500 lumen multi-mode 3C LED Feit flashlight two-pack for $25 @ Costco B&M (6x Duracell C's included)

Quote from Ray97 : Thanks for the pictures. It looks small and bright, I might grab these also for my car and my dads. The new defiant 493 is too big to be put in a car imo and I would put the old 550 in my car but I only got one of those. Rep'd for the pics

how can you prevent the battery leaks in the flashlight if you put the light in your car?

nice flashlight

Dang I gotta go to a store! Lol!! I want one and am lazy to ask my sister in lawn to come

Batteries will lose power in storage regardless of location. The main difference is that batteries may lose power more quickly due to heat in a car, and the car has less space to stash spare batteries. Minimize battery leakage by keeping the batteries in the glove compartment or under insulation in the trunk, or in a Coleman-style cooler if you happen to just keep one in your car. You will still likely have to check the batteries more frequently, however.

For alkalines, use a compatible battery charge tester like this [amazon.com] or a multimeter and get a feel for how low the voltage gets before your flashlight get too weak. For anything else, you'll just need to feel out how your flashlight responds to a battery that's near empty, based on the beam (but some LED flashlights use regulators that keep the light even until just before the battery is too weak, so there's less warning, if any).

If you value your time more than your money, you can also just decide on a regular schedule for how often you just switch out the batteries. You can always just label the batteries for home-only use and use them before using totally new batteries (try to keep the used batteries matched if possible). Alternately, you can just make a habit of carrying batteries in a "driving bag" that goes indoors with you when you're not driving.

You can also do any of the above with rechargeables and just rotate and top them up on a reasonable schedule. If you use a smart charger you can even be warned of failed batteries or keep track of the maximum measured capacity over the battery's lifetime.

If you want more suggestions, it might be wise to find an emergency first responder and ask them if they keep their flashlights in the car, how hot it gets in the car, and how they handle the battery situation. I would not be surprised if they told you they just keep 3-4 shifts' worth and just rotate out as needed. They would use their lights more frequently though, so they're probably not getting the entire stock discharging at the same rate, and new sets are frequently being swapped in.

thx for the details write up.

think i get thanks op and az for pics. repp

REP all around to op, pictures and battery suggestions....Nice light too for the price.
I'm guessing here..... this is made by the Co. that flashaholic hate?

Feit has gotten some flak about its LED bulb value in the past, but most of it is from the general LED bulb vs. CFL bulb value discussion. I only posted this since the Defiant was pretty popular and I thought this was a nice alternative deal for some people, and the Feit lights seemed to perform about as well as the Defiant in the high lumens/widest angle mode.

If these flashlights do crap out, Costco return policy helps just in case Feit's warranty fails.

Can this be used to mount on a bike? Where can I get a mount for this?

These don't happen to be submersible/waterproof do they?

Just to share i just got a really good flashlight off ebay for less than $16. It uses the Cree T6 LED and is super bright. It has the option to run on 4-AAA, or one 18650, or one 26650 li-ion. Right now the 26650 is not a cheap option but I hope it will be in the future, the four AAA's are very cheap and will last me a while. The seller got it to me in about 2 weeks, which is real fast from china. The wide beam is very impressive, the narrow show's the LED's die, similar to what the OP posted.

I got this flashlight because of the T6 LED and the fact that it will take 4-AAA's, there are several T6 versions out there that only use 3-AAA's and that odd number is annoying IMO. I would also like to use 26650's when the price comes down.

What do you think the lumen difference is using AAA batteries?

Look in eBay, search for "bike light holder".
Pick the one that fits your bike handlebar's and torchlight's diameters.
I bought a couple from China and work pretty well. I think I paid last year around $5 shipped.

Caution against ebay, meritline, or any other discount flashlights. I've been burned a few times - they work great for a short while, then something stupid breaks like the switch and you're left with a nice battery holder.

This is when Costco really shines - if it quits, take it back. Either that or buy a high quality light like a Fenix.
