Review: Ultrafire 602C DIY LED Flashlight Host

I just built a second one of these up for a friend: 4x 7135 101AK driver set to 3-modes with U2-bin XM-L emitter.

But!

When I ordered the parts, I also ordered a pack of these:

http://www.fasttech.com/products/0/10001923/1182004-insulation-gaskets-for-cree-xm-l-t6-led-emitters-1

...which worked perfectly and assisted in centering the stock reflector. I didn't have to dig into my box-o-parts this time to get a properly-fitting reflector.

I almost ordered some of those when I ordered this light. Guess will email FT and see if they can put it on my order as they have not shipped it yet.

Thanks for the info!

Got my parts today:

There’s a black paper insulator but like keltex, I use the same insulator gasket he posted.
I also need to solder the driver as it is also loose on the pill.
Can’t remove the tail cap. Might need a vise but no reason for me to force it right now.
Light blue switch cap and not protruding so no problem on tail stand.
Easy lego! Nice pocket torch.

Blue cap? Mine's a GITD green! Also, on this light, the body/battery tube is the tailcap; the switch assembly threads into the bottom of that tube...

I looked again this morning and you are right Keltex. It’s actually light green
mine. And thanks for confirming to me that the body/battery tube is the tailcap!

As planned, I built myself the first nichia 219 light with this host, a nichia 219 on 10mm star, and a 5*7135 driver from fasttech. It works great. I set it to 3 modes. the low is very usable being around 15-20 lm. The high is around 200lm (compared to trustworthy fenix LD20). The clickie feels good. The size of the host feels just right in hand. I prefer clickies much better than twisties, even for EDC.

The only complaint is that the isolation disk came with the host has a hole that is too big. It is about the same size as the opening of the reflector.

I just ordered one last night. I’m curious, does the reflector work well with a Nichia? I have a few 219s as well as a few CW XM-Ls, I’m leaning toward a Nichia at 1.5a or so.

I bet they will work good but I personally dont know. That sounds like a nice combo let us know how it works out!

I still like the heck out of mine!

I did one with a Nichia, works great. Nice beam.

Nichia it is, thanks.

i bought one as well, put an xp-g2 and a 3x7135 ak47 driver in it. i don’t know how to keep the led centered though? How have others done?

not sure if i like the mode spacing on the ak47 though, medium is a bit too high for my liking.

I have had this host with a nichia 219 for about 2 months now and still loves it.
Just want to update that the anodization on this little guy seems really good. It has been carried in my pocket with keys and does not even have a scratch or ding yet. Definitely a lot stronger than solarforce L2m (Type II ?). This might have Type III.

Just got in two of these. One will be used for a TV-B-Gone, and I built an EDC last night with the other, using a XM-L U2 and a 4x7135 Nanjg 105C driver.

I found I couldn’t screw the pill far enough into the head to make room for the body to fully screw into the head. Ended up leaving the front O-ring out. Also took a while to get the reflector lined up inside, as it’s fairly loose.

Did you see my post further up this thread?

The reflectors I linked to there are a perfect fit which makes centering the emitter much easier...

Ordered a couple, thanks!

After being lost by the local post office and found again, the DX reflector came in - and it sits quite nicely in the head.

But even with the new reflector, the O-ring/glass/pill/reflector stack is still too long to permit the body to screw all the way into the head. Once again I’ve left out the front O-ring.

Oh well…

Did you file down the solder blobs? Also it is not hard to sand down the bottom of the reflector a little.

Solder blobs are filed down, I’m using kapton table on the reflector for insulation, and the thickness of the wire insulation is probably the limiting factor now.

I s’pose I could file down the reflector or make the pill thinner somehow, or find another LED on a thinner MCPCB, but meh. I’d rather not have to modify a host to make it work. Though I s’pose you get what you pay for - most of my experience with cheap lights has been great and I’m probably expecting too much :smiley:

Still gotta say I like the light and I use it a fair bit - it’s my “walk to the neighbors” / “take the dog out” flashlight. Gets the job done.

I still love this light! Its been my EDC ever since it was built! The 4 mode driver from the group buy of the A8’s is still perfect for this host in my eyes everything just works together like peanut butter and jelly!

My 602c with a nichia 219 has been my daughter’s chewing toy for the last 3 months. It is still working flawlessly. :slight_smile:
