Review on 🌊 Diving Flashlight, Waterproof Diving Light with Max 2000 Lumens, Rechargeable Dive Flashlight featuring Cree XHP35 HD LED, 4 Modes Scuba LED Flashlight for 150M Underwater, Includes 1x 18650 Battery and Charger by Mike Starling

The price is not bad. Calling it a 2000 lumen light is a bit disingenuous as full brightness lasts around 30 seconds on a full charge. The runtime diagram deviates greatly. I only had a few minutes or less on the turbo and the high was at 10 minutes before switching to medium and then low. The total running time from high speed was 60-75 minutes, depending on the battery. This is definitely NOT a watch as advertised. The included battery is not that great. I found that larger capacity batteries lasted a bit longer after they came out. The supplied charger is annoying and really not worth it. I bought a much better dual battery charger for about $22 that works much better. It gets very hot out of the water so don't plan on using the turbo or staying out of the water for too long. Cool running under water. There was no inrush during the dive to 70 feet.
