Yeah, you mean the thermal path is just as lousy as a P60 light, because the 348 uses the same construction to hold the pill in placeā¦
I guess they do it for easy production because it will always fit like this.
Sounds a little high to me, but probably itās normal.
1.5 Volts x 1.5 Amperes = 2.25 Watts x 75% efficiency of driver (guesstimated) = 1.7 Watts to the LED = approximately 170 Lumen x 60% efficiency of the reflector and lens = 100 Lumen light output.
Hmmā¦ thatās twice the measured output of 48 Lumen.
I donāt knowā¦
Maybe that was 48 Lumens on 1.2 Volts from a NiMH.
(letās say 1.2 Volts x 1.2 Amperes = 1.44 Watts x 75% eff. driver = 1.1 Watts to LED = appr. 110 Lumen x 60% eff. optics = 66 Lumen ā¦??)
Itās a nice host thatās proven fairly reliable. My biggest long term concern has been the switch but they seem to hold up pretty well. Given that they have made a classy, reliable host that is mod friendly, Iād certainly order some more. Itās not perfect but for what it does already it ticks a lot of boxes. A must have for modding or off the shelf edc. The upgrades in quality needed to make it superb would take it out of the budget realm.
Since this is for pops I think Iāll change it to a tiny10 - 7135 with two chips instead. Should be 86mA, 250mA, 860mA which is more reasonable. He tends to yelp a lot.
