    Moddoolar Triple Wasp Cooling Head and Glow System

    I’m confused. Isn’t it the case that the calculation of watts, volts, and amps is based on the power supplied to the system, not the specific voltage across each emitter? We are calculating the power coming from the battery so we would use the nominal voltage of the battery which is 3.7 volts...

    Lumens per watt

    Thank you so much for the reply. I feel like I might be getting it now. So the data sheet table I first came to for 4000k s3 shows at 350mA and 85C “156” is the minimum lumens. The forward voltage at 350mA and 85c is 2.73V. So 2.73 * .350 is .9555 watt. So basically a watt. so for that specific...

    Lumens per watt

    Any help is appreciated; does anyone know how to look at a Cree spec sheet and determine lumens per watt? Specifically the xd16 s3?

    I’m trying to find the lumens per watt for Cree xd16 70 cri emitters and have no clue how to figure it out from the Cree spec sheet. Can you help?

    219c triple max lumens output

    Can anyone help? I have a 219c hi CRI 4200k triple emitter on a Minion flashlight with the 371d version 2 lux-RC engine. It looks like the highest mode uses 17 watts. I am using a Keeppower 1200mAh 18350. What would be the max lumens and the formula to figure that out?

    Just seeing this. RIP

    219b vs 219c

    Hey, thanks again. I hear the word efficiency and I never knew what that really translated to. I thought less efficient usually meant a higher forward voltage and thus used more current but I wasn’t sure what that changed for runtimes or brightness. I appreciate you explaining that.

    219b vs 219c

    Thanks. So same brightness but less runtimes?

    219b vs 219c

    In a current regulated light, such as the Aeon Mk III S2, that has a 219c emitter, what would happen if I swapped it out for a 219b? Would it be dimmer but keep the same runtimes? How much dimmer? 20%? Would high mode (160 lumens) be the only mode affected? I realize the algorithmically way our...

    mini ml-x emitter swap wanted

    Is there anybody out there willing to switch my brass Mini Ml-X foursevens emitter for a 4000k 219b? Vinh switched it to a XML2 U2 5000K a while back. It is one of my favorite lights but I never carry it anymore due to the tint. Phillip
