I bought this TO50R at The’s GB (using my own money). That was a great price for a very nice rechargeable 20700 flashlight/power bank light. I really like this light but then sold it to my friend. Thought to get my second one but held back because of some technical problems: It’s not waterproof , not even rain proof. A pity, it has nice beam/tint, high CRI, powerful, useful, and excellent UI. Although the mode spacing can be improved, I can live with that.
The LED were soldered nicely and I like it as is. A nice high CRI gift light
I wanted to post a review months ago but totally forgot about it. The light is no longer with me so I don’t have any new pictures to show you the waterproofing problem. I never liked rubber flap to cover charging port and I thought TO50R USB port was sealed, which is not.
The rubber flap is very soft and flexible, should do a good job sealing the port for a while. But we don’t know how long the rubber flap will last. Most popular charger don’t fit 20700/21700 batteries so the owner would rely on the on board charging, and constantly flip-flaping the rubber flap. With a non sealed charging port I would not want to dunk it underwater. The charging port poked from a thin walled window and the only way to make it truly water proof is to completely pot it with epoxy or silicone sealant.
So make sure to carefully secure the rubber flap before any wet-prone activities. A slightly opened flap will suck water after the light gets warm. I tested the light with water droplets dropped near the (opened) port after running the light in turbo until it gets hot. As the light cools down, it sipped all the water droplets (reduced internal air volume) . The next time I ran the light, the water vapor clouded the lens.
The other important thing, especially for those turbo-resetter: inadequate thermal paste and very rough MCPCB could be a problem. Quick lapping should fix the problem. Check below pictures:
- Minimal thermal paste applied
- The MCPCB shelf is not as smooth as other brands
- The MCPCB base is very rough. Fortunately it doesn’t suffered hole flares like Fireflies.
My TO50R engraving was off white with uneven splotchy appearance. But I kinda like it, makes for a used appearance. Hopefully in the future Wuben will use larger radius. The base felt somehow sharp and a light drop to the floor dinged the corner and it couldn’t tail stand as stable as before. The magnet is so strong you can dial an RRT01 without touching
