Modding a Trustfire TR-A9 - It's done, Beam shots are Up.

A little music while you read,

 

Well you already know I am going to mod the TR-A9. I'm not going to do a whole lot with it. It will have an XM-L2 T6 3C in it, with a DrJones driver and I probably.... maybe....  possibly....   won't drive it too awful hard. I'm not even sure if it will be 4XAA in series or 4X14500 in parallel yet. I guess I will just wing it and see what flies.  I want to make it bright, but manageable and an everyday user.

tra9a1a

Hare's the light broken down to it's basic components. The "pill" houses the led, driver, smd switch and the back side of the driver is the upper contact plate.

 

 

tra9a1b

The star is glued down with adhesive, (probably Fujik). The heat sink is aluminum, but I don't think it's anodized. I think it's painted black. I will know for sure later on.

 

tra9a1c

With the driver off, you can see inside the pill. It's hollow for the driver and it's fairly thin. I will need to work on that a little.

 

tra9a1d

Driver

tra9a1e

tra9a1f

The back side of the driver board is the upper contact plate.

 --------------------------------------------------------------------------------------------------------------

I worked on the light some more tonight and I also want to show how the heat sink/pill fits in the light and where it makes body contact.

er34r25ht

The pill is in the body.

qwe345y5

Without the body. You can see the areas where the pill sets in. There's three of them (only two shown here). The fourth is cut away more, for the switch.

 

cxvbv8t

I stripped the driver components and soldered on the pos and neg so I can wire to the new driver. (That's some ugly AA that I gobbed on the solder joints, just before it got too hard).

 

fhfhuj7876

The contact plates were already modified. If I didn't know better, I would say the original set-up was 4S not 2S/2P. I didn't have to do a thing here.

 

a9kgerr6

The pill is back together. I added a few grams of metal inside it. Wired up the DrJones driver, with 2 extra chips, so it will be over 3.5 amps and buttoned it all back up.

 

a98hg568

I didn't change the led, since this is already an XM-L2 and the tint wasn't bad at all in the stock light.

Tested and ready to go...

 

Tomorrow (today), I can do the cosmetic mods and finish the light. It will now run on 4xAA NiMHS in series. 

 

Here's the finishing shots. The light is done.

a9gl1

a9gl2

a9gl3

a9gl4

a9gl5

That's it. It turned out well and it wasn't hard to do. I used Fujik around the pill so when I pushed it in, it would make better contact with the body. I still think it would be a better light for an MT-G2 than the EA4 would be.

 

Beam Shots 

These are all mouseovers. I used the shots from the original A9 and the modified A9.

The MODIFIED light Photos are Mouse Out  and the Original photos are Mouse Over. The same settings were used in both shoots.

a9mo1

a9mo2

a9mo3

a9mo4

a9mo5

I think I done good. It's brighter than stock. It heats up Fast. That tells me the heat is getting to the body like it should.

That's all Folks.

That heatsink is kind of meh compared to what I was hoping. Don't think this is worth dropping $40 plus. Can't twait to see how this turns out though.

Well considering the wall thickness and how it sits in the body, it's about 10 times more surface area than the EA4.

I'm sure it will come down in price, but I would still rather mod this than an EA4. I will have to take a photo showing how it sits in the body.

I’ve just finished listening to the video and now you tell me your nearly finished? Are we in some sort off time warp? I’m sure I read somewhere that it was hot and you may take awhile to finish this as you may only get an hour in the morning. Or am I asleep and dreaming?

I like to bitch. If it ain't worth bitchin about, it ain't worth doin.

Besides, it was an easy build and it cooled off after the front moved through.

 

The light is done now and I will do beam shots tonight.

I saw this pop up on Fasttech.  First thing I did was check BLF, and of course OL has one modded already Smile

This is like the SRK with a momentary switch, correct?  Do you just unscrew the tailcap slightly to prevent parasitic drain?

It has a momentary switch, but the tail cap has nothing to do with ground. The circuit is complete without relying on grounding the body. When you have four cells in series, both the positive and negative end up at one end (the top), so the driver/contact plate has both positive and negative in it and the circuit is complete. You can't isolate this light unless you take out the batteries. (in stock form, or modified form).

 

EDIT: That is why the EA4/8 has a clicky and smd built right into one switch. The clicky shuts it off (isolates) and the smd controls modes.

How do you remove the reflector? I have the bezel off and the o-ring that surrounds the top of the reflector. Do I need to remove the switch for it to come out?

I have slept since then.Wink  I think it just came out by turning the light upside down and tapping it on the table, (with a rag under it for protection).

Got it! It took a bit of careful prying with a small flat head, I think the plastic led centering thing was holding on tight.
