get it while you can for cave diving primary

By Ig S.

 -  Philadelphia, PA, US

I tried this as a rental and was surprised how good it was. Its very bright, and I don't think you'll miss the 300 lumen difference between the now top TL4800, both of which is a tad too bright for regular use in cave diving, and the 2 or 3 work very well, and the 4th level too is decent, and surprising~ 20 hours for a primary. I probably will never kill my light in a long dive since I can downgrade the brightness when the power indicator shows I'm running low, and extend the bat life even...

New to Bigblue in the 2016 light line-up is the TL4500P. This light is a self-contained technical light that pumps out a stunning 4500 lumen narrow beam. The TL4500P has a compact body style, uses a reliable push-button switching mechanism, a battery indicator on the light itself, and your choice of 4 power levels and an SOS function. As a self-contained light, it uses a self-contained 4 x 18650 lithium ion rechargeable battery pack and comes with a charger. The battery pack is removable for easy replacement with an optional spare fully charged battery between dives. The TL4500P also comes with a reinforced Goodman-style glove, lanyard and an aluminum lantern-style handle, which makes this light a versatile option for any diver wanting the extreme light output needed in demanding conditions.

The TL4500P deep penetrating narrower beam angle at 10° degrees will cut through the murkiest waters. The lights 4 x XML LED's provide 450 lumens of brightness at level-l, 1,125 lumens of brightness at level-ll, 2,250 lumens of brightness at level-lll and 4,500 lumens of brightness at level-lV with a color temperature of 6500K. The lights burn time at level-l is 20-hours, at level-II is 8-hours, at level-III is 4-hours and at level-IV is 2-hours. Built to last the light is manufactured from aluminum alloy that is anti-corrosion anodized, is sealed by a double O-ring providing a depth rating to 330' (100 meters). The light head has a tempered optical glass front lens. This handheld light measures (L x Dia.) 5.92" x 2.83" (150.3mm x 72mm), weighs 21 oz. (596 g) with battery, and is negatively buoyant by -7.83 oz. (-222 g).

get it while you can for cave diving primary

By Ig S.

from Philadelphia, PA, US

I tried this as a rental and was surprised how good it was. Its very bright, and I don't think you'll miss the 300 lumen difference between the now top TL4800, both of which is a tad too bright for regular use in cave diving, and the 2 or 3 work very well, and the 4th level too is decent, and surprising~ 20 hours for a primary. I probably will never kill my light in a long dive since I can downgrade the brightness when the power indicator shows I'm running low, and extend the bat life even more. In burn tests, the light did not cut off when flashing red appeared at 2.5 hours, but burned non stop to 6 hours getting dimmer, I cut it off myself, I found voltage down to 10.8V for 4 cell pack, a little on the extreme side for lithium health. The power switch adjust the drain and hence the lumens, but the light will burn regardless. I measured when each setting as 3.3A, 1.3, 0.7 and 0.4 draw on fresh batteries and burn time for lumens matches the calculated consumption for 3400mAh cells. The lumens are not consistently for a setting, but slowly drops as the power drops. A bit heavy for wrist mount only, but canister lights are notorious for flooding if damage the cord in an accident. No such issue here, and I've never flooded hand held backups over 20 years of diving. So weight is a good trade off for reliability. Use the lanyard as a safety on my wrist. The Goodman glove it comes with does not provide reliable support for the light for technical use, as its held only by velcro and you can't tighten it enough to be solid. You'll have to get the metal handle for $45 more, get the slim fit, the regular is a bit big.

Questions & Answers

Questions about this item:

Shopper  Does this have a battery you can take out so you can put another in while you charge one? Thanks.
MARK E  Yes the batt. comes out easily. You put on charger that is incld. You will need to buy 2nd batt as it only comes with 1 batt. (It is a good, solidly built, bright light, multiple brightness settings is really nice).
John T  Yes, you can remove the battery. This light is extremely bright. I use it for cave diving. It is so bright I usually only use it on the 2nd lowest setting so the battery last a long time. Great price too.
Marvin G  Yes, it has a battery pack. You'd have to buy another battery pack to swap them while one charges.
