Mod: Small Sun ZY-T08 Emitter Upgrade - MT-G2. Now you can call it a Small Sun

[dthrckt]

nice mouseover beamshot!

I’m really loving these MTG2s. very usable beam…

Wouldn’t using T13 be easier? It’s already in series, 8.4V, but similar head and reflector. No need to mod that.

Heck, you might even use T13’s stock driver with only resistor. As far as I know it will buck voltage to match amperage, so 6.0V should be easy to get from its 8.4V supply.

Anyhow, looking forward to see the MT-G beamshot.

Yeah, the T13 would be easier, and you might get the stock driver to do it too. I do not have one though.
Also, I wanted a (jacket) pocketable flood light with some throw left over in a massive spot. Worked out perfectly for me.

psst… i’ll trade you for one of my T13

OK, you ship the T13 first… then…

Now I know not to underestimate beam size - that shot is just impressive.

Very useful - wide beam, wide spill, and the colour reproduction is very good too. Very nice mod, in all.

[Old-Lumens]

Great Mod! Boy that 5000k looks more like 4000k doesn't it? Very yellow/brown looking.

[relic38]

It looks a bit more neutral in person. I consider the tint slightly cooler than a Nichia 219.
This light is very useful. The spot is huge so as a medium range searchlight it works well. It cuts through haze so the beam itself isn’t in the way. The spill is great, nicely even and wide.

Lumens: 1820… WOW! 8)

It looks like you’ve created the perfect compact flood monster. I love your driver mod. How long can you run it on high before it gets to hot or the cells start to sag?

[relic38]

I forgot to add that to the post. The driver has thermal protection, so it steps down after about 5 minutes or so. Without the resistor mod it should go longer.
I will do a thermal test tomorrow and update the post.
This light is very useable on medium, which would run for about two hours.

[dthrckt]

did you measure the 4.5A at the emitter or is that estimated from power in to driver?

[RaceR86]

This turned out sweet! Nice mod thread Relic38!

[CheapThrills]

I like it 8)

I recall measuring it, but was a while ago. I may have to do it again to be sure. Another reason to write the post when it is fresh in my mind.

[Hopback]

Nicely done relic38, thats yet another mod that I plan to do!

(I knew that I should have bought more than two mtg2’s )

Came out great! Good idea, Great Job relic38! I thought I might not be the first - the T08 has a nice size reflector, 2 batts, cavernous driver area, good heat sinking, exc. host for this, or experimentation. Just finished a de-dedomed XM-L2/SinkPAD high amp T08 - came out well.

[dthrckt]

This is bad.

I am beginning to want 2 of so many lights - xml2 and mtg2 0:)

[janko.hrasko]

genius way of making the batts in series love the blob idea, the tint, output…
I will probably just get sinkpad in, already has xm-l2 u2 1c

[garrybunk]

Wow! Nice mod relic! How about the Small Sun ZY-T16 as a host (basically a T13 with 26650's)? Or maybe put an MT-G2 in a bike light with a 2S2P battery pack! That would make an excellent cycling light!

[Tom_E]

relic38 - man, that solder blob trick is cool. Don't think I could have done all the stuff you did for converting parallel to series... wow. I see you solder wicked the springs - makes a measurable difference on the two T08's I mod'ed - seen that over the weekend.

[djozz]

That looks indeed like small sun! Well done. As I see more mods done with the mtg2 I am really growing into this led. If they only were not that expensive to obtain....
