Carson RedSight Red LED Flashlight For Reading Astronomy Star Maps and Preserving Night Vision with Two Brightness Settings (SL-33) X-Large

I actually don't think that's it, but it's a good idea. I have used the light before to shine in it from above, no lid, so no glass in the way, to see if there was an isopod at the back and there was one - but yup, once more running like the wind once the light shone on him/her. It's this light. Maybe the issue is that it's LED? I honestly don't know lol, I just bought the cheapest thing with the best reviews...
