    Any Boruit V1 Users on here?

    Hi, Just picked up a Boruit V1 for EDC. I like the size and weight. There's enough flood to easily walk as well. This fits in the small pocket on your jeans, and I find I can forget I'm carrying, which is what I wanted. GTID doesn't last that long, but it's better than nothing. Manual says the...

    Is it possible to melt plastic optics while overdriving a LED?

    Thank you for the replies. People that do report melted optics seem to run them for multiple minutes on >High or Turbo. It will be fun to find out. Regards.

    Is it possible to melt plastic optics while overdriving a LED?

    Hi, Quick question; I'm planning a custom build that will run 10A through a Cree XHP70.2 - for short periods - 5 seconds max. That's about 65W. Properly heatsinked, an XHP70.2 will take 20A (design limit is 4.8A), but I'm wondering about the optic in front of it. Has anyone ever heard of LED...

    R50 Pro UI questions - Can you adjust the lumens output for different modes?

    Hello mortuus, Thanks for the reply. That's a shame. The charging system on this is a big step forward. Many of these sigle cell big emitter lights run in near direct drive mode on turbo, so having a fully charged cell is a must if you want full potential at turn on. Running even a half...

    R50 Pro UI questions - Can you adjust the lumens output for different modes?

    Hello, Looking to buy a 3k lumens rechargeable flashlight in the 26650 format. I don't need full output for more than 15 seconds at a time, just long enough to quickly scan an area, then off. It's nice to see someone has finally realised taking a flashlight to bits in order to charge it is so...

    Re: F\S SST90 Mag2C (40Watts) Hello bxstylez. This light uses a switch mode buck converter, not a linear converter. At 9A, an SST90 required approximately 3.7V. Ohms law gives us 9x3.7= 33.3W at the LED. The converter isn't 100% efficient. Assume 80% worst case (this figure is typical)...

    Re: F\S SST90 Mag2C (40Watts) OK, Here are some outdoor beam shots I took this evening. Camera set to Manual mode, fixed aperture and exposure. 1. Cree R5 @1A 2. Tri Seoul P4 @ 1A each. 3. SST90 @9A The SST90 just blows the rest away. It's an insane amount of light from such a small...

    Re: F\S SST90 Mag2C (40Watts) I'm surprised too. Must be the economy......... Would make more sense to break the light for parts than drop the price any further.
