FREEME ✌ ASTROLUX FT03S SFH55 9300lm & FT03 SFT40 2200lm 1300m NarsilM v1.3 USB-C - ALIVE

[Old_Davo]

Late to the party as usual, but would love a coupon code if possible. Thanks Freeme.

P.S. Especially since the bum has dropped out of our AUD.

Is it possible to convince Banggood to release a version of the FT03, with a properly de-domed(not becoming greenish) NW SST-40 LED??

Is there an interest in such version?

Banggood or Mateminco have no way to dedome it. You might talk to someone like Skylumen about that. He does it by hand and is quite good.

Edit, he actually offers it with a xpl-hi 5000K and a White2 6500K. Of course price is higher.

and why cant they dedome it? not like its rocket science…

It’s like asking Ford to hand stitch their seat covers. The workers don’t have the knowledge or skill, it’s way too time consuming and the success rate will be bad. All three things cost money which means the profit margin is gone. Long gone.

Thanks for the code Freeme.
Bought!

You can always try it yourself now that they are selling replacement leds.

I’m not even sure how people are dedoming the SST-40. Are they soaking it in a chemical and then carefully pealing it up? (Too many leds and so many different methods. I can’t keep track of which method works for which led.)

@BlueSwordM

… to reduce costs and to boost reliability, they switched, rather recently, to gold plated copper bond wires, which enabled lower temps, lower costs, and most importantly for us, higher driving power.

Thanks so much! We have so many truly useful people on BLF! Glad we do; otherwise people would just have useless me to tell them what they already know .

@bhstinger

Just came across the FT03 MCPCB w/ SST-40 on BG now.

Thanks! Maybe they’ll add the XHP50.2 version, too.

I just made a post a few days ago mentioning that I didn’t know of a way to get a replacement 5000K SST40 and then Banggood starts carrying the full MCPCB with all 3 tints. Nice.

@BlueSwordM

So guys, I may have found the answer.

I asked Luminus directly by calling them from my new job(lighting manufacturer), and from what I understand, Luminus changed the manufacturing process at some point.

Basically, the earlier SST-40s were using pure gold wires, as it was easy to manufacture into very tiny bond wires, so no new equipment/supplier was needed.

However, to reduce costs and to boost reliability, they switched, rather recently, to gold plated copper bond wires, which enabled lower temps, lower costs, and most importantly for us, higher driving power.

Wow, great job you have, you have your hobby as work And great inside information.

But one thing i don’t understand, isn’t gold one of the best current conductors?
So the production change does not make any sense to me (yet)

Your wondering how switching to gold plated copper wire equals lower temperatures thus allowing higher driving power?

They might have changed more than just the wire composition. They may have also slightly increased the wire diameter (which might have cost too much using pure gold). It would be interesting to find out.

[Yokiamy]

Exactly Jason, there should be more parameters that changed the performance

[kuoh]

I believe pure copper is the better conductor, but gold is more resistant to oxidation and corrosion, which is why gold is preferred in electronic circuitry where long term reliability is needed.

[BlueSwordM]

Well, pure copper has higher conductivity than gold, so it makes sense why they would do it.

JasonWW may have a point here too: they may have been able to up conductivity slightly by making the wire slightly larger just by the fact that they must be using the same diameter copper wire as the original gold ones, but with gold plating, it would make them slightly thicker overall.

[A_M_K]

Thanks for the great inside information, BlueSwordM! Very useful discussion, guys!

Will we be able to identify the new LED version??

[JasonWW]

@A_M_K

Will we be able to identify the new LED version??

Probably not. I’d say that any SST-40 bought in the last 6 months is probably the newer one.

It came out in early to mid 2017 and one was tested in early 2018, it was the early design that burnt at 9.5A.

All the ones in this light seem to be the newer, tougher version.

Maybe anything bought in the last 3 months, just to be safe, should be the new version. I would imagine the old versions are long gone by now.

Maybe someone can post some close up pics of the current version. We already have close ups of the older version. It’s possible we might spot some small difference, maybe around the wires or their connection.

This is more a FT03 thread than a SST40 thread. There’s probably a lot more info on a dedicated sst40 thread.

[BlueSwordM]

@A_M_K, I don’t really know.

[KawiBoy1428]

Wonder if they shortened the bond wires? The old 7500-6500k SST-40’s have long bond wires and break when the dome pops up off the pad, when chemically de-domed, compared to Cree LED’s short and tighter, that people could hot de-dome and flick the dome right off the pad?

The LED’s I de-domed and the Kaidomain de-domed SST-40’s I purchased still have the same bond wire length.

Kaidomain quit selling the de-domed SST-40 for awhile because of the failures, I can say I personally feel for them….

I got Lucky the last 5 I did 3 de-domed nicely… the other 2 will not give up the dome and are still stuck to the pad?

Freeme, would love the code for the $29.99 GB price if still available?

Group Buy Price: $29.99!!!

Which one is better, this SST40 version or the XHP 50.2 version from BG?
