I got my Lemansind 32 LED module today. I like it quite a bit.
At $40.05 shipped, I think it is a good buy, and makes a good general purpose, around-the-house, at-work, in-the-car, type of light.
Although the auction states that the seller is in Hong Kong, the adaptor shipped from California, and the shipping was fast.
--------------------------------------------------------------------------------------------
The fit & finish of the unit wasn't perfect, but it is good enough for it's purpose.
It has 32 Nichia 5mm LEDs mounted on a board, and underneath they are connected to their 22 ohm resistors on a circuitboard, and beneath that, another board ties the whole unit together with it's bulb base adaptor.
It is installed by removing the Mag's lens retaining collar, reflector, bulb and bulb retaining collar, and pushing the module into the bulb receptacle. The circuitboards fit snugly into the area inside the Mag's head, and it ends up being a tight, dependable installation.
Screw the lens retainer back on, and it's in.
I doubt that this installation keeps the light water resistant, as the reflector being gone leaves a gap in my light, between the lens & the lens retaining collar. The lens seems to pivot, in a springy manner, on the white bolt cover nipple in the center of the module.
The module is plenty bright for a replacement of an incandescent bulb in a 2 D Mag. I was surprised how bright it was, it exceeded my expectations.
The beam is a relatively tight spot, with ample spill light. When used in the house, the spill light illuminates the whole room, with the spot being about as bright as a one watt luxeon, although the spot is about twice the size of what a low dome & NX05 combination provides.
The beam is, as expected, tinted blue, as the 5mm LEDs are, and in the auction, it is stated that these are Nichia LEDs, although it wasn't stated what mcd rating they are.
I measured the current at 980mA to the module. This is 30mA to each LED. I would like to get into one of these and change the resistors to a lower value. I'd like to drive them at about 60-70mA.
My Streamlight 4AA LED drives it's 7 LEDs at 83 mA.
Outside tonight (near full moon), I was pleasently surprised at the amount of light it puts out, and how far it throws. I didn't expect 5mm LEDs to have any throw at all, just a nice flood for close range.
Treetops were illuminated, no problem (probably 40 feet), and I don't mean barely illuminated either. Houses across the street were lit well enough to read their addresses.
I have mine in a blue 2 D cell Maglite, with two of Chief_Wiggum's 4 AA-to-D cell adaptors, which are wired in series-parallel for 3V @ twice the AA capacity. So, I'm overdriving this adaptor a bit, with 8 NiMH in series-parallel. I can't wait to see the output on alkalines (especially those 1.7V Oxy-Alkalines).
*EDIT* (Actually, I'm not overdriving it. I just remembered that it can be used in a 3-4 cell light.) *EDIT*
Other possible configurations are:
2 D cell Mag w/ 3 C cells.
2 C cell Mag w/ 2 123 cells & dummy?
3 to 4 C cell Mag.
3 to 4 D cell Mag.
Single D cell Mag w/ 3-4 AA cells.
*EDIT* I checked it for fit in my 4 C cell Mag. It works fine, no problems with C cell Mags here. *EDIT*

The only negative I see so far is no candle mode. Since the adaptor loads through the head, the adaptor would be removed when the head is removed.
You could remove all this to use it in candle mode for extended periods of time, if you wanted to, though.
And of course, you can always just stand a D cell Mag on it's tail, although not very securely.
And finally, five out of five dentists surveyed recommended the Lemansind 32 LED module, for their patients who have a Mag they wish to convert.
