[PART 1] Official BLF GT Group Buy thread. Group buy officially closed! Lights shipping.

thanks, just what I hoped for.

Edited the image above ;)

Nice pictures on the balance point ARsee. Thanks. :+1:

I could have done better if I put the camera on the tripod LOL!

Yeah, I’m still waiting (patiently?) for mine, but so far no news :frowning:
A friend who lives 200 miles up the road got his almost 2 weeks ago so I was hoping I’d get mine soon.

200 miles up the road, haha great, in my country you’re already outside the Netherlands.... :)

For all waiting, I heard that professor Lumintop made the reflectors nearly perfect now. (It’s a rumor in Guangdong, not know if it’s really true...)

If it boils down to the entire process teaching some new techniques that improve the product over the course of this group buy, would it be possible in the end to purchase a new reflector or other parts? I don’t have an issue with my reflector, but am sort of on the OCD side and if there’s a “near perfect” one being made at the end of all this I’d sure like to procure one.

I know Lumintop will want to sit down and take a breather at the end of this, and of course I’ll be in no particular hurry, just saying that it’d be nice if some parts would be individually available. :wink:

Seems to me it would have been beneficial to stick to a pre-determined final quantity for the group buy. Be that 555 or 250 or whatever, it did seem to go on a long time and at the back end of it all the numbers of people signing in went a bit crazy. I’d like to see Lumintop make money on these so they will be happy to work with us in the future, hope this “ordeal” hasn’t soured anything.

+1 Dale

Plus one.

I have not been contacted on how to pay yet…… should I still be waiting or did I miss something?

Doh!……
The next group (3rd batch) to purchase lights (#1050 and up on the list or who signed up after 10/23/17) will get their emails late January to early Feb in order to let Neal get caught up with current orders.

Sorry….I am retarded……watching LEDs turn on, probably isn’t good for my brain…

This reminds me one senior manager once told me he has to spend 4hours everyday just to read and answer emails. Besides quantity is very discouraging, it is also finding correct information part that’s time consuming and might need to confirm with third or fourth persons. Imagine you have to reply all these.

beamshots.
we need beamshots…. :stuck_out_tongue:

Yes. Less talk, more beamshots.

I think this might actually work with a high powered LED light with enough battery capacity and good thermal endurance. The bowl should preferably be matte black to better transfer heat to the bowl and to cause less overheat to the actual light engine. An insulating layer between the edge of bowl and head would have some effect, but I don’t know if this would be beneficial or not.

Let’s not make this too straight forward. :smiley: This could even work without dismantling the head. Just have a suitable light absorbing thing you want to heat. Not necessarily a bowl, even canned food or a bag that can take the heat(there’s liquid inside when heating, so even a plastic package might survive). Aim the light and insulate package from other directions. Apply until ready to serve.

The latter method would of course only make use of the radiated energy and not the bulk that’s generated in the light itself, but it might be enough.

On second thought, maybe not. Thinking in terms of wattage required to effectively heat food on a hot plate, what’s enough? I think a coffee machine hot plate is in the range of one hundred watts or slightly less, so one would preferably need all the heat from a high powered flashlight, not just the power of the beam… but I don’t know. My intuition is it’s just on the threshold of being usable or not, and I can not decide without experimenting or at least making actual calculations. Even compact lights are pretty good pocket hand warmers but heating up soup - essentially water in sense of thermodynamics - is a way harder task.

I know, the GT is not something most people would take on actual camping trips, but an interesting idea. Just like the idea mentioned earlier in this discussion: it kinda almost floats, but doesn’t. Might not be that close to a density of 1, but closer than pretty much any other flashlight with durable aluminium construction. If it had been upscaled even further, it might float. :partying_face:

Hoping that is true after being jealous looking at the tons of GT pictures here

Keisari, Kawiboy is pulling 22 amps through his 6V XHP-70, figure the wattage on that little oven why don’t you? :slight_smile:

Tomorrow a couple of friends from here are coming up from the coast and we’ll be doing an emitter swap in their GT’s. I have mine and one I bought for a gift so we’ll have 4 GT’s to play with. Plan on getting some photo’s. :wink:

How do I see this. :smiley:

/\\\…. :smiley: … :+1: … :beer:

Including that tripod adapter for the strap was a really good idea. Earlier I posted about making sure there’s enough depth so it wouldn’t have the problem I have with my Q8. By including the adapter, they bypass the issue. I doubt they caught my comment, so kudos to them for thinking ahead.

Okay, the my is coming by FedEx (Yes, not DHL) on the 23rd. No email from Neal, but a message straight from FedEx instead.

Normally 11/2 times the diameter for the depth of thread, 1/4-20 x 1.5= .375” (3/8”) is pretty much a standard minimum of thread engagement unless other wise noted by engineering. At least where I work.
