New TerraLUX TLE-6EXB ?

[22hornet]

Hello,

First of all: best wishes for a dark 2010!

I was looking to order some Terralux upgrade kits and I found this:
http://www.batteryjunction.com/tle-6exb.html
this looks like a new version to me. It seems sturdier than the previous model that looked like this:
http://www.batteryjunction.com/tle-6k2.html (but in a different color for the "B" model)

It seems the new model is still only available for the 2-3 cell models.
Specifications remain the same at a listed 140 lumens output.

Does anyone have experience with this Terralux? (Is the 4-6 cell model soon to follow this new style? This is important to me as I need some urgently)

Kind regards,
Joris

Yeah...I just bought 2 TerraLUX TLE-6EXB and put them in a
2C maglite and a 3D maglite.....the 3D is much brighter.....they work great.

Bought them from MattK @ Battery Junction.

Hello,
Thanks for the reply. So it is actually brighter on 3 cells? So that is like the previous model. You have the new model TLE-6EXB?

They look more robust. I truly wished they made these for the 4-6 cells as well.

Keep well,
Joris

Yeah...I have the new model.....3D is much brighter than the 2C.

Thank you....have a happy new year.

3 cells is 3.6v = 1 x lithium.

im sure with a spacer and some effort you can get a 18650 into your 2xc light:twothumbs

Would that step it up to the brightness of the 3D?
Ahhhh....your saying 1 18650= 3 D cells?

yes, many people use 3 x c cells in a 2 x d mag*ight to increase voltage from 2.4 to 3.6, and they fit.

i was thinking in your 2c mag a 18560 would fit and give you 3.6 = more brightness

TerraLUX will probably release it once old stock of the TLE-6EX 4-6 cell is sold out.

Meanwhile take a look at [url="http://www.superbrightleds.com/']PR2-1WHP. Uh direct link does not work. Go to flashlights and bulbs, scroll down to the bulbs, its the 2nd button on the bottom right.[/url]. (Picture on the button is identical to the new TLE-6EXB.)
Note the 5.4 to 30 Volts DC spec. Mine will NOT light up on 4 NiMH (4.8V) but will on 4 Alkalines or 6V lantern.
Does not focus well in fixed focus flashlights. Reasonable hotspot close up but donut hole 10 feet or more out. My TLE-1F has donut hole close up but tight hotspot 10 feet or more out. Both need a Mag's focus ability.
About twice as bright as the TLE-1F.
Good for 5-6 cell Mags.

I ended up using PR2-1WHP in my 4AA light with the TLE-1F in my 6V lantern.

What kind of mods does it take to make the 18650 work in the 2 c mag ?

Is that a rebel? I find it kind of funny, that the module is virtually identical to the old MagLed design, with the new MagLed emitter. Does the the Rebel handle heat much better? In any case it does look much more robust than the previous TLE-6EX or MagLED's ever were. I alway found the old Terralux hard to tighten down properly with out it feeling like the exposed circuit board was going to break away from the leads on the P4-like it did with the first one I owned. Now If only I had a 3 cell Mag that needed one.

wrap the battery in some paper (or a short length of plastic pipe/tube) so it doesnt wobble around inside, and a metal spacer/longer spring to make contact at the end.

very easy to try if you have the 18650. :candle:

Cool....thanks.
A piece of pvc pipe would prolly do the trick. :thumbsup:

I highly doubt that the EXB model is more robust than the previous version with the K2 emitter. It has less metal and less contact with the socket. The K2 version has lots of threaded contact while the EXB version has only a thin line of contact at the flange and possibly (at best) a line of contact down one side since the drop in is smaller diameter than the socket (or else you'd have to hammer it in). The Rebel can NOT take the heat the K2 can, but is more efficient than the K2 at lower currents so it will generate less heat at the same current. This new design will likely be more efficient, but get hotter even with less internal heat flux due to less sinking (place for the heat to go) so the lower amount of heat generated will just build up with little place to go and step down drive current to compensate.
I believe the 'new' design is just cheaper to make with a few pieces of cheap stampings instead of the old larger internally threaded housing. The Rebel is cheaper too.

Hello,

I use one in a 2 d cell M@g, with a streamlight stinger (3,6v) battery. I used waterpipe insulation around the battery.

I forgot that the TLE-6EXB had a K2. I had the TLE-6EX with an SCC P4. Perhaps robust was an poor choice of words. What I mean is, I find the fact that it uses the regular Maglite retaining ring comforting. I feel more confident really gripping that and tightening it than the threaded heat sink of before. In my experience with the 4-6 cell version was sort of fragile. It had the two ends of the circuit board sticking out and it was hard to grip the module with with out inadvertently grabbing the exposed area. The first one I had, I broke the solder connecting the emitter lead to the circuit board. I found that the heat sink would rub against the reflector cam over time causing it to loosen. I also had the emitter break away from the heat sink and I had re-glue it.

As for the amount of contact, isn't that the same amount of contact that high current PR based hot wires use all the time with little issue?

ive been trying to find a little info on the new tle-6exb upgrade for a while as i was considering buying one, but after finding more or less none i decided to just get one and hope for the best, its not the brightest upgrade out there i have no doubt, but its not bad. the beam is as ugly as can be expected with the standard reflector but thats hardly the fault of the upgrade, focusing range is more or less identical to the original incandescent bulb. the tint is a fair bit cooler than the tint of my fenix l2d 100 also with rebel emitter, which i was slightly dissapointed by and the brightness is somewhere around the 100lm high mode of the fenix, a fair bit less than the 175lm turbo mode i think, but its hard to say for sure as the fenix isnt particularly narrow in focus and the maglite is pretty useless unless its focused tight in my opinion, plus as i mentioned the tint is rather different. These oppinions are based on using the drop in with a 2d mag using alkalines and nimh, i couldnt tell the difference between the two when i compared briefly. I may try it in a 3d mag if i can get one cheap to see if it really is noticably brighter with 3 cells.
... o also it does seem reasonably sturdy, i had no feelings that it was going to fall apart when i was handling it certainly no more so than the original glass bulb in any case. it didnt seem to get particularly hot when i have used it so far, but then its only been for no more than 10 minutes at a time to be fair, in that time though i could still hold on to the retaining ring and it didnt seem much more than warm. I havent even got through one set of batteries with it yet so i cant make any comments regarding battery life. My intention is to leave this light in my car when it'll hopefully be there when i need it as the light output is easily bettered by many pocketable 2aa sized lights, or smaller even for use every day, but the battery life should hopefully be good on d cells and the weight is more comforting in the hand.
Im interested if anyone has any oppinion of how it peforms against the newer rebel maglites, as obviously the components are going to be pretty much the same, though this has the benefit of remaining upgradeable further more easily. the main reason i got this over the stock rebel mag 2d is that i got some 2d incandescent mags really cheap and buying the drop in extra still made it cheaper than the new mag.

In my experience with the 4-6 cell version was sort of fragile.

Yeah, build quality may be a diferent issue. If the newer ones are built better overall, then they may be an improvement. My two of the previous design (one K2, one SSC) both seem well built and have withstood tinkering, many changes between hosts, and so on without damage or fail. I have no hands-on experience with the new ones.
I will repeat that the Rebel 'should' be more efficient than the K2.

As for the amount of contact, isn't that the same amount of contact that high current PR based hot wires use all the time with little issue?

Hotwires can get hot without damage so they don't need heat sinking. LEDs need to stay cooler to maintain life or just plain not to burn out if the temperature gets way too high. Air is a thermal resistor, so any air gap will make the LED heat up.
