bought a tusa tl-240 halogen light yesterday, uses 4 c batteries. a friend of mine has been using one for close to a year now, with no problems, which is what prompted me me to get it.
initial impression.. wow, a lot better than the other dive light i used (a very cheap model, no name brand actually, one O ring, twist the top down to turn it on, used 2 d sized batteries.) The tusa fits the hand pretty decent
(i wont lie and say its a perfect fit, because i shoot the gun with my left hand, and the light was designed to be held with a left hand, so its slightly out of shape in my right hand - it is a very good fit in my left hand though)
feels balanced underwater, has a very good wrist strap, and, will last about 8 hours with the xenon bulb, which i used instead of the halogen (dont need all that blinding light for water 10 feet deep) it is waterproof up to 50 meters, which is overkill for what i do at night (or even during the day!)
complaints about it.
the safety on the light switch is a bit rough on my finger.. well actually not a complaint in the water, because i cant feel it through my gloves, but when im on land, its a bit of a nuisance, but nothing that a light sandpapering wont fix!
its a bit big to mount on my cave gun, most of the caves i shoot stuff in are relatively small in the entrance, and the light would get banged up really bad.
umm..yea thats it, all in all, a great light, i payed $80 bds for it at a local dive shop, thats $40 US, im not sure what they would sell for in other places, but if u take off shipping and the local dive shops profit, i'd say its a pretty decent price for what i got.
