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

Against my better judgement, signed up for 1 NW with batteries and an extra carrier. Put “maybe” for lens & reflector, cause…maybe.

What am I missing with the extra reflector option? I understand how a lens can break or get scuffed but it seems the reflector is pretty specific to this light and not much risk of being damaged… Considering how many people seem to want one I must be missing something though so feel free to point it out to me.

It is basically a chance to get a 120mm reflector for custom builds. Many many people asked for it in the first group buy but since they could not even get enough reflectors for the group buy lights obviously they could not sell them separately.

I promised to try and make the reflectors available later and this is me following through on that promise. :wink:

There is really no need for an extra reflector for most people.

What would be cool is if Lumintop could offer a “premium” version of the reflector. Slow cut, hand sanded to a super smooth finish. It adds time and money, but maybe there are buyers?

Until TA and Jason open the BLF machine shop in Houston i guess i wont be needing spares.

I would be in for it. Might as well go all the way for a light like that but I doubt Lumintop would agree to doing it.

Yeah, I don’t see them offering a better reflector, they had enough trouble getting this quality. The reflector itself is actually fine, the only issue is the coating process and it is quite difficult to get reflectors this large coated perfectly. Better sanding would really not help much.

Signed up for 1, NW, 8x30Qs. Hopefully we can get the bag n lens cap offered with it and no extra $20 shipping to Oz!

With the right rigid work and tool support, chip evacuation, coolant/lubricity, speeds/feeds/ tool geometry negative/positive/zero and tool tip radius PCD is the way to go to obtain Micro Finish Surfaces with alloy’s. Most don’t even hone cylinders/crank/cam bores any more, they are Micro Sized and Finished with Diamond PCD runners and plain (within a certain lubricity) coolant. Aluminum cam caps on Overhead cam heads single point PCD boring (semi finish) with micro finish carbide,diamond encrusted runners (mirror finish) (Mapal) brand name we use. No more Stones and Honing oil.

All for naught if you cant prep the surface and apply the coatings correctly……

Is there a preferred/easy way to open Giggles?

I hope the conversation kit will be completed with reliable instruction how the head be opened.

This instruction should be mandatory, as well as indication of the level of knowledge required for this replacement.

Opening the head is a matter of brute force unscrewing it from the switch area. No tricks to it, just brute force.

I would not cound on a manual for the conversion kit, they are hesitant enough about even offering them for sale and would love any excuse to not sell them.

Far as the level of knowlage needed, this is one of those cases where if you have to ask, you might not want to attempt it.

A basic rundown is:

remove driver retaining ring
Remove switch retaining ring
Remove head/reflectore
desolder the LED wires from the driver or mcpcb
remove the driver and mcpcb

reverse the process.

The hardest part is opening the light followed by soldering to the mcpcb. This can be quite difficult if you do not have a good and very hot iron.

I plan to bypass all of the springs, but I’m wondering if it’s advisable to wire/braid bypass at least the main contact spring when doing the mod kit upgrade?

Bypassing all the springs it is unknown how the LED will handle that. It is possible it could be over-driven then. I would not recommend it.

I am not sure what you mean by the main contact spring? Talking about the “button top” spring on the carriers? Yes, if you were to only bypass 1 spring that would be the one to bypass.

Yes, that’s the one.

Ok, I got the list formatted for HTML and while it is not perfect it shows how many are signed up.

The totals are at the top of the list.

We are at 121 Giggle Monsters reserved right now!

Not bad at all, if we can keep spreading the word at this rate we just might be able to see what that 500 unit discount would be.

I do not have any Social media accounts and do not use Social media.

So feel free to share this thread all you want or even copy/paste from it if needed (although linking is preferred).

Might want to add this, or some version of it; to the ’Conversion Kit’ section of post 2.

It might save some pain & heart ache as well as misunderstanding further down the road. :slight_smile:

A good description too I might add…… :+1:

This blf gt xhp70.2 is very promising. It got TA driver, DTP MCPCB, and p2 led bin… I measured 7500 lumen @ turn on and 7000 lumen…

Yep, his light is very close to the final production version minus the exact LED spec.

Although keep in mind that the readings done like this are lower since some of the light escapes around the edges. I measured this exact light on my sphere using an L6 reflector so that I would capture all of the light and the numbers were about 10% higher.

Hence my 7500 lumen rating in the OP.

Yes sir. I may not get the best accurate reading… my light tube is a little bit too small… this light is definitely the best xhp70.2 without spending $600-$700.

This blf gt is a perfect host for the single xhp70.2. You will get plenty of runtime and excellent heatsink…
