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

Ok, just a few questions:

The throw claimed is with the de-domed LED, but the led will come dome-on, as I understand it. What would be the throw of the GT70 stock, as it comes from the factory?

The driver used would be fet+1+15, instead of the original buck driver. Is that correct?

Thanks.

FWIW, I think the claimed throw, candela, and lumens should be given as it comes from the factory, not user-modded. Making a note of the expected throw after dedoming is great, but is not how the light comes stock.

Lumintop should make just a complete head available so we can use our existing carriers and tubes. That would help keep the cost down a bit.

I was thinking of just the lower head, the light engine. Then your not paying for the expensive reflector, etc… and the shipping box would be much smaller and lighter.

This.
It would be perfect of they can offer the light engine with a xhp70.2.

Actually, the reason the head consist of 2 part is partly due to upgradeability. Not only for modding purposes.
Creating a easy and, hopefully much economically, way to upgrade the light with newer or different LEDs.

Would be cool if they would make a dedome option from factory. I mean Acebeam also does it on the K65.

[MRsDNF]

2 x battery carriers and lenses.

Nice work guys. :+1:

[ZozzV6]

Filled the form for a neutral mod kit.
Or the lower head light engine if turning out to be that way.

I have been using the short tubes on my GTs. Those of us with short and long tubes could make use of spare parts if we were able to buy:
1.Complete head
2.Tailcap
3. Battery Carrier

I would imagine quite a few of us have GTs already with both battery configurations and would like to have a lower cost alternative to make 2 complete lights.

Keep in mind that Lumintop has not built this light yet, so there’s not even a prototype to get measurements from (AFAIK). There are only the several modified GT’s that TA has built and measured.

I have asked TA what specs we should post for the dome-on led. When he wakes up, this info will be updated along with a driver amp draw. It currently says 2.5A @ 12v, but that is a carry over from the original GT spec. The new version should be closer to 7A to 9A range. Plus it might vary based on whether one or two carriers are used.

Before he sliced the dome off he was getting around 1100m to 1200m throw iirc. I can’t remember if that was with all springs bypassed or not.

Dont worry, these specs will be updated soon.

Here is what TA said about it on another thread.

@Texas_Ace

@JasonWW

If they do a driver and emitter, then it really would be an easy swap. Now I am getting interested. I wonder if they can slice the dome too.

I am not sure I would trust them to slice the dome. It is not something easily done on a production line.

It is a simple mod for people to do themselves, though.

[quijibo]

I’d like to go in for two:

one neutral white
one cool white (could not indicate separate color temp on form)
Also 4x extra carriers
No lenses, conversion kits, or reflectors.

Thanks!

A complete head could very well cost 90% of the total lights price. So would you really save any money?

I don’t know the exact number but the cost of the head is by far the most expensive part.

I am in for 1

Sadly the savings of leaving out the battery tube and carriers would be minimal, maybe $30, the bulk of the cost is the head so it doesn’t make a lot of sense to sell it separately.

Remember that both the head and the reflector start out as big solid hunks of aluminum, that is a lot of cost and machine work.

The issue here is that many people have a big problem opening up the GT, so it could lead to more issues then it fixes. Otherwise this is what would of been offered instead of the kit.

@JasonWW

TA, here are a couple of reflector pictures that you can use in the Google form.
.

Thanks, I will update that in a little bit

[teacher]

Impressive way you are setting this up TA!! Very impressive compared to previous Group Buys…. :+1:

Google Form submitted for:

• 1 x BLF GT70
• 2 x Conversion Kits
• 2 x Battery Carriers

• Interested in lens, reflector, & batteries
  …………

Also if Neutral White is between 5000K - 5500K that will be good. Otherwise CW for me.

…………………………………………
From Google form

Neutral white - 4000k - 5500k
Cool White - 5700k and above
Warm White - 3700k and below

That was a mis-understanding. The specs in the OP are in fact approximately what the final numbers should be as delivered from lumintop with the dome on.

In fact I am actually under-rating them since we do not know the exact LED model yet. If for some reason they can not get P2 bin emitters, then the numbers might have to be adjusted. We will know more in a week or 2 when they find some LED options.

I tested a P2 bin 5700k light just yesterday and the numbers posted are a good bit under-rated from what I got to give some wiggle room.

It is a TA V2 driver that replaces the 7135’s with a resistor bank. 7135’s die at 12V and do not like 6V so I have to find another option and after a lot of testing and prototyping this has proved to work very well.
