Just FYI, but cyan is not blue, although between most cameras’ poor white balance settings and possibly your computer/phone monitor’s color profile miscalibration, it may appear blueish in the photos.

> flickering

Besides making sure everything that should be tight is tight and all the threads are clean, consider putting a dab of conductive gel on the theads and on the tip and base of the battery.

Sometimes the springs may be making intermittent contact if the metal was cut at an angle, so make sure that contact is smooth and meets the battery at a broad flat position, not at a knife edge or pinpoint.

Cyan is halfway between green and blue on the color wheel. It’s primarily seen as a blue family and is a key ink cartridge in many printers. It is a mix of half green and half blue, but that makes it 75% blue as green itself is a blend of blue and yellow. Wink

Thank you DB Custom.

 

Yes, i will have an eye to look for ToyKeepers posts, also have to search this forum to learn more.

Have been here many times before, ended up with an account to make questions possible for me.

Very fast response i must say, that response was mucho needed to awoid mistakes with my order.

 

To be, continued.

Nothing has changed in the way that I press the button, but I will follow the suggestions and report back. Thanks.

EDIT:

That was easier than expected – everything working nicely now, and I can no longer reproduce the flickering. Thanks for the advice – it really is a fantastic light, and I couldn’t wish for more (I’ve got the XPL-Hi version in NW).

These numbers look seriously good, especially compared to XP-L HI (which I considered the best so far).

How about adding Osram KW CSLPM1.TG option? Looks like a direct drop-in and should really shine in this host….Vinh claims 4800 lm and 110 kcd.

Yes, we can offer that, please place the order on the site without choosing the LED & tint, then leave us a note about 3000K SST-20, customs order may take one week to ship.

Hank, how about a dedomed SST20 version for even more throw? Would that be feasible?

I don’t know SST-20?

How do they compare to other emitters?
For example to Nichia 219CT?

What will you choose:
Neutral White – Nichia 219CT 90CRI, 5000K
Neutral White – SST20 4000K 95CRI
or any other?

Thank you

Thanks Hank! That’s awesome! I’m going to place an order! I’ve been asking for someone to make some 3000k, thanks for this!

Gregor, the CRI on the SST20 4000k is beatifil. It rivals the best 219b R9080, and runs cooler . It should have a wide hotspot too. Just a wonderful emitter. otherwise get an XPL-HI if you want throw…Hanks’s 3A tint is killer good and clean! I should say XPl-HI my favorite in this torch currently all around…the kcd of the SST20 is also impressive; can’t wait to see the comparisons from out in the wild come in!

Great to see more emitter options being added! Will need to look into the SSTs.

I was previously thinking about getting an XPL-HI version before the HD and SST options came out. Now I’m not so sure!

Anyone know if it’s possible to order a mixed-tint D4S directly from Hank? i.e. 2 x XP-L HI 3D and 2 x XP-L HI 5D?

Based on what Hank posted above, the SST20 (non CRI) actually has more throw than XP-L HI.

Yet the XP-L HI carries a $15 price premium.

That makes sense. The emitter of the SST-20 is smaller than the XP-L emitter => more throw

Also, the SST-20 costs around 0,60€ in quantities of 1000 while an XP-L Hi is around 2,50€ in quantities of 1000.
That alone is a difference in material costs. But please don’t ask me why the difference is 4,50€ per emitter.

I recall some of the more knowledgeable folks hereabouts mentioning mixing several different LEDs to get better color rendering.
If y’all can specify a good combination of emitters, would it be interesting to ask for that configuration?

Those sound awesome.

I’d especially like to see what the 5000K one looks like. I’ve been wondering about SST20 5000K for a while.

People may take it for granted that Emisar lights come with good emitter choices, but compared to almost every other brand, it’s really special and unusual. Take Olight for example… almost everything is cool white, and one of their recent lights only comes in 7500K. Facepalm It’s kind of amazing that Emisar has so many choices.

FWIW, that probably translates to about 82 kcd.

Vinh’s lux meter seems to use a different scale than most people use. The correction factor seems to be about 0.75 or so, if you want to compare the numbers against other people’s. For example, the D1S (stock with no mods) is listed as 130 kcd on Intl-Outdoor or 170 kcd in Vinh’s shop. 0.76 correction factor. Every other light I’ve checked (or measured) also follows a similar pattern with a factor pretty close to that.

LMAO Literally what I was thinking when I read what Hank said and continued to read on lol…. Had been debating on getting an XP-L HD variation but now the SST-20 has been thrown in the mix.

Anyone give any details about how the beam of the SST-20 will be?
