If you’re going to get solar lights for an emergency, go to Home Depot and get the 55 lumen Hampton Bay solar spotlights that cost under $8. They take a removable 1000 mAh 18500 cell. 55 lumens will be way more useful than 5-10 and you can probably take the battery out and use it in a lot of lights that have a 3aaa battery carrier.You can go to walmart and buy the solar powered pathway lights that use 1 AA battery for $3 each.
Around 5 to 10 lumens, (so buy a few of them)
Not sure if anyone has mentioned it, but if you’re not completely attached to the AA/AAA, the paklite (9voltlight.com) using a lithium battery lasts nigh on forever and will probably give you the amount of light you need. I have one for a night light for my daughter when traveling and it’s got weeks on it with no noticeable drop in brightness. As a bonus, they make a higher CRI version that looks a lot nicer (what I bought). An added bonus: those 9v “dead” batteries from the smoke detectors will run for quite some time when run on low in a Pak-Light. They are GREAT for emergency kits.Looking for a reliable budget AA- or AAA led light with longest runtime on low setting...doesnt need to have super bright capabilities. Probably 30 lumens or less. 1 or 2 lumens may be a bit to weak to see in the tornado shelter. Ty
I like the Streamlight Propolymer 4AA but i'm reluctant buying it. If one led goes bad the others will go bad also.The Streamlight Propolymer 4AA should be pretty cheap. It's rated at 67 lumens for 155 hours.
They also make a 3AA lantern that might be more convenient if you are looking for area lighting.
A bit off main topic as OP is looking for single-cell AA or AAA, as noted 18500 fits in some (but not all, depends on holder) low-cost 3AAA flashlights; some even take 18650. However if goal is short-term cell wide availability without need to recharge, primary AA/AAA may be the best choice. Regular OTS sources of 18500 (LiFePO4) such as HD are a bit pricey.If you’re going to get solar lights for an emergency, go to Home Depot and get the 55 lumen Hampton Bay solar spotlights that cost under $8.

I'm sure Cree and SST are not the only ones who make LEDs with high efficacies, and at least some "cheap" LEDs from vendors we may not have heard of can do a decent job these days. In another thread I pointed to Samsung LED giving up to 220 lumens/W at 0.2W .I am pretty sure that those 3mm leds often found in cheap lights are not nearly as efficient as a decent (Cree or SST) led.
I had a 24 x 3mm satellite lantern that ran on 4 AA batteries. It was surprisingly inefficient compared to other lights I have.
I don't know if there are different quality COB lights, but I think generally speaking they are nearly as efficient as an XML or XML2 led.

If you’re talking about the old 7 l.e.d. light, you’re right. Had that light maybe a decade or more ago. L.e.d.s didn’t last past the second or third set of alkaline batteries. One of the worst lights I ever had. Newer lights use better l.e.d.s that are made to take the heat, run efficiently, and use circuitry that protects against heat, high voltage, and reverse polarity. Don’t get a light that uses old 5mm l.e.d.s and maybe a resistor.I like the Streamlight Propolymer 4AA but i'm reluctant buying it. If one led goes bad the others will go bad also.
