I have a Jade Master bought from KD with warm tint and an XR-E led. It realy has a pleasing warm colour and much brighter than I thought a warm tinted XR-E would be. These definitely aren't warm P4s everyone calling just too dim. Or are they? Solarforce has a warm drop-in even with a lower price than this but it could be something with a lower bin too.
Too bad I bought the KD Q35A drop-in some weeks ago, it doesn't have proper mode memory. But I wasn't that impressed of warm white anyway, atleast that one was very yellow/brown, neutral would probably be nicer.
OK, you're right about this. I should have used the power output/input efficiency. But we still can't know the output current because of the buck circuitry. It may be loosing its %30 power in the coils and not giving any more than %80 of the input current afterall.
A totally ideal buck driver should give 1.42Amps on the led for 4.2V input, on the other hand :)
I hardly notice PWM and surely did not on this one. Can't tell anymore since i swapped the driver to an Ak-47 which i modified to 700mA (killed a 7135amc chip) and brdiged to 2 mode low and hi. Less bright but still nice. Probably just playing it safe but i had a feeling it would survive at 1A but then i gain i have nothing to back that up scientifically. I wish more emitters were available in warm white and neutral.
Retail price for CR123's in the UK is about £8 each so about $13... you could by a new XM-L flashlight every hour instread if you were foolish enough to pay those prices :P
Of course anyone with any sence just orders them online...still it works out much better to use rechargables.
Aren't supposedly all the budget drivers crammed with the linear regulatorc AMC7139 tolerant for up to 6V? I've read that somewhere for the AK-47 at least... Heavily unconfirmed!
