Waterproof 1000 Lumens LED Diving Flashlight UnderWater 150m Super Bright LED Scuba Light, 9 Degrees Narrow-angle Beam Diving Safety Light Night Dive Torch

I will first start out by saying this is a 5 star product. For the price, you really can't go wrong. But I wanted this review to be more a comparison than another product rave, as it appears there are enough of those already. I'm going to compare the SecurityIng 1000 Lumen XM-L2 LED(SecIng) to the UK SL4 eLED L1(UK). I was searching for a primary dive light in the $60 range, as I typically dive during the day, and narrowed my search to these two items. Both my girlfriend and I needed lights, so I thought I'd buy both and we'd decide among ourselves which we liked better.Light Output:The SecIng is advertised at 1000 lumens and the UK at 400 lumens. I don't have a light meter, but I can tell you that both having a new set of batteries, the SecIng is brighter than the UK. I've posted a picture of both lights side by side in a dark room. It's interesting, in the picture the SecIng looks quite a bit brighter than the UK, but in real life, the difference is not near as noticeable. If I had to guess, assuming the UK is truly 400 lumen, I'd put the SecIng at 600. Also of note, is that the light from the SecIng is whiter and bluer. Both are very pleasant and have that daylight LED look, but the UK has an ever so slight yellow tint to it, when viewed side by side to the SecIng. Winner - SecIngBuild Quality:Both items are built very well. I'd almost call this a draw. The SecIng feels like a tank, like it could be used as a weapon if necessary. The UK is built with high quality plastic and I particularly like the rubber coated lens assembly. In the SecIng's favor, is the fact that it's lens is made from 5mm glass, while the UK's lens is made from plastic. This is particularly good when you consider that both these lights will be getting tossed around in a dive bag and the glass will do a better job avoiding scratches. I also like that the SecIng is waterproofed by 3 heavy duty o-rings(and it comes with spares) whereas the UK only has one and no spares. Winner - TieErgonomics:Ergonomics is where the UK has, in my opinion, the clear advantage. The SecIng weights 507g(with batteries) and displaces 175ml of water. This means that when diving, the SecIng weights 332g, just shy of 3/4 of a lb, underwater! The UK is much closer to neutral, weighing in at 443g and displacing 225ml of water. This means that underwater the UK is a featherweight at 218g or just shy of 1/2 lb. I also like the UK's one handed operation. I hold it with the switch on top, and toggle with my thumb, very nice. The SecIng is a bit more awkward, as it requires two hands to operate. That could get annoying if it were being switched on and off frequently.Conclusion:You can't go wrong with either product. If I absolutely had to pick, given the same price I'd probably give the nod to the UK, just for it's superior ergonomics. However, considering the SecIng is currently $15 less, I'd pick it.

Great light, nice and bright. But runs out of battery pretty fast.

SecurityIng Waterproof 1000 Lumens XM-L2 LED Diving Flashlight UnderWater 150 Meters Depth Bright LED Lighting Lamp Dive Lights Torch for Diving Flashlight arrived in good condition. It was tested with two18650 batteries. With the batteries, the 26650 did not work. I tried it several times, but it worked ONLY with 18650 batteries. The kit did not have an adapter-insert for 18650 batteries. After fully charging new batteries 18650 is no longer on. It is dead. I think that this flashlight is not designed for 18650/26650 batteries, as written in the instructions. Use C batteries only! The instruction is not correct. The LED burns out from excessive voltage. As a result, the working time of the new flashlight was one minute. I'm disappointed because of the time and money spent. And how to get them back now? The flashlight was spoiled before my trip to dive safari. It was not in the water. Perhaps this is for the best, otherwise I would have remained without the light. But my "SecurityIng Wide 120 Scuba Diving Photography Video Flashlight 1500LM" works great.psThe supplier reported that the instructions were incorrect. The flashlight works exclusively with type C batteries. The flashlight has been replaced.

This is the same model as my first dive light which I bought for over $100 from diverightinscuba. After 10 years and 300 dives, my light failed last month. I'm happy with this replacement and hopefully it'll last me another 10 years.

Ok let me first say that I've been night diving for 20 years and have had a lot of dive lights, from the old uk's to the king pelicans. If you purchased this light, you made the right decision! The first time I used this, it blew me away with how bright it was for just a c3 battery flash light! We just went spearfishing at night 2 days ago and my dive partners had the uk eled 8 c battery flashlight and my light was just as bright as theirs ! My dive partner willie was speechless! The very next day he ordered one for himself and I ordered me another one too lol! People take it from me, I'm a Hawaiian that night dives for fish about 4 to 5 times a month and these lights are one of the best buys you will ever make in your life. If you read any reviews that were bad, in my opinion they just did not know what they were doing lol. These were also the longest lasting flashlights I've ever purchased. After 3 to 4 hrs of diving, the light was still bright and white! While my friends Uk Eled 8 c flashlight had a yellow tinge to it! I recommend this to any seriouse night divers out there!

Do not use lithium batteries!!!!! The manufacturer's instructions specifically say that you can use 2 types of lithium batteries with this, 18650 and 26650. Do not under any circumstances use either lithium because it will fry the LED in about 2 seconds. The light is outstanding and works well and is a great value as a primary dive light but if you use only standard C batteries. It's incredibly bright and well made and performs better than other dive lights costing 10 times as much with the same number of lumens. The photo from the instructions clearly stays 3 different types of batteries can be used but the 26650 batteries fried the LED immediately when it was turned on on 2 separate flashlights. Although it's clearly an instruction problem, the light itself is sound. I did not return the 2 lights, I replaced them

This diving light is one of the most practical, the batteries are easily available, it uses type c and double A, and it has good lighting.

Very bright really solid and durable.Can you recommend batteries to use with this light?? I ordered rechargeable ones but they are loose in the flashlight so it turns off when tipped. I have attached a pic of the batteries I purchased.

水中での電源の入り切りも楽で使いやすいです

Nice equipment, feels good in your hand, very bright, looks like it’s well built. Time will tell.

二回目の使用でつきません。とくに、水没などはなく、電池もいきてますが、、、、と申告したところ、迅速な対応で交換していただきました。ありがとうございます。

I bought this light for scuba diving. Its just not bright enough under water and its really big and clunky. Its waterproof and didn't flood, but I don't use it for diving anymore. Spend the extra money and buy a light from your local dive shop.
