Heart of the Mule (Dial-Up Beware!)

[Dutch]

There's a lot to look at in that little Fella!

Sorry about the dust specs! I ran out of canned air...

Mule porn!:devil: What? It was made in 2005? :huh::nana:

Some of the Masters BEST work by his own admission.

BTW this is just about the nicest Light engine I own for use with the Mule.
I tried a bunch from Seoul Cree and Lux III as well as Lux V based Light engines.
This one made by Don ( Don't ask. Don isn't selling them) uses a Cree emitter. I don't remember the specs, They don't matter. What does matter is that I get a very nice Mule beam with good color and really good run time. I have found that most of my Light engines were designed for lights with reflectors that were designed to be very bright with little regard for runtime. As a result IMHO a CREE based Light engine driven at 500mAh or more are really too bright for my purposes. This emitter is being driven at a "more reasonable"(IMHO) level will emit it's wonderful light for a somewhat longer time than the harder driven Cree based light engines.
The next gen multi level Light engines from the shoppe are seemingly impossible to get (they are always sold out when I go there to order one). So in the mean time This will be my Light engine of choice for the Mule.
Thanks again Don.
Sorry to ramble on but once I start I like to complete typing concept for you to read.

True Mule porn.
Sorry the image isn't bigger Oh and some of you have actually seen it before...

Yaesumfo,

I think I need to set the record straight here a bit. When I said that was some of my best work, the comment was in reference to the appearance of the solder job and my tongue was firmly in cheek. That is a Nichia 083 LED that was solder flow mounted to one of Wayne's super thin PCB's which is loaded with vias for excellent thermal relief. I soldered the lead wires to the PCB after it had been epoxied to the E-screw and the thermal path was so good that I was unable to get a good solder flow at the lead pads with the soldering tip I was using. I didn't have enough heat at the tip to over come the rapid dissipation into the E-screw. I also used an excess of Arctic silver epoxy in bonding the PCB to the E-screw and just pressed the PCB down letting the excess come up through some of the vias as well as around the perimeter of the board. This LE was made for bench testing the LED and use in evaluating the LED in a portable manner with the interest being in fixed lighting applications.

That LE is about as butt ugly as you can get but it does what it was intended to do quite well and the thermal relief is there. You asked me if I had a LE that would work in the mule and you said you didn't care what it looked like nor if it was a stellar performer. You didn't tell me it would be a Poster Child that would get public exposure! :nana:

Don you never told me not to post a picture!!:shrug:
Sorry. I will hide these images forever never to be posted again.
Hey what can I say. It may not be pretty but it does a BEAUTIFUL job. Perfect...
Sorry. Won't happen again...

Yaesumfo,
No I didn't tell you not to post a pic and I wouldn't. It's yours to do with what you wish. No harm and no foul. The first time you posted this pic and said not to blame you for the crappy soldering job, I realized that some things just shouldn't leave my bench anymore than I should saunter down the street in my B-Day suit. :green:

LOL, certainly a joke about the solder job on that Nichia based LE. Don's soldering is much much much neater in all other pics I've seen.
