Poll:1st BLF Original Ti

Ok, gotcha!

so its meant to be legoable with the convoy s2!?

Honestly don’t know, that’s for Rey to let us know. Although I’d be surprised if double the cost, as it wouldn’t be double the material.

how much it cost for S2 with ext tube?

I think the S2+ ti version with enhanced looks/features is a good idea. I voted for 18350 but would be okay if 18500 or 18650 or such is the choice. A combo with 18350 and 18650 would be nice too. Also, a request for triple compatible pills or spacers?

I vote a Convoy s2+ style with a tube to fit 18500.

I don’t see why?

I kind of like the 18500 idea, although I’m not completely sold.

Yes! If the pill threads just go far enough forward for a triple to be installed without a spacer that would be very nice.

A titanium 18650 light is going to be super expensive. I vote for S2+ with extension.

AA or AA would be my preference. I am getting less happy having potential ‘mini bomb’ batteries in my house every time I read a horror story on here.
AA or AAA battery sizes are a no brainer if you live in the UK really, it’s all we can get without going international, they are always in the drawer and if not you can buy them from the shops.
Maximum power is not always the top priority. I have a LED Lenser® P3 BM, and for it’s size it’s fantastic.

I forgot, a bolt on clip option please?

I think Rey is going to use the Convoy for the machinist to measure all sizes and internals. The looks on the outside are by no means necessarily going to be Convoy style.

Yes,just need the inner size of S2+,so everybody can mod or complete it easily.

There are many choices of body shapes,

18350 + 15 = 18500
18500 + 15 = 18650

So what we need is a design for an 18350 and the 15mm extensions that go with it and go togther.

18350 = 18350
18350 + 1 extention = 18500
18350 +2 extensions = 18650

Or did I miss somthing?

Nope. That is correct math.

You also have the problem that titanium can’t take the heat production from high powered lights, its thermal transfer is much lower then aluminum and it has low emissivity (no anodizing), hence lower power lights would work better with it

1. I really wouldn’t get hung up on worrying about Li-ion. So many things use it such as mobile phones, lap tops, digital camera and many other things. And have done for years. With flashlights you just need to be semi responsible and use a DMM to check on them.

1a. Not too mention the RC hobby is pretty big in the UK and almost all RC planes, heli’s and cars use a very similar technology known as LiPo

2. And remember petrol lawn mower, gas central heating, petrol cars are all pretty common in the UK. Do you really think they are more risk free? Are you going to get rid of those too?

3. CR123a batteries are fairly easy to buy in the UK too, any camera shop will have them and will have been stocking them for decades.

4. Not too mention you can easily buy them online and have them next day or the day after.

5. Same goes with Li-ion, in 2015 they are no harder to buy than a pint of milk.

If we are going for S2+ dimensions, then there is already two holes on the tailcap where you can fix one of the Convoy clips. Maybe it would be nice to get the clip also in Ti?

Me likey +1

:slight_smile:

Certainly don’t deny this, but this is BLF…. :wink:

Dale or someone else is bound to fit a triple XP-L being direct driven and 3000+ lumens!

That aside, short burst high output is fine if you have a UI/driver to allow sensible use too. But a wow light, should IMO have at least one Wow mode too! :smiley:

Since we have DTP copper boards, flashlight pills/bodies can become much hotter without overheating the led itself. Driver/battery overheating will happen sooner than emitter overheating nowadays. So Ti bodies are less of a drawback now.

Huh, are you not arguing that heatsinking instead of heat shedding will prevent problems?
What happens when the sink is filled?

What here at BLF is usually not taken into the equation is that for any heat path, the amount of energy (heat) that is transported is also directly related to the temperature difference between beginning and end. Given that often the ambient temperature is fairly constant, close to room temperature, if the flashlight gets hot enough even titanium will dissipate the energy, in fact the temperature will rise, more heat per second will be dissipated, until a temperature is reached where the amount of heat produced is equal to the amount dissipated. If titanium is in the way of the heat path (that keeps the heat local, close to the pill) instead of aluminium (that spreads the heat nicely over a large area), a higher body temperature is needed to get rid of the produced heat. If because of the DTP-board that higher internal temperature of the flashlight is allowed, the titanium flashlight will do fine, although it will be hotter to the touch than a comparable aluminium flashlight.
