I have been using this model LED headlamp each day for 6 months, so far, and used it for a month of cruising. I also use it every day (at home).
I have not had a
single problem.
It is VERY bright on one mode, but I most often use it on Red Light mode.
Is Red Light Mode important?
The effect of using white versus red light on night vision (such as when at sea at night) is a subject you can
research. Traditionally, a red light has been used at sea to protect "night vision." There are some tradeoffs using red light. I use it because it is a much lower light level (dimmer) and THAT is what is important to maintaining night vision such as when on
deck. The lower (dimmer) red light is also not as bothersome to others on
deck or below in the
cabin. The red light is enough for you to see where you need to go, or for operating simple things or finding things in a dark space or
boat. I detest those folks who use a VERY bright white light and point it in the face of others (especially common with headlamps but also happens with handheld lights), essentially blinding them. So, for me, the Red Light Mode is very useful (I use it every night) and preferable in most cases.
I like these features:
1. Headlamp
2. Bright CREE LED lamp
3. Three AAA
batteries (I use rechargeable AAA)
4. RED mode (I use this every night on a
boat, and even at home)
5.
Water Resistance (it has a small rubber
gasket around the hatch) IPX6
6. Strobe Mode (if you become a MOB)
7.
Price. (Can be found for about $7 or 3 for $15)
8. Adjustable angle for light when worn on
head
9. Easily fits in a pocket of a jacket or pants.
By itself, the unit is small and light weight, something I think important when on one's
head.
While you can
purchase these as
single units, this link below is for 3 units (with batteries), and gets the price per unit low.

Beware: Some very similar looking headlamps are:
A. More expensive
B. Heavier
C. Do not have the Red Light mode
E. Lower brightness.
F. Not as
water resistant (no rubber gasket)
Hope that helps.
