The BLF GT70 "Giggle Monster" is here! 7,500lumens, 1,500m throw! Group buy Closed!

At full brightness, that is about right, although it is direct driver so it will be dropping brightness as time goes along.

Remember the above estimate were till LVP, aka the batteries were dead.

Some basic math says we have a total of ~6000ma with both cell carriers filled with 30Q’s.

If we are pulling 9A, then on paper the cells should last around 40 mins.

Although in the real world with the power dropping 20 minutes at turbo before you notice it dimming is a good guess and then keep running for another hour+or so until it hits LVP.

Summited the form:

1 conversion kit.

4000-5000k

8 30Qs depending on price.

May be interested in a spare lense.

a lot of people have asked for reflectors since this project started, mostly for custom lights I think.

So, when are we going to push for a triple mcpcb and reflector? :smiling_imp:

Will the MCPCB be copper for the 70.2? I’m thinking that should better protect the overdriven 70.2 and can maintain higher lumen output.

Yes, it will of course it will be a direct thermal path copper mcpcb.

Only triple?

:innocent: :innocent: :innocent: :innocent: :wink:

Except 90% of the people won’t want to try and open up the light. I would just like a swapable head and not have to get out strap wrenches and struggle with it. Was hoping for the same thing with the BLF Lantern. Multiple battery tubes and carriers are redundant

I actually meant to say reflector but typed lens. I see TA’s answer already.

I don’t agree. It all depends on how you advertise it. If you advertise it as a light with an interchangeable light engine then most people will want to be able to change it out for a different light engine.
As I said it was partly designed for this reason.
And if I’m honest we (as GT team) and mostly myself let that feature slip away. If we had communicated that feature to lumintop from the beginning we might already have a xhp70.2 light engine. But that’s the problem with these projects it’s not that easy.

I can’t recall if the light engine was as tight on the reflector housing as the bezel was?

1x GT70 NW
1x conversion kit NW
Maybe spare reflector
1x spare lens
8× 30Q cells

1x GT70 NW
Maybe spare reflector
1x spare lens
8× 30Q cells

About the same. The bezel has lots of friction, but the light engine is just “tight”. Once you break the initial tension, it just spins off. You don’t have to install it super tight, either.

When you seperate the upper and lower head it makes the bezel much easier. I can take my light apart completely by hand.

Everyone buying a kit will still have to take the light apart to do the emitter swap so I don’t understand not selling a complete light engine.

Yes, they are silly both silly tight, better then being glued but still, just silly tight.

this is the only reason I didn’t push a new light engine, I already know of quite a few people that can’t open their lights at all and having opened a few myself, it ain’t easy and almost impossible in some cases. Not something I like doing.

I modded a few of these last week with the mcpcb’s I had and I offered everyone that sent the lights in the chance to save some money by opening the lights themselves. All of them paid me to open it.

I am going to need to get a better strap wrench if that keeps up.

I think a light engine replacement would be nice, depending on the price. Include a nice little plastic case like for a camera lens to keep the one(s) not in use protected and clean.
Once you get the light apart once, theres no need to tighten it up as much as it is from factory

Which is exactly why having an entire swapable head would be great. ie: a GT70 minus the battery tube and carriers. Personally, I won’t buy it unless just the complete head is available.

What your saying ONLY makes sense if the head was much cheaper than the whole light. But that is not the case.

If a complete head is still 90% of the total price you would only be saving 10%. It makes more sense to have 2 complete lights then you don’t have to swap anything. Maybe you could even sell the tube and carriers.

Filled the form,

–2 or 6 spare reflectors (lets see the final price).
–1 spare lens.
–30Q batteries depending on price.

Question is, could I get this items without ordering a light or conversion kit?

Yes, we talked about this for a little bit but basically the savings of not having the battery tube and carriers would be so small it would not be worth it.

They would have to either order mis-matched quantities of the heads and battery tubes or be left with a bunch of extra battery tubes they can’t use.

And the buyer would end up with 1 and a half lights while saving less then the cost of shipping. It is inevitable that many would later want to buy another batter tube and carriers as well further complicating matters.

Yeah, to me a ‘head only’ option is just silly. And personally, I can’t see many people interested in that high priced option. Just get the whole light.

However, a light engine option makes sense for those who can’t solder. Cause either way, conversion kit or ‘light engine option’……… the light engine has to be taken off.

Just make it crystal clear that it can/might be difficult to remove the light engine initially. :wink:
