Big Smile . Big Smile

Wasn’t trying to make it sound easy… though it was.

I just did not want to dissamble the head unless I needed to.

More things taken apart, more chance for something to get messed up.

Have not reassembled this one yet, so not sure if I will have to loosen the bezel or not to do it properly. That remains to be seen.

I am thinking go slow & easy……..
………..making sure all is line up properly, it will be NO.

BUT you have done the reassemble Dale…. what says you. Smile

The light is well made Teacher, reassembly with the Bezel still snugged down is painless.

However… I find it more optimum to NOT have the bezel so tight. I also removed some material on the underside of the Delrin centering block, it was cupped underneath and held the reflector a bit too high for my liking (agree with Kawiboy on this). Putting the bezel back on it seems to do well for the definition of the hot spot to not snug it too tightly. [my Delrin block was 2.8mm thick, apart from the centering ring section, and flat across the top both in the block face and across the ring. When I got the base flat the block ended up 2.5mm thick.]

/\/\/\ … Thank you sir…. Thumbs Up … Good info.

Glad you mentioned the Delrin centering block too. I had forgot what KB had said about that.

The reflector is loose and sort of floats in the head, the centering ring aligns it when the head is tightened down. Wink

I think you would be surprised how quickly the modern CNC machine can carve up a big chunk of aluminum. I’m almost positive it’s quicker and cheaper to do it this way as opposed to using a forge and melting down aluminum then making castings which are going to end up not perfectly round for the lathe to grab ahold of.

Recycling the massive left overs is quite easy. It just gets shipped off. The place doing the machining doesn’t have to deal with it.


A lathe can quite easily grab an out-of-round part and make it round. There may be other technical issues with making the reflector as a machined casting though.

In general I agree that hogging these out of solid rod makes more sense at low quantities. I do hope that they’re saving their sharp tools for nice slow finishing passes. Tool wear could certainly explain the bit of variance in the finishes we’ve seen.

Trying really hard not to be that guy, but I paid back in December and my name is not on the paid list. I did get an email from Neil asking for my phone number, but that was close to two weeks ago and I haven't heard anything since. I've been trying to keep up with this massive thread to figure out how the shipping thing is supposed to work, but I can't find anything to inform me where in the process my order is.

You are the same as everybody else. We pay our money and just have to wait. 850 orders went in and 500 have currently shipped. As production rolls along at 150 to 200 lights per week, they are steadily shipping them out.

It is cumbersome to show your pics here. Always wondered why they insist on file hosting…

That makes sense. Can you tell me what FREE site(s) are good to use, if any? I remember searching a few different ones in the past but they all wanted money.

Damn! Been out of the flashlight buying game for a bit and come back to miss this by days!

If there’s any chance I can sneak on to the end of the group buy list (or anyone’s ordered too many!) Please let me know. Dan (London) Cheers…

Picked up a new toy…………..indispensable measuring tool today.

Now that is one awesome tool. I hope you know you are now obligated to test and upload results for every light you own lol.

That means I have to break out all the heavy iron from their storage places. That’s a lot of work. But eventually, it will be done. I’m under the impression that typical XBO/Xenon Short Arc lamps have CRI’s in the 90’s. It would be fun to confirm this.

Seriously though, I would be more than happy to measure lots of light sources for people if they send them to me. Send complete lights, bare LED’s, commercial bulbs, whatever you might want measured. I have programmable current limiting power supplies so I can power up bare sources so to speak. Example: LED’s on stars as long as I can get a reasonable sized contact area or u attach wires to it. I can provide Kelvin and CRI/extended CRI measurements and, although I do not quite understand them yet, info on where the source is in relation to:

CIE1976
CIE1931
XYZ
xyz
u’v’
λp (Peak wavelength)
λd (Dominant wavelength)
Pe (Purity)
PPFD

Maybe a database/repository of sources and their measurements could be kept on the site.

Here is a video of how they might make the reflector, probably using more CNC and less human intervention…

Thats a pretty cool video on making a reflector, but I really dont think most of the reflectors in the lights we use are made like that. If you notice a page back the pic of the GT reflector, p60, c8 and s2, I would say all 4 of those are turned down on a lathe, not rolled out like in the video.

The GT’s reflector is NOT made by spinning.

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:

Quote:
BLF GT LED SWAP

​Don’t like the tint of your BLF GT XHP35 HI?  Send us your MCPCB and we’ll swap it for this one. 

Please ship your BLF GT MCPCB to us and we will swap it, test it, clean it, and send it back to you.

Your entire order will not ship until we receive the LED and get it ready to ship.

Ship to:

Mountain Electronics LLC
8076 S. Box Canyon Rd.
West Jordan, UT 84081

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.

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

I’ll have to see if I get one (I was just outside of the 1500), but I may try an emitter swap on it too. Ill let you know if it goes okay.

Maybe not, but I think they kind of bit off more then they could chew on this group buy. They wanted the first 555 to put a deposit to prove there was interest. I think they were skeptical that they would actually sell 555, not to mention 1500+.
Companies like lumintop are not used to selling to individual people either. They typically only sell wholesale to retailers. Yes, Neil is used to retail selling and shipping, but this is pretty large scale considering all of the steps involved from manufacturing to the end results of getting them shipped
