As usual, lightmeter reading are EV's (Exposure Values) with a reading of 8 being what I consider minimum useful illumination level, 12" from torch.

Horizontal X axis in 15 minute grads.

Ultrafire CREE dropin unit

The graph above shows the RT's I achieved with each setup.

The CREE dropin has a stated range of 3.6v-9v.

So, using RCR123 3.6v 800mah cells, I did some testing.

First Xenon, 2 cells. Then CREE 2 cells, then CREE 1 cell.

And yes, the dropin appears to be extremely well regulated, it gives a narrower spot than the stock Xenon bulb assembly, is much whiter, the Xenon is yellow/amber, as usual.

RT's, and output is pretty much as expected.

The Xenon gave a brighter output, 2 EV stops, for a shorter time

Xenon, EV16 for 30 mins, CREE EV14 for 120 mins, CREE EV14 for 90 mins using 1 RCR123 3.6v, again very well regulated.

Initial battery current using CREE dropin, 2 x RCR123 3.6v is 360ma, using just one RCR123 3.6v, 600ma. Pretty much as expected for electronics.

In comparison, the Vinet, single RCR123 3.6v, is shown.

Benno, Xenon and CREE dropin all thoroughly recommended.

As are Dealextreme, excellent service.

If it's not too complicated to understand, here is a comparison between standard and CREE'd

Elly & Benno 501B.

Thanks for the runtimes.

How does the flood from the drop-in compare to the Xenon bulb?

The flood is bright and pretty even, over a wide area with the Xenon.

The central spot on the CREE'd version is quite tight, there is flood, (spill) but at a lower level than off Xenon.

I'd say it's comparable with most other high output LED torches, bright centre spot, reasonable flood.

A nice bright, well defined spot & flood combination.

No beam shots, I'll leave that to others.
