BLF GT (preliminary) modding thread

Nice, but I was curious about that silver one…

Nope, the SST-90, SBT-90 and CBT-90 are the same technology. They are from 2009.
The CFT-90 is new and much more efficient at the same current (around 60% at 9A). In addition to this it’s rated for a 50% higher maximum current (27A vs 18A).

Where did those guys who ordered massive aspheric lenses from optiform go!? :smiley:

I thought I’d remembered reading that the SST-90 was also updated.

If you look it these pictures its definitively different than an old version:

new:

I am using something similar, I found a couple of para cord zipper pulls from an old backpack, they have a hard plastic coating on one side.

Is the driver which is good for the CFT90 an easy task or not?

Are there any plans for a longer battery tube?

Depends on how much current you want to drive to at. 30A will be difficult.

Got the SD75 XHP70 Boards, easy conversion to 12v, did one this morning.

Cool, where did you get the mcpcb’s?

They still say they plan to make some ready made 12V mcpcb’s once they get caught up on the GB but nice to have an option before that.

I got them from Lumintop T/A.

Personally , i would try to use a fet driver and limit the current though the led wires first .

Cheap solution , but it could work to at least get the emitter at a safe operating current .

Be very careful when trying to open it up, damaged the HALIII ?? anodizing while breaking two straps, the strapping was the only thing that touched the light, the bad news is it is still stuck, they hired King Kong to put this one together :rage:

Pass the 10lb hammer will you :weary:

Cheers David

Yeah, they can be pretty tough to get open - I struggled with another one this evening, fortunately it came out un-scathed!

My replacement light meter arrived a few days ago (Dr. Meter LX1330B), so I took a couple of quick readings after an emitter swap to a 5700k XHP35 HI D4 bin.

Taken from 20 meters, the new meter reads more in-line with what I expected; 2198 meters throw, as opposed to the old meter, which was reading low, @ 1841 meters.

oh that’s a bummer pommie :frowning:

mine is still stuck and trying to find a way to open without damaging :open_mouth:

:question:

No, not at this time. People that don’t have the light already complain about this tube being too long.

And a longer tube would be excessive I have to agree, adding even more weight to the light.

Still waiting for the host…

I have actually carried the light on trails on a sling, but noticed it would have been more comfortable if it was longer, so as to rest it on the shoulder while aiming the light.
I guess I can always make an extension just for support. Thanks.

That is a point and something to consider down the road but there are a lot of things that need to happen before that.
