Courui "Even Bigger Head" D01 Projector: 113mm Lens , Luminus SBT-70 @ 13.5Amps *Build Stage*

I say it needs a belt clip :party:

Cool project! :beer:

Very, very interesting project

OMG, I am feeling proud…. Don’t worry I will send you a heatsink even if there is no-one else interested, just to see this beauty! !!!

Haha, great! :slight_smile:

But there’s a fair bit of interest, almost 10 already. I’m sure they’ll continue to come in steadily, quite a lot of people here have this light.

I have the SBT-70 in a Tangsfire ST2010. De-glassed. :slight_smile: Yes, I popped off the glass cover and it is sitting down in there naked. And works better. And the beam, even in the semi-lowly 2010, is gorgeous. Set up like you’re doing, it should be truly a thing of beauty. It IS a bit on the blue/white side though, so try to get the right tint if that’s possible.

I am willing to transfer this SBT-70 over to my Courui on the copper pill. I think that’s an excellent idea actually! I took it out of an SR-90 Intimidator. I put it in an 18350 EDC Cypreus, then a chopped MiniMag, then the ST1010. lol, yeah, it’s been around.

Luminus emitters are power hungry. The SST-90 will pull 16A if you let it, this one does 6.35A on a 26700 King Kong that’s (oops!) down to 3.75V. :slight_smile: (It’s now on the charger.) :smiley: It’s on a RyanSOh copper pill.

In the little copper Cypreus…

Windowed, going into the chopped mini-mag…

Cool to see it “rehoused” so many times without being bothered, also didn’t know you could whip off the “flat dome” window, thanks. I’ll probably leave it on initially and see how it fares, then if I decide to employ some spill capturing it’ll have to come off :slight_smile:

From what I can tell, there’s a ~7000k, a ~5700k and a ~3000k temp/tint range available right? Which one do you have?

I have my eye on the 5700k 90cri variant, seems to be available from mouser fairly locally but I really need to chuck a few more things into the basket to make the shipping costs seem justified.
The one on kaidomain is a good price with free shipping but that’s the 7000k, so a fair bit too cool for my tastes, even for a dedicated thrower.

Cheers

I would think this one is the 7000. Like I said, I modified an Intimidator and was allowed to keep the emitter that had been put in it previously. It’s way too blue for my taste, but somewhat better in it’s “open window” attire. :wink:

I had looked at that 5700 variant and had it in a cart multiple times. Couldn’t ever justify the cost of it without knowing how it would perform. I’ve found the Luminus emitters to gobble up more battery than they give light for. So they’re not very efficient. But look cool as heck in the light and sometimes, that’s enough! :bigsmile:

Edit: I don’t like aspherics for the square die pattern, but I have to agree, this one is the answer to that issue and I can’t wait to see how yours performs!

Edit II: The window is stuck on a metal frame with adhesive tape. More adhesive secures the frame to the substrate. It’s not on any phosphor or bond wires. Ridiculously easy to take off. :wink:

Pah, efficiency is overrated. I burn off more power than this thing uses in my BTU cable! :wink:

Unfortunately I won’t be able to see the emitter too well behind all that glass but the beautiful circular beam profile should be well worth the price of admission. Heck even in a SMO reflector the effect of the circular die is clearly apparent, lovely stuff.

Interesting that removing the window has changed the tint, perhaps you’re seeing a subtle variation on the dedoming tint shift. Of course a lot less pronounced since the window isn’t directly touching the die, but maybe similar principle.

What a great photo. Those SBT’s look like high tech works of art.

Slightly different lens/emitter ratio and focal length between these two lights , but I’ll stay optimistic that I’ll acually be able to see the thing in there when it’s done, would be nice. :slight_smile:

The SBT70 in my TS2010, with a freshly charged King Kong 26700 5000mAh cell, pulls 9.23A.

This is one of the early BLF fet drivers, and it’s sitting on Ryans copper pill, a pretty healthy chunk of copper.

Interesting, would have thought it might pull more DD, but there’s too many variables at play to really know what’s going on in a light.

Has anyone anywhere done any testing on this emitter to see how far it can be pushed? If not I’ll try do a few safe-range tests to see how it responds. Curious to see if the vF stated in the datasheet is accurate.

A Sony C5 18650 allows 10.02A

What bin SBT70 do u guys prefer ?

The 5700K variant would be the one.

Thanks Dale first thing i will try mine on is the 4" double aspheric lens i have :)

All this talk of this gorgeous emitter and I had to look it up at Mouser. They happen to have em in stock in the 5700K version for less than I’ve seen em ever, end of life they say! So I ordered one. The wife will kill me over this stuff some day…

Dale can u send me the link ?

Now, they’re still not what anyone would call cheap. Just cheaper than they were! :wink:
