From the Cree newsletter:
First up is the XLamp XP-P LED, a breakthrough XP package designed for Extreme High Intensity application. A 1 mm2 die/light emitting surface can accept up to 3A of current and deliver up to a blistering 700 lm/mm2. If you are in the business of creating the narrow beam, long-throw lighting applications we have an unparalleled part for you!

Were you able to measure how throwy the dedomed XPG-2 was?
My throwiest light is the Nitecore P30, i wonder how much the dedomed XPG-2 chip or this new chip would blow it away.
The P30 uses a XP-L hi, this gives more light but is not as throwy as the dedomed XP-G2, or the more modern domeless leds. But frankly, nothing revolutionary has happened the last couple of years with leds, I think that a flashlight the size of a P30 can be made twice as throwy with a new led and suitable driver, you will notice that, but does that blow you away?
I don’t do my own modding so if this chip is amazing i would buy a new light that uses it.
My light is rated for 618 meters of throw, though i don’t know how much that is in real life, i have used it to light things up several blocks away but i live in the city and don’t have the opportunity to test 600-700 meter away structures without blinding other people.
One of my favorite toys was (just came across it last week, in fact) a ~4500K XP-E in a crappy C8 host. Teeny chip in a relatively huge reflector threw an assload, even though I didn’t hit it that hard (only 1.0A or 1.4A, forgot which driver it has).
Dedome that beastie and hit it a little harder, and it’d keep up with a lot of more modern throwers.
Bigger chip, lots more current, bigger brighter hotspot, is kinda cheating.
My first modern LED flashlight is a Dorcy XP-E light, i still have it, probably still works. Still has its dome and its driver circuitry is a single resistor.
I should test it against my Nitecore P30 if i ever get a suitable test location.
Hmm,
I might have that covered too, i can use an industrial building and my old Garmin GPS to map out distance.
If i do test all this i’ll post the results.
Yeah,same for me with C8’s and super smooth polished plastic reflectors.
I was surprised how much the old XP-E throw well considering these low current, even more after changed the junk driver with 4xAMC and switch with omten 1288 pcb.
A good gift for friends.But I’ll never buy them again
