We have just finished testing the first prototype of the Search and Rescue series of lights, the SR450A.

This light uses the Cree XPG-R5 LED mated with a 58 mm reflector. Bob at RMSK has a picture of the
unit up on his web site. It can use any of the NP or FR battery compartments and will work with
any battery supply from 3 volts to 14 volts. 4.5 volts is required for maximum output. The LED is driven
at 1.5 Amps and is current limited and fully adjustable from maximum to zero output.

With a 2 x 18650 battery compartment the light is 10.5 inches long. Shorter battery compartments are
available. Maximum head diameter is 2.65 inches and 3.5 inches long.

This light uses a Phoenix 58 mm reflector that has a power input to output ratio of one to 382. At 1.5 Amps
of drive the XPG-R5 LED in a bare bulb condition has an output of 108 Candela at 12 inches. That gives the
light a 41,000 Candela output. The output in Lux bare bulb at one meter, (39.4 inches), is 97.5 for an
output of 37,200 Lux.

We will start production in a week and hope to have them at RMSK by the end of the month of June, first week
in July at the latest, depending on anodizing time requirements that I have no control over.

WOW just when i am about to buy one of your smaller lights you come out with another big one.:D

nice...so the production model will be entirely black HA when finished with the exception of the silver potinometer dial - correct?
Nice to see it should fit the first generation NP and FR body tubes.

I know, just love my FR400A and this is like it with a much bigger head.
 
We just put in the mail to RMSK a shipment of the SR450 lights.

At 8 an foot distance the hot spot is 5 inches with an 18 inch spill.
At 40 feet the hot spot is 16 inches and the spill is 60 inches.

sounds like a freegen laser!

It will run just fine off of a single 18650 right?

I saw and spoke with Curt about this yesterday. He informed me that it can be used with any of Peak's existing LEO series (18XXX) battery compartments, using any of the battery combinations the tubes will support. This means it can run off of:

1 X 18650
2 X 18650
1 X 18500
2 X (R)CR123
3 X (R)CR123
2 X 14500
3 X 14500
2 X AA
3 X AA
4 X AA
and probably a few more I've forgotten.

However, as I understand it, this light does require at least 3.0v to operate, and at least 4.5v for maximum output. Even at a far less than max power level it throws dramatically better than my NP300 with an XPG.

One little side note: it has an infinitely adjustable output which really will let the anti-light, black hole CPF'ers out there dial it down to a BARELY perceptible, stick the light into your eyeball glow. I wouldn't want to be the generous, scholarly, sleepless machine-type person doing a nuclear winter runtime test on this sucker with two 18650's.
 
No Rage I talking to a lady that was having trouble with a light and needed to get it out
today for her fathers birthday. Yes the SR450's that I got all had the 2 X 18650 body, really with the large and deep head they are more balanced than with a smaller body...but they will
work also. It's 10.5 inches long 2.7 inch head and weighs with 2 18650's 1 lb on the money.
Can't wait till tonight to check it outside for throw

A few more pictures of the flashlights would be nice for the website. Especially ones showing the business end. If it weren't for CPFers showing me pictures I would not have known what I was ordering when I got an FR400 and that is kind of a turn off.
