I recently found a Romisen RC-C8 on ebay in the UK brand new, for about half the price it would cost from China - Bounus!
It arrived in 2 days, and the quality is very nice.
I have a question... I am currently running 3xAAA, and it doesn't appear particularly bright. The battery pack is sitting at 3.8v without load, and on high I am measuring approx 350mA at the tailcap. Now I am fairly new to this area, but if the Vf of the LED is not far off of that of the batteries, and the torch *claims* to have a regulated current of 800mA, should my measurements be closer to this value?
Just thinking out loud really. Might mod this light anyhow, as I really like the feel of it but not too keen on the beam pattern.
Sorry, should have mentioned. It's running from 3 x AAA GP Recyko LSD NiMHs.
I'm not too concerned about the brightness, it's just that having measured the current, I wanted to understand the relationship between the voltage and current at the battery and at the driver.
