KD's Q5 Maglite Drop In

I just received the KD's Q5 Maglite Drop In.

From ordering to shipping it took 7 days to Socal.

Costs $29.00.

Comes with no instructions.

Cree Q5.

2.0V to 4.5V Boost-Buck Current.

Fits Maglite 2 or 3 D sized lights.

Beam is ringy. Very slight yellow color. I like the Malkoff 2-3 D Drop In better. The Malkoff has a smoother beam and is brighter. The 3 Malkoffs I have whiter beams.

I would pay the extra money and purchase a Malkoff Maglite Drop In due to the brighter, smoother and whiter beam.

No Thermal Paste! The Q5 sits on an aluminum cyndrical shaped pedestal.



There are 2 separate pieces. The center screws out.







The Q5 Drop In fits tight. The "tightness" of the fitting holds the drop in.





The base of the reflector needs to be cut off.



After screwing the lens bezel assembly the drop in needs to sit this high in the reflector.

These are the lux readings I got. I am using a Meterman LM631 Light Meter measured at 1 meter. I waited 2 minutes before taking the readings. Both lights had fully charged. batteries. Radio Shack Rechargeable Nimh 4500mAh Batteries.


KD's Q5 Maglite Drop In 3D Maglite - 8860 lux @ 1 meter

Maglite 2D Malkolf Drop-In - 10,000 lux @ 1 meter

Maglite 3D Malkolf Drop-In - 12,580 lux @ 1 meter

Maglite 2C Malkoff Drop In - 8980 lux @ 1 meter

My Maglite 2C Malkoff Drop In has a higher lux reading than the KD's Q5 Maglite Drop In 3D Maglite.

The Cree vs. the Malkoff SSC will obviously look ringy. Maybe try a textured reflector, or stipple your own reflector. That may help the Cree, but it may not be worth it if the output is already less than the Malkoff.

You could try using it in an aspheric mag set up with no reflector.

Great pics, as always, Ernie. Thank you. To me, there's no doubt that Gene makes a premium, hand-turned product. I'd like to know how the KD compares to the Terralux and or Magled; those are the real competition to me, not the Malkoff.

ernsanada,
I'd be willing to send you a Malkoff stippled reflector if you need one...

A simple thanks for your great reviews!

I wouldn't mind seeing that. I hear the cree's do pretty well with aspheric lenses.

I didn't realize that the reflector is unused in a aspheric setup. Learn something never everyday.

Great review as usual erns! :thumbsup: Well from my experience with using Crees in a stock Mag reflector, I am not surprised with your results. I am quite sure KD's Mag dropin was only intended to be used with their aspherical lens as Crees seem to perform better than Seouls setup. Anyone who purchases this dropin to use with the stock reflector will most likely be disappointed. I bought two of these in a complete kit (Aspheric Lens, Bezel and Dropin) and am still awaiting to receive them.

Would it be a problem to show a beamshot from a stock Mag 3D or Mag LED 3D. Thanks

yeah i think the cree is better suited for an aspheric lens.

what's the current pull for this dropin?

The current draw is .72A using the Radio Shack 1.2V 4500mAh Nimh Rechargeable's Batteries.

I expect a ringy beam from the Cree. I think these were designed primarily for use with Kai's vaporware aspheric lens. I was disappointed to find that it was only driving the cree @ ~700 mA. But then again if it is as poorly heatsinked as some people suspect than perhaps that is as high as one should push it.
Thanks for the beamshots!

Thanks for the review. I was seriously considering getting this, but not anymore.

Dear Ernsanada:

Great review you have there. Do you mind to post up a runtime chart on malkoffdevice SSC drop-in? I doubt the higher output can remain constant overtime. With boost & buck current regulated circuit, 800mA is the max of what I can do.

With current regulated IC boost and buck IC, there is maximum current you can supplied to the LED. The accurate current is more likely to be 750-800mA. The LED is heatsinked probably, you just can't see the thermal paste under the LED.

How many 1.2V is used there? The IC is supposed to be used with 2V-4.5V of Vin supply.
