Since I fell over new flower pots in back of the house I grew up in, I always carry a red Inova Microlight clipped to my shirt pocket. I got the red before white leds came out and have kept it, as I like it better for a small light than white.
I usually carry at least one other, sometimes button and sometimes full size. Now that is an unusually fine, one mode SK58 from Price Angels. I have tried to order two more of it, but I received a 18650 piece of junk from them, so maybe the order has been confused.
More detail of the knurling and finish is visible if you view the image directly. It is attached to my key chain.
Sometimes I just carry two or three button cell lights.
For a little more light, I have two AA XM-L lights, an SK68 with a warm white XM-L2 and a Z8. For more than that, I much like my Sipik SK73, unless I expect to have it on a long time in high mode in which case I carry my Raysoon TD398 for better cooling.
For a while I had a 3-Mode AA Zoom 3-mode Zoom AA/1450 EXPIRED ! "Black" $1.99 Max 3ea clipped in my shirt pocket like a pen, but I don’t like it esthetically. I have carried a Smiling Shark SS8043 TIR but prefer zoomies. The Raysoon is the only one of these that cost over $20. and that is because it came with a head band.
