XB-D and XT-E drop-ins

LED Flashlights – General Info
1

These LEDs seem to have fallen out of the spotlight... so I thought I might ask around about them before I dedicated $$$ to making p60 drop-ins with them (I have 2 L2's inbound which need filling ;) ).

I am planning on making P60 host with the following:

XT-E White

XT-E Royal Blue

XB-D White

All drive at 1A, 20mm boards (cut down to ~17mm) all off Cutter

I will be using TIR optics aimed at maximum throw if possible.

The Questions:

Has this been done before? I have search around but have not found. If someone has done so I would love to know if the exercise is pointless before proceeding with any purchases.

Is there a good cheap source of P60 pills (minus reflectors) sub $2 each (I currently only have 1 empty pill and want to keep the price of the build to a minimum).

While I am putting an order in at Cutter is there anything cheap I should include? :~

This for the pills. It is $3.5 + ~$1 shipping for 5 pcs.

But you'll need springs too, here.

Maybe it can come cheaper if you bought from Kaidomain or DX in bulk rates.

But why, XT-E or XB-D? They don't offer any farther throw than XP-Es, AFAIK.

Because someone needs to test them! I’d put yhem in a normal p60 host with a regular lens and compare them to the curreny leds we have. Shoot try them at 1.5a. Who knows.

That is the way things work, testing!!

Good to know someone will tell us how good those leds work on small reflectors.

Then I shall be testing my high lumen Nichia's in P60s. I know what testing means. I have an Osram p60 at home that I love to use time to time. For the new Cree's, Maybe they are indeed shooters with their small cores. They look like good value emitters already.

Curious... which one of these is the XT-E? Its the second one right? Kind of reminds me of a luxeon rebel.

Haha tricky question, it is the first one with the piramid shapped lens inside.

Kokopelli, don't take me wrong haha, I meant it is good to see tests of new leds in general as we don't know 100% how they will perform.

By the way the Osram oslon SSL80 is not a bad led at all, good for throwers, almost as good as xr-e by eye.

Is that a remote phosphor thing?

Awesome... thanks Kokopelli

Exactly what I was looking for. (be nice if they are copper)

I need to move a few items along before I do this so it may take a few weeks... but in the mean time I will order those pills. ;)

Both of those are XT-E Components, the first is the XT-E White and the second is the XT-E High Voltage. [quote=kramer5150]

did you ever get those xb-d and xt-e drop-ins built up?

The die is so small, it seems they would throw farther than the xp-e2 at equivalent current. High run currents do not usually make sense in real world, anyway. For toys, yes. Not tools. (Esp. above 700 ma in any battery form factor.)

I am guessing, tint issues like the xt-e had, killed the xb-d. ?
