Comments about Princeton Tec, Tec-40:

I bought this light to replace a Techna 4 light and it is no where close to providing useful light. I bought one for all 4 members of my family that dives and none of us will probably use it to dive. I use it during day dives to illuminate holes and see actual colors. I needed to be about 6 inches away for any light effect. Very disappointed, but it will be a good light around the house.

I Love this little light! You really should get this one!!! My son (who dives) gave me my 1st one and it throws a beam like nothing else! The bulb lasted almost 3 years, even though I use it a couple of times a week, when it was time to order one I also bought another light for our sailboat.

I LOVE this powerful little light! My son (who dives) gave me my first light and it throws a beam like nothing else on the market, when I needed to buy a new bulb I found LeisurePro and got an extra one for our sail boat.

because of the twist on and off switch, light may come on when diving deep due to pressure on the lens.

Purchased as a back-up for my rescue gear, not a great beam. Will only utilize for recreational diving.
