Luminus SST-40, a N4 BA bin tested

Could be, I’m waiting for the dedome experts to do a clean dedome, should be possible. In my led there are bits of silicone still present on the die.

Luminous efficacy would be nice, but can be derived from the chart if you extract the numbers. This parameter for flashlight use is a bit less relevant than you may expect though, many types of regulated drivers burn off ‘overvoltage’ which makes the efficiency of the flashlight a lot less related to the efficiency of the led.

Yes, I know what can be derived. It’s just that reading data from the chart only increases the error.

I am always peaking on your reviews and hoping for… Well you know what…

But very valuable review to anyone on this planet.

And yes imho hot gas(or other suitable hot solvent - i use other solvent) is far superior and easier than hot de dome. I know that you are scientist but I can teach you that if you want :slight_smile:

Thanks for your efforts!

What is the diameter of the large opening of that reflector?

The D80 reflector opening is 34mm

Based on djozz’s measurements here, the D80 should do about 25% higher in candela than the X6 reflector, which is consistent with the ratio of their areas. A dedomed XPL V6 1A will do around 95Kcd in an X6, with the stock X6 AR lens. So it looks like the SST-40 falls short of the current best emitter for good output and throw (IMO), even with the higher current of the SST-40. But we will await additional results.

Oh yes, the reflector project , it is still an ongoing project but the results are more exciting than doing the measurements so it has stalled :innocent:
It is still a plan to test many more reflectors.

SST-10-UV 365nm

The great thing about your method is you have the data you gathered from the others to compare these too.

Very interesting, thanks :+1:

I need to figure out what light to put this in. Hopefully KD stocks better tints and bins soon. Thanks for another very informative test.

Interesting that this sst-40 is the same size and thermal resistance as an xml2 but the maximum rated current is 5 amp instead of 3.

Nice test thank you for your effort :beer:

I think it’s great emitter, I just hope it will be available in more neutral tints. I found a seller on Aliexpress selling them for $1.69 I have ordered some so I can practice my de-doming skills.

Thanks for the testing :slight_smile:

If anyone has seen the N5 or P2 bin listed, I’m keen to grab a few.

Thanks for the test. I like what i see!!! So the Q8 with VTC6, mod ledboard and SST-40 P2 Bin will draw something about ~30A. Maybe even more. :smiling_imp:
The low Vf is really nice! The low CRI is not so. But i am curious how much output the Q8 would get with the P2 Bin SST-40? 8000+lumen?

Aside from the low CRI how does the light look? Is the beam ringy with color artifacts like the newer crew emitters, or is it fairly consistent?

I’m sorry to say I don’t know, I had 2 emitters, one died in the test, the second was dedomed. The dedomed tint is towards a bit yellow, but a good tint, a quite uniform hotspot with a very thin blue-ish edge around it. Nothing of the problems of the new Crees.
One thing I seem to notice is that the led has a large tint shift going from low to high current, the good tint only happens at highest modes when the BLF driver mainly uses the FET.

Wow, impressive graph!
7.5 Amperes seems to be sweet for this thing, at only 3.6 Volts. !
That’s 27 Watts, but ‘just’ a bit under 2300 Lumen.
2000 lumen at around 20.5 Watts though.

Happy to hear the tint looks decent. I have one coming with my next order, got it just to play with, but I’m quickly thinking of uses.

Thanks for the most excellent analysis. :+1:
