Fireflies PL47 Flashlight

Thanks, Pavlo. I forgot who made the video, which made it hard to find. With the video URL though, I found the original post about it. ZozzV6 contributed the tutorial.

I just bought two PL47. This is the 6th Fireflies flashlight I bought. Fireflies are you planning to add more color options for the Aux light? People might buy more just to get the different color combination to put on their desk or display shelf. The Aux lights look really nice.

I’d love to pick up another one of these lights with a black body and orange aux LEDs :money_mouth_face:

I would really wish that FireFlies start to manufacture flashlights with threaded retaining rings for the lens and e-switch.

Solarforce was manufaturing their P60 hosts with a threaded retaining ring for the lens and it was years ago, sure it is more cost effective but this kind of design gives a better feeling.

Their L2-B1 stainless steel retaining ring was flush with the edge of the head and I remember to have asked them to make a retaining ring that could protect the edge of the front of the head and they made the L2-B6 retaining ring a few months later.

The PL47 gives the impression to be a bit expensive considering the press-fitted design.

Which version would be best for bright flood?

I would also consider a request for adding Samsung LH351B/C/D for FireFlies flashlights.

While LH351B/C emitters are less efficient (and powerful) than LH351D, they might be good when better throw is needed - but in 90+ CRI, LH351D is offererd with the most options, including a 6000K CW, which I would strongly welcome in moderately floody flashlights. LH351D have possibly more output, while being not much worse than SST-20WxH regarding R9 values (~65 vs. 80+).

If I think about Luminus SST-20WxH (95CRI), I would pick a ‘FA1’ or ‘FA2’ tinted variant for the best neutral white, but I would also welcome a ‘GDx’ (x could be any of 1, 2, 3, 4) tinted one for a mildly warm white around (or a little bit below) 3500K.

XPL HI …pick your flavor of host and kelvin

Would that be a Halloween special edition?

I would probably pick one up. Any coupons available?

Of course, and lose the glue.

Many manufacturers tantalise us with threaded rings that have an odd number of indentations, so a special tool is required, or lots of ingenuity.

Even then they are sometimes a tease, and really a press-fit. Or glued up. Or threaded backwards.

Instead of simply using some circlip pliers, or the thing that takes the back off a watch with two prongs.

Even number of indents please, no glue, threaded in the usual direction.

Same applies to driver retaining rings.

Mine will be attached to a helmet(for caving) so 5000lumens will not be an issue…

Just discovered this nifty little (big?) light! My wife’s birthday is next week, she uses an outdated Crelant headlamp every day, so she will soon be trying out the PL47 with SST-20 emitters in NW. :smiley:

Thanks for a job well done!

Will there be rattle using 18650?

Hey High CRI folks, can anyone show me what the beam tint looks like from the 95 CRI SST-20? I bought this one and got to thinking about the 4000K, how warm does that appear? Anyone know? Haven’t heard from Fireflies on my order, assume they are out for the weekend…

They said nov 13th…

Didn’t see any mention of that, went to their website and ordered it. No indication it wasn’t ready or in stock.

No mention of release date in the OP, zip about Nov 13 in this thread. Where was this said?

The Fireflies website clearly states this light is in stock, just left the site. Oh well, it is what it is I guess…

When I compare the SST20 4000K to my Viltrox L116T light panel, it looks pretty close to the panel’s 3800K setting. But I don’t know how accurate the panel is. It seems to match up with my other lights pretty close to the expected values.

The main reason I’m not sure about color temperatures is because maukka’s measurements are usually about 500K warmer than mine. For example, he measured the ROT66-219B at 4200K, while I measured mine at 4700K. Something there doesn’t add up, and I haven’t figured out what yet.

Anyway, I’m a bad person to ask about warm CCTs. I think everything around 4000K and warmer looks unpleasantly yellow, including the SST20 95CRI 4000K emitters. But a lot of people seem to really like it.

How reliable is a DSLR for accurately measuring White Balance?
If you take a picture of the beam on a pure white wall in complete darkness, and then upload the the raw image into lightroom, do you think the White Balance on auto would be pretty accurate?

I will test this method when I receive my 219b PL47.
