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

I think you’re right. Only the silver oxidizes very fast to it would have to be coated with clearcoat where we are again with orange skin

Absolutely. That wouldn’t be hard to do Alux. Even if it’s a coating of aluminum it’ll oxidize so that should be coated also. Clear coat might be more of a problem with a telescope due to the absolute requirement for accuracy. But I’m out of my knowledge base when discussing clear coat. It would be far easier to clearcoat a flashlight reflector though since we aren’t discussing fractions of a wavelength of light. Maybe the same AR coating that is put on a lense would do it? I’ll leave it to the manufacturers to handle. :slight_smile:

Would it be worth doing for the slight gain in output? There might be less expensive ways to get that gain then by silver and clear coat.

Just brain storming now… I was thinking platinum also, but I didn’t look up it’s reflectivity. That metal doesn’t oxidize. Of course we’re back to cost and I have no idea if it can be vapor deposited. Gold would also work. I know gold can be vapor deposited. Just look at a NASA astronauts face shield. Again, cost.

I would like to extend a special thanks to Lumintop for the great work they have done from the day we first contacted them right through today. The amount of work they are doing is unbelievable. Their expertise is immense. It is obvious Lumentop is an excellent manufacturer. We are very fortunate they are making these lights for us. They make it very clear they are willing and able to do the most possible.

I don’t know how everyone else feels, but if it took a year before my light came, because that was the time needed to make it as perfect as possible, I would be delighted they took all the time needed to do it they way know is best. It takes as long as it takes.

Was that through DHL or registered mail?

Y’all make the reflector plating process sound simple. It’s not. The final finish used won’t stick to the raw aluminum as machined, so what appears to be brass is applied first. This fills the machining marks, normally, and leaves a more perfect finish for the final reflective coating. (Yes, I’ve hand sanded the coatings off down to bare metal too many times) At any rate, the people who make reflectors specialize in it, pretty sure they know what they’re doing.

As a modder, I detest plastic reflectors. If I know up front that a light has a plastic reflector I choose not to buy it.

In case anyone missed it, I’ll probably repost this every now and then.

I have some news on emitter swaps.

I talked to Richard at Mountain Electronics (RMM on these forums and a sponsor here) and told him there might be more than a few guys with GT’S interested in swapping to a cooler tint. He says that if you send in your stock mcpcb to him and buy one of his new XHP35-HI emitters, he will reflow it for free! He has 2 choices right now, 5,000k and 5700k tint. They are both the same D4 brightness bin as the stock GT 4000k emitter.

The cost of both are under $8, plus the shipping cost there and back. I’m in Texas and shipping a small package from him is usually $2 to $3. So I would estimate the entire cost at under $15.

From his store:

Here is the link to the 5000k.

Here is the link to the 5700k.

If your outside of the USA, then I’m not sure what shipping would be or if he even does international shipping. You’d have to contact him for details.

Sirking strikes again! Lol

For best results, tens to hundreds of Al layers are needed. As the last layer of aluminum, SiO2 is used. It’s better than silver.

Oh great, how relevant. Benefits of cucumber in a giant throw forum built flashlight thread.

Bloody spam.

Mmmmmmmmmmm cucumber & spam , arrrrrgghhh

Maybe the cuc makes a handle? Get lost when your cells die you have snack food?

A snack handle - this is a great idea. Would lumintop be open to developing this? If anyone has a vegetable cnc machine we can develop a prototype on…

Don’t quote the link for him!

I know I know, I shouldn’t have done that. But have you seen the benefits of cucumber in a flashlight

I always wonder about the shapes some plastic things have.
Why the shape of a cucumber?
Where they left with some free plastic molds that they used and turned into a flashlight?
Or did someone seriously say “Yes thats it we’ll put a flashlight into the shape of a cucumber”
“you know what throw on a life hammer”
“Roight jobs done well done lads”

edit: looks like a handcrank vibrator

hmm cucumber light. First active cooling flashlight?

I posted a link to this in the comments under the BLF GT unboxing video by VOB as well.

does any one in the UK know any modders dealers that could do the same job of altering the coolness… dont yet have the GT but I much prefer a bluer look
