I made another 219 triple a couple of weeks ago. This time in a cut down MM with a NANJG 7134*4 driver with 4 extra 7135s on the LED side. I was going to cut it down for a 14500 but went with a 14650 instead. I kind of like the slightly larger size.
The problem is now I need to do it again with...
What your seeing is the spill from three emitters off-center in a single reflector. All of my triples show the same beam patern. It's most noticable on a white wall with the first two I made, I left the plating on the reflector alone on those. With the Nichia I used steel wool to strip the...
Netprince,
Sorry, no beamshots at this time. If I have the time I'll take some comparing the various TIRs I have for this light.
The elliptical gives a wide, flat beam with a clean cut off on top and bottom. I like using it on my bike because it lights the sides of the road an doesn't blind...
Nice build!
I did a similar one a few months back. 3/4" copper with an XM-L at 4.2a and TIR. I used a Carlco TIR optic holder to properly position the TIR above the star. I found it gave a better beam than having the optic down on the star. It takes a little trimming to get the holder into the...
I don't think kids do that anymore, at least none that I've seen. After storms like this we used to hit the streets and make money all day. Same thing with cutting grass in the summer.
I grew up in Medfield, when they were building 27 in the mid 70s the racing on Friday nights was like clockwork.
My protected 18650s (AW) won't provide 5.0A though they're supposed to be capable of up to 5.9A. I've been told it is due to the type of driver I'm using.
I use AW IMR cells which have no problem at all.
Re: How many people use job weld
+1 On the previous response. I've used JB Weld for years and think it's a great product. I've used it on one flashlight I built for myself. I would not use it on anything for a customer without clear disclosure though.
I don't think the reflector increases the throw at all. It does present an interesting patern when about a foot or two from the wall but it dissapears at any distance.
The drop-ins handle the 5.0A (5.3 with the 18650 IMRs I got today) without any problem so far, I'm wondering how long the S/F switches will last though. They're only rated at 3A but I only run them on high for short times. Even at medium (1A) it's enough light for most uses.
3/4 id pipe fits the...
You're right about bridging the star, it's a pain. The wires are so short and have to be just right so they don't interfere with the optic. For the Nichia (the last one I made) I used a 20mm parallel star from Illumination Supply. I had to reflow the LEDs on (my first time doing that), I was...
