off current is 3µA -> almost nothing. I am going to try measuring the current. The problem is the voltage drop over my multimeter. But maybe my lumen measurements do help:
Moon: 3/ 2.5
Low: 100/75
Med: 350/ 290
High: 800/ 650
Turbo 1800/ 1400(turn on) -> 1280 (30s)
But these values could be off, I have to calibrate my sphere better
Thanks, it looks like something like 5A on turbo, maybe 1.5A on high and 600mA on medium. You need two thick and short wires connected to multimeter instead of the default thin probes for true current values.
Maybe this dropin isn’t so bad as it is press fitted and the light get hot when used.
ATR now works as stepdown in turbo mode.
I ordered wurkkos w03 to try. Just for fun, I like the UI.
The SC18 uses a 1 minute turbo timer + ATR at 43°C if you continuously reactivate turbo.
What’s the ambient temp for the test? I reviewed this and at 20°C it maxed out at 54°C at the head and 50°C on the body. This is perfectly fine, but for places that are warmer it could become an issue if one isn’t smart enough to manually reduce the level or hey sit it down somewhere. Although in use, would it actually heat up as hot as you saw, not likely since the air is moving around it and your hand conducts heat better than air sitting on your desk.
Your lumen measurements in comment #3 are very close to mine, some are exactly the same. My tube is calibrated with maukka lights, so you may not need to change anything.
Is it possible to remove the head? Is the body tube attached to the head by a threaded or press-fit connection?
I would like to modify the driver to have button standby light.
This has deterred me from buying so far, as well as the fact that the button seems to protrude too much. It is problematic to all the time lock out the button.
In the meantime I realized that the body and head are probably one piece and the shelf is holding the driver down.
It’s incorrigible, uncustomizable.
It happend that I didn’t get a notification about new replies, sorry. I received a new unit and can confirm, that it regulates the temperature to around 45˚C, although the pcb has the same date marked (22.05.17). Good to now, that my numbers seem accurate.
