Here`s a light I haven`t seen before

[Badbeams3]

Jee, I`m sorry, thought I knew how to put a link here but guess I don`t. The light is on E-bay. Type in led flashlight, scroll down a bit look for "white led flashlight last for 100 hours" or something like that, selling for $19.95(dutch auction).They call it the LED TORCH. It looks a lot like a PLW or Lightwave but it is not. It has some circuit that allows it to flash. It has a weird lens to.

I'm going to buy one of these and see what the deal is. The claim of 9000mcd white LEDs is outlandish, but not totally, 100% unbelievable if they were measured on an integrating sphere while being severely overdriven. Yet the ad copy says the LEDs are "properly driven" to manufacturer's specs.

I noticed an epoxy "blob" IC on the circuit board, this is what would enable the blink function.

The auction doesn't end for another week, I paypal them the money, and get the light in another week.

See ya in about two weeks.

My guess on the 9000mcd is they are counting both LED's. I bet they are 2 4500mcd's Maybe??

Unless they're using non-Nichia LEDs, these numbers just won't come out in the wash.

Nichia LEDs are rated at 4800mcd (pre-1999), 5600mcd (today's most available) and 6000mcd (rank "S" that a few OEMs can get).

I'll have it figured out when I get the light. There are some rumours of both 6800mcd and 10000mcd white Nichias, but they're just that - rumours. Nichia denies their existence (they deny any improvements since June 2000) so I'd say it's about 50:50.
