Sold/Expired ALL SOLD - Custom Aleph and McGizmo Light Engines

All sold. Thanks CPF!

For sale are some custom light engines for use in Aleph and McGizmo lights that use the screw in light engines.




These 3-level Aleph light engines are built with a custom designed circuit board using four AMC7135 IC's at 380mA each. The aluminum can was custom machined for the direct thermal path (DTP) copper MCPCB, and dissipates heat quickly into the head of the light. These are ideal for use with a single 3.7V Li-Ion cell (2.8 - 5.5V). Each light engine is fitted with a brass battery contact for long wear.

Re: Custom Aleph and McGizmo Light Engines

I'll take #4.

Custom Aleph and McGizmo Light Engines

DatiLED anymore 5000k's available anytime soon? Was just pointed in your direction, yesterday, for a Alph compatible LE [emoji6]

BTW backup to #4 if it falls through.

Re: Custom Aleph and McGizmo Light Engines

I have some 5000K XP-L LEDs on order, and will install them in a few light engines this coming week (pending my day job workload). The LED order ships on Monday.

Excellent! Was wanting to get a Mule from the Shoppe just kind of...Because, and was asking around for a really cool LE. Looks like I found one..eventually.

Count me in for a XPL HI 5000k whenever you have time.

Thank you!

Re: Custom Aleph and McGizmo Light Engines

Derek, I'll take 3) if you're prepared to shim the emitter an extra 1mm.

Please see my PM.

Re: Custom Aleph and McGizmo Light Engines

Dumb question, but I haven't taken apart my Haiku, will these fit?

If they will work in my Haiku, I would like one of the Nichia's, actually I would do either, even one of the 5K's would be nice.
Thanks for the help.

I responded to your PM in detail, but will explain the difference here for the benefit of others. I can't raise the LED on this new version of light engine, as it uses the direct thermal path MCPCB. It is slightly higher than the previous version, but not a full 1mm. The method that we used previously, used an 8mm MCPCB sitting upward into the reflector by 1mm. The work-around is to remove 1mm from the back of your reflectors to be compatible with modern LEDs. I have successfully done this with a lot of the Luxeon McGizmo PDs, HD45s, etc. It sets the LED die height the same as the original Luxeon, in the focal point of the reflector.

These are a direct fit in the Haiku. Simply remove one light engine, and screw in the other. Make sure that you are using a 3.7V RCR cell for full power.

Re: Custom Aleph and McGizmo Light Engines

Awesome. Thanks for the quick reply. I just wanted to be sure. I will take a Nichia. Thank you.

I will take #5 please. Pp incoming!
Or 6, if Str8 is 5 : )

Derek - Silly rookie question. What's the benefit of direct thermal path? Doesn't it dramatically increase lumen or something to that effect?

The direct thermal path (DTP) wicks the heat from the LED dramatically faster than the standard MCPCB with the thin substrate separating the LED from the metal base (typically aluminum). The DTP copper MCPCB quickly spreads the heat into itself, and the surrounding metal. In the case of my light engines, an aluminum or copper can. This then enables the heat to be transferred into the head and body of the light. Excess heat will cause a decrease in brightness of the LED. Over time, excess heat will kill an LED.

Re: Custom Aleph and McGizmo Light Engines

How well do the XPL HI LE's work in Haiku's? There is no dome on them (I think). Just wondering what the focus is like.

Thank you sir. So just to make sure that I understand, building DTP into the process is a long term performance benefit. Both aiding the brightness while extending the life of the LED?

With a beam angle of 115 degrees, it is the same as the XP-G2. It should perform fine. In my experience, it makes a slight ring in the beam. However, I have not tested the XP-L HI in a Haiku.

At 1.52A, it is likely overkill. However, anything that can keep the LED cooler will result in sustained brightness, and longer LED life.
