Good luck with high powered lights, a 1MCP spotlight with the red lens will wipe out everyone's night vision. high powered red light makes really no difference compared to a white light if your trying to ruin night vision. However, a single 5mm LED in red is the most super awesome light you can use in the really dark places.
A personal experience as a no0b astronomer going on a trip with another no0b astronomer who thinks he can read star charts with the 1MCP w/ red filter [he brought it thinking he could use it for emergency lighting] and that was the only light he brought. that was a long night and alot of arguments from the senior astronomers. :candle:
I bought some small red balloons and stretched it over the "bezel" area of the Zebralite H50 and it works perfectly! If your camping trip is the type that requires a little hiking and not the drive in types, I'd strongly recommend you have a headlamp. Its better to have one and not use it instead of needing it and not have one.
