    Lumintop BLF GTvn - Best Reflector Thrower?

    Re: Lumintop GTvn - Best Reflector Thrower? Ohhhhhhhh okay that makes sense. But figuring out the different luminous intensities of an LED in every single decision sounds awfully hard to do with just an LED spec sheet or even a measuring tool. After you get that measurement I’m assuming you...

    Lumintop BLF GTvn - Best Reflector Thrower?

    Re: Lumintop GTvn - Best Reflector Thrower? Yeah enderman was right just a few folks at the beginning of the thread. Hell I don’t even know if they were aimed specifically at him.

    Lumintop BLF GTvn - Best Reflector Thrower?

    Re: Lumintop GTvn - Best Reflector Thrower? Gotcha my struggle was the overlapping of light. I tried calculating it based on how the light that is reflected off the reflector + spill calculated based on opening angle etc. I also tried using Lambert’s cosine law to find the cd or flux at every...

    Lumintop BLF GTvn - Best Reflector Thrower?

    Re: Lumintop GTvn - Best Reflector Thrower? I have always wanted to calculate such quantities before but how does one go about doing that? Especially the quantity of light that goes to spill and the quantity of light that goes to the spot.

    10,000 Lumen Thrunite TN36 Advice?

    Thank you! The Germans forums most certainly helped out with tons of reviews on it. Only issues are they claim the light is around 6000 lumens. I thought Thrunite follows ANSI/NEMA FL1 standards??? The TN42 did. Surely that couldn't be a coincidence. Because in my eyes saying a 6000 or even...

    10,000 Lumen Thrunite TN36 Advice?

    Hello! I have been looking to get myself a Thrunite TN36 (2017 updated model) in order to join the mega flooders club as my brightest flashlight as of now is the 4000 Lumen Nitecore TM26. 10,000 lumens sounds insane and will certainly light up my world a bit more. However, not sure if it...

    Tiniest Flashlight Ever Made!

    Hi my fellow flashlight enthusiasts! With millions of new flashlights coming out each day I've certainly lost track on "record holding" lights as they seem to change all the time. What is tiniest production flashlight out there right now? (Sure it can be whatever your definition of tiniest is...

    Powering My First LED.

    I've looked at that data sheet but it doesn't seem to show much else besides a rough chart. Is there no way to get any more specific of an answer? Also would voltage still be 2.95?

    Anyone know what light bar is used here in alien covenant??? Looks like a ridged industries Infrared Light bar at first judging by the real dark tint but the details don't match up neither does the illumination.

    Powering My First LED.

    Hi! Hope all are doing well. I am currently in the process of making a solar powered DIY light and for this application I have chosen a CREE XP-L HI LED. I have my LED's, my power sources, etc. However, I am struggling to determine how to power this light to my desired output. All I know...

    Acebeam X45 Flashlight Review (4x XHP70, 4x 18650, 16,500 lumens)

    I did not contact him regarding the X45 but about my Nitecore related issue. I was hoping he can mod my TM26 so it can catch up with lo you guys but he said he doesn't do those as they are hard to work with and the OLED screen breaks to easily. Fair enough.

    Acebeam X45 Flashlight Review (4x XHP70, 4x 18650, 16,500 lumens)

    Wait that doesn't make sense. The XHP70 has a max out put of 4022 lumens and the XHP70.2 puts out 4292 lumens. I can't see how a driver alone can squeeze out an additional 8000 lumens out of those poor LED's lol. What sorcery is this?!!
