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

It will tint shift warmer and a bit yellow / green. So it will get worse, how much I can’t say as all LED’s seem to dedome a little differnt and will depend on the person.

If you plan to dedome I would go with the CW or replace the LED with something of your choosing while you are doing it.

Now I’m really in doubt. I don’t like CW in any of my lights. I have a DX80 just for the sake of raw output, but really hate the tint. I wish I could get two MCPCBs with the different LEDs to test it out. I have a L6 with the N2 3A and really like the tint.

Yep… what TA said. :frowning:

Take a look at the tint chart below. Notice the B & C tints are above the dotted black line (BBL). They both lean toward the green tints. The further above the line the greener. :frowning:

The A & D tints fall below the BBL and lean toward a rosier tint. The further below the BBL the rosier.

I would say the best option is to simply order an LED you know you would like from another source in your case and install it before converting the light.

I think KD has some A and D tints available IIRC.

Hmm I see. My L6 is 3A. Maybe that’s why I like it. Well. Now I will just do a little more research to try and decide it.
Thanks teacher.

Yeah. Maybe I’ll need to learn how to reflow LEDs. I’ll try and find some different LEDs on china. Thanks TA

This is what I do to basically every light I get anyways, I think I can count the lights with the factory LED’s on one hand lol.

Thanks bro… your lumen specs are really helpful.

I was a little surprised that the output tapered so close after just 30 seconds. Initially the 30q have quite the spike in output, but they fall off pretty fast.

Single emitter with so many cells had to be a factor too. Differences between, say, a 30q and a vtc5a are pretty noticeable on a triple emitter single cell light. It’s more when you approach the current limit of the high drain cells that you see the higher output from them.

Happy to help.

It also has a lot to do with the heat. The first 30 seconds of losses are largely a matter of things heating up and that causing a reduction in output if I had to guess. The 30Q gives it more power but it also heats up more, so it seems to balance out.

Right, if we assume the GT70 draws 10A at 12v, then with 8 cells it’s only 5A per cell. If you only use 4 cells it’s 10A per cell.

The difference in voltage sag between the 35E and the 30Q is not so big at 5A, but at 10A the gap gets bigger.

I think 4A and 8A is probably closer to reality, but I use 5 and 10 because we can see that in this load chart from HKJ.

Even with the sony vtc5a, the lumen drop fast from 0 sec to 30 seconds.

This is not true according to Leo at Lumintop. Here is what he replied today when I inquired about when my caps and straps would be shipping:

This makes no sense because on 08/13, I asked Lumintop about shipping the items together and was told:

And then on 08/17 when I had order issues with their site, I inquired and was told:

I paid for the accessories nearly two weeks before the light shipped. The irony is $28 was $6 more than my total which I assume was to cover shipping costs. I don’t see where I can get 4 caps and 2 straps on Banggood for $28 shipped. I realize these are accessories, but I am still making a purchase from Lumintop. Is there any BLF pull that can help get this straightened out? I don’t mind paying for shipping, but there is clearly a considerable difference in price on accessories between our BLF/Lumintop buy price and Banggood. I feel really uneasy now spending another $220 for the NW version with such fluid transactions.

Wow, I’m glad I waited and didn’t get a BLF GT yet, where can I order one of these beasts at?

Wow…. Seems like the acessory purchases are ’all over the map’…. with nobody knowing the real story. :person_facepalming:

But why do you feel “uneasy” about purchasing another light??

Did you have problems receiving your GT70 also???

Just fill out the p reorder form in post one.

If you want the cool white version I can send you the code right now. If you want the neutral white version they will be available in the next two weeks and everyone will get a PM with the purchasing details when they are ready to go.

I’m interested in the cool white version, I just filled out the form. Glad I didn’t miss out on this group buy like I have the last two, the BLF Q8 and the BLF GT. Love my BLF Q8.

I assume each one of those messages was on a different date. So maybe the situation has changed over time. Let’s let TA look over the info tomorrow.

I personally don’t know enough details on the bag stuff. I know Lumintop does not make bags, caps and straps so they have to source them from outside. Maybe it’s from Neal? It’s possible the stock at Lumintop ran out and they are waiting for another shipment. I don’t really know. TA probably has the current details.

Okay, I’ll send you the instructions.

Did you get the confirmation email? This is how you will get back to your order.

I got the Google Forms response email if that’s what you are talking about.
