ARCHON Dive Light 1200 Lumens Waterproof Diving Flashlight with Power Indicator Narrow Beam and USB Charger Blue Torch for Underwater Lighting

If nothing else, this underwater flashlight can be used to get someone’s attention underwater if you hit it against your tank! That’s a joke, but I love both the color and light emission on this scuba diving flashlight. The price is great as well.

I have tested it a bit underwater and had no issue. The reason I give it 4 stars is because it doesn't seem to have the power one would need for a primary light. I think it's best used as a secondary light on night dives or as a "nice to have" on a day dive if looking into a crevice.

Just completed four daytime dives with this light and I like it very much. Makes a big difference while using a GoPro and filming under ledges and in dark places. Battery lasts a long time.

For a rechargeable battery, it lasted over 3 dives. It’s brightness really lights up the reef. I highly recommend!

The beam is not very narrow, and it's supposed to be "narrow beam." If that's not important to you, it's very bright.

Ran test several times . This light runs less than a hour .don’t waste your money !

We recently took this small dive light to the Atlantic Coast for some shore and boat diving in Palm County Florida. The three settings are HIGH, LOW and STROBE. We tried all three features and realized that this light is well built, long lasting and compact; in short, it's a perfect light for recreational diving. The battery lasted over the course of one night dive and several day dives where we would use the light to see inside coral formations, under reef ledges and inside various nooks and crannies inside artificial reefs such as intentionally sunk ships.We didn't utilize the strobe feature. However, it is a very useful mode for marking an anchor line up to your dive boat or for marking your exit point on shore while night diving.The lanyard is a bit long, so we put a knot in it to take up some scope. The internal compartment is sealed with not one but two O rings (the standard for good dive lights).There is a spot beam in the center and a wider broad beam to illuminate the area around the spot beam. The price of this product is attractive so having two of these lights in your dive kit (a primary and a backup) is within your grasp.A nice addition for this light would be a case to hold the light, lanyard, charging cable and spare O rings. Other than that, I am impressed with this product.

I really like the look and feel of this flashlight. Great size and weight to it. The only issue was that the battery was dead on arrival. I charged it up but never took a charge. I had to purchase an 18650 battery to fully review it. Once it worked, it was good. Very bright and easily pocketable. I use it for work and is perfect for my work needs.
