DIY Reflector Shields for Magicshine/Clones (& Flashlights!)

andychrist · Jan 7, 2020

Kaidomain gifted me this Magicshine MJ-808 Clone with a very blueish tint and pronounced hot spot. Here's how I modded it Kindergarten style with just some aluminum foil, adhesive backed holographic orange mylar and a double layer of packing tape.

Knocks down color temperature without lowering lumens. Smooths beam without sacrificing throw. Cost next to nothing so win-win-win!!!

Okay I really have no use for this lamp as a headlight, will revert to its status as a tail.

Plain Reflector Shields for Lamps at 4000K

XHP70.2 4000K bike lights don't seem to need any color modification but with their aluminum reflectors their beams are not quite as smooth as those from TIR lenses. Bezels on most not compatible with the 39mm Action-LED Wide Angle Lens, so the only current fix seems to be the application of some kind of diffusing film. Trouble with this solution is that scattering light kills throw. Installing external reflector seems to restore it at least somewhat.

Of course these reflector shields are just prototypes; if I ever have the time and inclination to devise a more finished version will substitute either flashing or stainless sheet metal for the aluminum foil and secure over EPDM tape with M5 SS flange head Allen screws and nylock hex caps, P-clamp style. For the two JKK03 flashlights I have on order might be able to install those Action-LED lenses instead of diffuser film, they're less lossy to start out with.

New Improved Reversible Reflector Shields for CW or NW/WW!!!

These new ones came out a lot better than the first prototypes. Was able to extend their length by 3/8" for more effective cutoff.

Now each is reversible so can be used either to neutralize cool bluish lights or simply to improve the beam from neutral or warm lights that don't need any color correction.

Versions pictured below are 37.5mm Diameter, fit Sofirn SD05 & SP33.

Currently working on similar new design for 46mm JKK05 & 56mm JKK36R/KDLITKER BL70S.

Will attach to bezels with narrow strip of heat conducting aluminum tape so will double as cooling fin extensions.

Reflector Shield for KDLITKER BL70S & JKK36[R]

The KD BL70S and JKK36 share basically the same head, their bezels are 56mm in diameter.

Replaced my home-brewed diffuser with a layer of d-c-fix self adhesive Milky Privacy Film, much clearer and sparkly.

Also, this is how the shields [for the Sofrins SP33 and SD05] are shipping, with protective wax paper over the aluminum tape's bonding side that seals the unit to the flashlight bezel. Just trim ends as may be necessary, peel and stick!

New reflector shields and lenses for Sofirn and jin heng flashlights

So picked up these 38mm and 50mm diffusing lenses on Ali, in the hope that they'd somehow fit my JKK03 and JKK36R flashlights.

https://www.aliexpress.com/item/32869352038.html
https://www.aliexpress.com/item/4000203010459.html

Also got a couple 32.5mm 5-DEGREE PMMA OPTICAL LENS FOR CREE XHP70 from KD to see if they'd work in my Sofirn SP33 V3.0 flashlights.

Turned out that though the lenses from Ali were too narrow in diameter to be held in by the bezels on the jin heng flashlights, they did fit perfectly inside them. 50mm lens actually locked onto the silicone O-ring that was under the original cover lens of the JKK36R and won't even come out now.

38mm lens clicks in place on top of the JKK03 cover lens and seems to stay put there as well. Can't believe my good fortune with these!

Though in all honesty, have to admit that the d-c-fix self-adhesive Milky/Sand film affixed to jin heng' s original mineral glass cover lenses improves the XHP beams more than do these plastic diffusing lenses alone. However where I was able to combine the two on the smaller JKK03 (by dropping the Plano Convex lens onto the cover lens already modded with d-c-fix on its underside) the result was better than either single method. No hint of corona/halo/tint shift, just a subtle hot spot within an even, well defined flood. Again, home brewed Epileptical ™ reflectors help contain top of beam to redirect light that would otherwise be wasted above the horizon, downward onto the path.

Now for the most amazing discovery so far: Kaidomain's 32.5MM (D) X 18MMM (H) 5-DEGREE PMMA OPTICAL LENS FOR CREE XHP70 turned out to be a DROP IN REPLACEMENT for the original aluminum OP reflector in Sofirn's SP33 - Thanks for sharing that link, arc!!! :thumbsup: Combined with the original glass cover lens already modded with d-c-fix, produces a super sweet beam - its soft spot further enhanced of course with another of my Epileptical ™ reflectors.

All above pics were taken with the Sofrins on Low, otherwise their fields of illumination would have been too large to capture. Anyway my iPad sets the exposure automatically and I didn't edit in any adjustments, so the pics are not necessarily accurate as to how bright the spots appeared in comparison to each other - just trying to record the individual beam patterns of the various combos, as per requests.

Garry, shots from the JKK03 and JKK36R with and without d-c-fix/Ali lenses up next.

Just taking some time because my [top of the line] 12.9" iPad Pro sucks donkey balls.

andychrist · Jan 23, 2020

Once again, all pics below taken with the jin heng flashlights set to Low because my iPad couldn't take in any broader/brighter beams. Auto exposure.

Couldn't get a shot from the JKK36R 4000K with only its [SMO] reflector because the 50mm diverging Astigmatic PMMA Lens got wedged in so tight, can't get it out now. Guess that's a good thing?

garrybunk · Jan 23, 2020

Thanks Andy! So that 32.5MM 5-DEGREE PMMA OPTICAL LENS and the beaded lens do a pretty decent job spreading out the beam, with adding DC Fix adding even more smoothing. I wonder how much output is lost, especially with the combination of lens and DC Fix?

Well Garry I myself have no way of measuring that but as lostplaces pointed out, the little that might be lost in lumens is more than made up for by the improvement to the beams' usefulness. None of these XHP flashlights would be very practical as they come for use as bike lights, their beams are all ringy and their hotspots too intense in proportion to spill. And as I've mentioned before, adding an external reflector into the mix improves overall efficiency so in that case there's probably more of a net gain. Just got in a roll of 4" wide aluminum tape and a 3" of copper, so will reprogram the sine wave generator to take advantage of the greater real estate when I print out new templates for my Epilepticals ™. They're actually up next on my to-do list!

And of course will post beam shots after dark.

New! Improved! Reflector Shields for Sofirn & jin heng

NEW! IMPROVED! Sofirn SP33 V3.0 JKK03 Copper and Aluminum Reflector Shields by andyXchrist, on Flickr

Fabbed these new reflector shields from 4" and 3" wide rolls of aluminum and copper foil tapes adhered to liter soda bottles.

Results much improved with the longer units, tightens beam and sharpens cutoff.

Have to say that among all the models and diffuser combos tested so far, the JKK03 4000K with 38mm Diameter Bead Surface Plastic Plano Convex Lens over the original glass cover plus d-c-fix is the clear winner. Produces the smoothest beam and plays nice with the new external reflectors. Cutoff x-treamly clear and sharp.

Was pleasantly surprised how well the new copper reflector masked the blue tint around the Sofirn's hot spot.

Once again, my iPad cannot be adjusted for exposure on the fly, and even with the flashlights all on their lowest settings the hotspots appears way brighter on camera than to the eye. But the beam patterns it captured are accurate overall.

Will try to get outdoor shots tonight if the weather co-operates, kinda iffy right now.

Finally got my fairing on!

Funny but I'd devised this Rube Goldberg setup to circumvent the Windwrap fairing slated for installation on my Stratus XPC LWB recumbent bike. Turned out that the KD BL70S I'd had on the center of the chopper bars was actually okay to use behind the clear polycarbonate, doesn't cause all that much glare inside the cockpit after all. Guess that's because with the additional reflector shield it comes pretty close to the fairing's interior surface so there isn't all that much room for the beam to bounce back, huh.

Still don't regret the additional purchases; wouldn't want to have the KD lamp alone going full blast behind the fairing because then the glare would be unacceptable. Combo of all five lamps allows me to employ each on its second lowest setting and conserve juice for extended run time - should get between 6-15 hours use out of every charge cycle. Plus can adjust angles on individual lamps to customize light carpet, from narrow single track to rural commuting on unmarked highways.

Sofirn SP36 BLF Anduril Now with Aluminum Epileptical ™ Reflector Shield

Received my pair of Sofirn SP36 BLF Andurils today and wasted no time defiling them with not one, not three, but TWO! count 'em TWO! layers of d-c-fix and my by now signature Epileptical ™ Reflector Shields. As you can see from the first ceiling shot below, the unmodified beam was kinda four leaf clover shaped - due of course to its four reflectorized Samsung LH351D emitters.
