Not to worry, your bees will not go blind.

I did a quick google, and found that Amazon is selling a "2-Pack Defiant
High Power Tactical LED Flashlight, 130 lumens".  If they are only 130
lumens, then you don't have to worry - a standard-issue 3-D-Cell Maglite
flashlight with a non-LED bulb puts out about 170 lumens, and everyone has
used those around bees for decades.

Just off the top of my head (don't blame me, the head does the math on its
own), I doubt the "130 lumens" number is anything but bluster, as this would
imply that you have a roughly 1-watt flashlight.  If that were true, you
would burn through a set of AA batteries in about 2 1/2 hours, as the best
alkaline AA batteries put out about 2.6 Watt-Hours, and 3 of them in series
give you a 2.6 Watt-Hour 3.6 Volt power supply.  Other types of batteries
will last significantly shorter periods, except for NiMH, which perform
about the same as alkaline.

I can't imagine a flashlight that eats its batteries in 2.5 hours would sell
very well.
Betcha the batteries last much longer, and LEDs don't run on magic.
