As with most things being purchased the first thing to do is establish a
price point. While not always true it is common to get what you pay for. A lot of boaters are accustom to paying much more for
boat stuff than what non boaters would expect. While not everyone is aware of it just as there are guys into boats there are also guys into flashlights; and it should not shock anyone they have a presence on the
internet. Here is a
link to the Candlepower site which has lots of information about flashlights, and flashlights that you can attach to your
head.
Some of the products there are stupid expensive and many of them will shock folks by what they are capable of. I have several small flashlights that produce a great deal of light and cost maybe $US50. One is smaller than my little finger and brighter than a six D cell flashlight I have. Also have some
head flashlights. While I do find them useful as others have posted I don't really like that I have to cycle through white dim/medium/bright/super bright; and then do the same with red and blue light.
Sorry about not suggesting a specific solution but if you go to the Candlepower site you will soon learn that just as guys here argue about which is better a
monohull or
multihull guys there argue about which is best just as much.
