## Description

desertcart.com: TrustFire DF50 Scuba Diving Light, 6500 Lumens Video Camera Photography Dive LED Flashlight, USB Rechargeable Torch, 70M Underwater, Super Bright, with Violet Red White Lights : Electronics

Review: Impressive Video Lights - I have 2 of these lights on a camera rig, with around 50 dives on them now. They're great lights, and for a good price. They have plenty of power for daytime videography, and at night they're even better. Video lights don't have a hot spot, so they illuminate the area very naturally. I don't find my self reaching for a dive torch unless I need more reach at night (e.g. when you see something move in the distance). If you're doing still photography, you'd be better off with strobes, but these still work just fine, and are far cheaper than a strobe set up. Durability is great. I soak them, charge batteries and grease O rings after every dive day. The ball mount appears to be hardened carbon steel, which isn't great as they're corroding where they meet the aluminum housing. I installed mine with locktite as a slipping ball mount is a real pain, but with the corrosion they're never coming out again anyway. I don't even want to disturb them to clean the corrosion, they're installed, they don't slip, they're staying there. Complaints about stripped ball mount sockets are likely due to over torque issues. Take it easy with the wrench and use some locktite if you're concerned about them backing out (as I was). The mode/power button works well. It remembers the last mode you were on, and turns on the that mode when next activated. It also flashes intermittently to indicate battery level (green, yellow, red, flashing red) which is handy as charging these batteries is a real hassle. It has a lock mode to prevent accidental activation for some reason, the button is so firm and requires a long press to turn on anyway, so its not necessary. If you think the light is dead, you might have activated it accidently, just double click the power button to turn lock mode on and off.
Review: They died after 2 years of storage - I purchased two lights in August and September 2021. I have used one of them no more than 5 times, the other I have used only once. I then left them in storage for two years as I had no time to dive at all. They were stored in the protective cases they came with, with batteries disconnected. I tried to use them last weekend (January 2024) and none of them switched on. I have charged the batteries (one was continuous green when connected, and the other one was blinking as charging until it got continuous green too.) I have sent an email to Trustfire, will wait and see what they say. When the light work they give enormous amount of light (I film cave diving movies so no amount of light is too much). I really wish I can make them work again.

### ⭐ They died after 2 years of storage

### ⭐⭐⭐⭐⭐ Great light, but not watertight! (but see the update)
*by E***C on October 4, 2022*

I received the flashlight on September 7th and took it to a field trip in the Caribbean. The light performed great, it is very bright and the battery last forever, as promoted. However, I detected some condensation on the front glass. I checked the battery part and it was dry, I closed it again (after applying some silicon), hoping the "problem" was over, but the condensation remained. After coming back, I put the flashlight in fresh water for a couple of hours and when I checked again I saw water inside the front glass. I opened the battery chamber again and it was dry. After shaking the front part of the flashlight, (salt) water dripped out. Of course, the light is broken now. I wrote to the seller, but they have not replied to the guarantee. I hope they do since it is not a cheap flashlight. Evidently, it is a manufacturing problem, since the glass is intact and the body of the flashlight is not compromised in any way. Update: TrustFire sent a brand new light head. It is working very fine so far. Great customer service. Congratulations.
