The dropin is packaged in a resealable plastic bag.
The dropin is quite unique.
It comes with an all brass construction and a triple TIR optic.
The manufacturer allows the user to individually select the installed XP-E emitters (White / Neutral White / Warm White / Red / Green / Blue / Amber / Royal Blue).
Overall, the dropin is nicely machined with no visual artifacts.
As with all P60 dropins, there is a dual spring design in order to ensure good +/- contact.
The driver contains 3 transistors - one for each individual channel.
The driver is held in place by a retaining ring.
There is also a retaining ring in the front of the dropin.
By removing it, the user has access to the triple TIR lens and the triple XP-E board.
Notice that my color choices were: Royal Blue, Green, Red
User Interface
The dropin has a basic UI with mode memory.
A tap initiates a mode change which follows this pattern:
LED1 (High) > LED1 (Low) > LED2 (High) > LED2 (Low) > LED3 (High) > LED3 (Low)
The cutoff voltage is set at 2.7V, while the emitters start blinking from 2.9V and downwards.
Unfortunately, the driver can't run on all three channels simultaneously, so only one emitter can be lit up.
Performance
I used my RDTech DPS5020 PSU to precisely measure the current draw of each mode.
Here's my results.
Royal Blue (High): 1.21A
Royal Blue (Low): 0.02A
Green (High): 1.26A
Green (Low): 0.02A
Red (High): 1.20A
Red (Low): 0.04A
The manufacturer's details indicate that the driver is Constant Current.
Unfortunately, my tests can't confirm the claims, at least with an 1S input.
Here's the Royal Blue emitter tested - though all of the emitters should follow the same curve :
What's left to do is check the performance under 8.4V and see if CC is indeed existent at this voltage.
My tests should arrive shortly.
Wall Beamshots
Thanks to the TIR lens, the dropin creates a uniform beam with a discrete hotspot.
Royal Blue (High)
Green (High)
Red (High)
Overall the dropin is very good.
Its build quality ensures good thermal management and the user selectable XP-Es is what's making it stand out.
Though, I would like to see a driver that could pull a CC on an 1S input.
Ummm, with an I-V curve like that (looks like simple resistance, not regulated in any way whatsoever), I don’t quite think I’d trust the specs which claim
3V - 9V ( 1 or 2 x 18650 / 3 x CR123 )
unless you want the poor XP-Es to go poof.
And “thermal management”?!? Mmmmmm, I don’t think so…
I was initially thinking, “Ooh, a WW triple in a drop in! Woohoo!!”, but nope.
Thanks for the review bilakos10! Do you know if it's possible to get the driver only (without buying the whole dropin) from Kaidomain? I tried to ask Ban from Kaidomain but didn't get any answer so far.
Thanks bilakos10!
I see that the mcpcb is a standard KD. How they solved the problem with a thin MCPCB and a long legs in the optics. The picture doesn’t show this too well. More photos are welcome.
I don’t know about TIR hole size in this p60 but is it possible to use other white led with more efficiency? Would be nice if it can use white xp-l hi or xp-g3 or whaterver combine with color xp-e2.
Finally -
Awesome
I’m a railway employee so with these I can use my P60 lights as signaling lights.
What’s the output like?
is the low mode more of a medium??
They should fit just fine in solarforce lights wouldn’t they??
Thanks
There is a driver for the XM-L Color led on KD, also available in MtnElectronics (the led is out of stock at ME). I have no idea if a triple led PCB could be adapted to run with that driver.
The one I’ve used more often — about an hour total — now has one dead LED.
I’ve emailed KD about returning/replacing it.
The other 2 LEDs light up normally.
I don’t know what “CDM-2500 circuit inside” means.
Won’t try taking it apart to find the problem until I know whether KD will replace it.
Any thoughts welcome, about what might have gone wrong.
