Petzl climbing lamps use AA. But we add our own red filter.

If I'm reading this correctly, it seems you've missed that part about dim.

I have red lights. Ok. Basically the red lense makes them... dim... which makes them effective. I'd change my red for soft yellow if I could. These came with a nice chrome plated plastic bezel. They're LED trailer light.

Don1500--

Something you might consider: Before I installed colored LED arrays in our light fittings I carried a few rolls of "Tailight Tape" from Discount Auti and as preparation for night running would apply that to the lenses of lights that migh be activated at night by unthinking crew. For the round bulkhead mounted bell shaped reading lamps, I found that the plastic covers from 3-ball cans of Tennis Balls fit over the ends prefectly. The centers could be cut out and tail light tape applied, to the inside and outside of the covers to form a good bond and "dim down" the lights. Tail light tape is also available in several colors--Red, Yellow etc. so you could try these to determine what works for you.

FWIW...

The Gerber Meridian Headlamp, made for hunters, has separate red, green (for not spooking game) and white lamps and uses AA batteries.

Whenever I am confronted with a technical question pertaining to sailing I turn to my Pirate Dctionary for answers. This reference assures me that during sea battles, those sailors designated to shuttle munitions etc between the deck and the hold would wear a patch over one eye, thus preserving night vision in that eye. When the sailor would run below he would flip up the patch, then flip it down again when he returned on deck.
Probably not as usefull as a dim light in our context of sailing at night, but it would be an excuse to wear an eyepatch while on passage.

The old wooden warships were notoriously poorly lighted below decks--for obvious reasons, one did not want lanterns with burning candles hanging about when in battle. About the only light was that which filtered down through gratings in the decks above, and a single dim candle lantern in the bulkhead to the magazine where the master gunner passed charges to the ship's boys. Ship's boys, therefore, needed at least one eye accustomed to the deep gloom which prevailed below along the orlop and in the hold where the shot lockers and magazines were.
