s you'll find as sold for flashlights. These are probably equivalent to the exaggerated rating on Chinese batteries of 3400 mAh. Anyway, about $500 in batteries from three old laptops (I almost never used the laptop on battery power alone). Put this in perspective of the equivalent in Surefire CR123A "primaries", and this would be like, I don't know, $10k in batteries that the US military still sources from Surefire? Multiply that by the useful output and we're spending like $100k for freaking light for our boys that could cost $100, not even considering the flashlight host cost of 10x what it should be? I don't get it. Actually I do understand how that happens, but the root why is frustrating. Told myself I wouldn't do it tonight but I did anyway.
My next light will be the Nitecore TM26. Now I just need a real reason to buy it. Would probably need to own a farm to justify that.
I'mma pull a Beuller on Jarrod to say you have the means and I highly recommend picking one up. The Nitecore Tiny Monster 26...
