It's impressively bright. I bought it for the red light, and am somewhat disappointed that I must switch to white light before turning it off, even if it has been on for a while. Ideally I would have preferred all red lights. I bought this for use in the cockpit when flying at night. I can pivot it to read a chart in my lap handsfree.
Pros: impressively bright red light, directional
Cons: must flip to white lights to turn off
