So I was swapping some Malkoff modules around and was checking my M61W. It's one of my favorite in the house lights.So I'm pretty sure I have done a current draw on this before but not sure. Well the dam thing is pulling 1A at 6 volts. 1.2 with a 18650! I know the warm series is battery hunger but that doesn't seem right. My gauge is ok as it reads my M61LLL the same as I have always gotten on it. My other M61's are where there supposed to be. 650-800. The M61W should be drawing 650 or so off of 2X123's. Can anyone verify what they are getting with there's. Anyone ever hear of a dropin increasing in draw for some reason. Strange 樂
Unfortunately I sold mine (previous gen to current) I must have been in a hurry and missed it.
More details...actual voltage of cells, was the module fresh off the shelf or already being used. It shouldn't be that far off. I notice once a light warms up, the readings can be different. Are the cells fresh? It only takes a second for the readings to drastically change when using cells. using primaries with 6.xx volts only takes a few seconds to be below 6 volts; resulting in skewed results. This is a reason why power supplies should be used for current draw readings. I don't have a good answer for you. Seems that the voltages are not what you think they are.
I am wondering if the info on the site is accurate? It shows both M61/M61N 800ma@6v but M61W@650ma. I would think the W is less efficient but I could be wrong. I know with the M61/M61N it doesn't take much to go from lower draw to an amp or better. This is where I can see the big increase you are seeing, but i don't know all the details. They do still seem a little high, but you have current gen where mine are before the driver update; so your readings sound in line for other voltages. If you are thinking you are reading 6v but aren't; thats where it makes sense to me. Anyway...
