Luminus SST-40, a N4 BA bin tested

My other BLF-D80 has its stock XM-L2 dedomed and the same driver, it does 95 kcd. But it is an unknown bin, I can imagine that others have had better results with high binned dedomed XM-L2 and XP-L. Anyone?

Thanks for the test mate. We may see these being used around here very soon. I’ll buy some soon should make a good pocket rocket flooder.

djozz, could you please add a table with individual measurements (preferably with power consumption and efficacy) to the chart?

I could add the numbers but it will suggest an accuracy that is not there. My djozz-lumen was never properly calibrated so it is mostly useful when comparing it with my own measurements of other leds, and that is best visioned in a chart like above.

Thanks for the test djozz. More invaluable info. :slight_smile:

Hmm? I would have though there would be better throw based on the output you have measured. More light that a dedomed xml2 from the same die size would make me think more lux. Maybe the phosphor isn’t as smooth and scatters light a bit more to the sides?

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.
