Magnetic with filament pathways.
Trying to figure out how to make the patent drawings. :sunglasses:
This. IMO the EDC fabric is about to be resown. Essentially small quads ala DS4, S43, etc., with Osram Flat Whites. Heat management issues subsequently for the most part resolved. Carclo type setups specifically tuned to specific LEDs. Drivers, firmware, et al to adjust designs accordingly. I see all this coming. Osram sees it. Maybe even a small cottage all U.S. made company will crop up out of it at some point depending on how far this tariff spiff goes.
PS. I’d go to work sweeping floors at a new U.S. flash company if they gave me a 50% discount. I figure considering what I’ve spent in this “hobby” I’d be ahead even making minimum wage. :laughing:
Some crazy high powered blue module, no doubt. Got a link?
A crazy obsessive genius with no funds, maybe called Emmet, will put together, in their shed, an arrangement of salvaged laser modules from scrap DVD and Blue Ray burners.
Focussed onto a single Dilithium crystal, to charge up a flux capacitor, using inertial fusion confinement.
Which can then be bounced off the moon, or just a fake moon.
Maybe we could all have our own individual “fake moons” precisely directed, using CubeSat technology.
But that would never be allowed by big business, and the Lizard people.
Nah, the Lizard People are cool with it. I asked.
2019: Tom Tom will design, build, produce & release the perfect driver and be revealed as one of the Lizard People 
I really hope so!
Nitecore is doing great with some of there ‘different than cylindrical’ designs.
I would really like to see some more aluminium cast designs. Or even plastic injection molded lights.
Also had to buy a driver, safety goggles, etc and it all added up.
Maybe in 2019 I’ll finally get the 21700s I ordered… :weary:
CRX will find a way to make threaded parts. 
It’s a journey
My hopes / predictions for 2019:
- 100k lumen production run (non-custom) flashlight.
- FW3A gets released and is in my hands
- More LEP flashlights and reduced price on LEP.
- LEP zoomie flashlight
- Emisar D5: Basically an Emisar D4 with (1) knurled battery tube, (2) recessed button, (3) unibody construction (head and tube are one piece for improved thermal management), and (4) battery tube sized to fit a 21700 cell.
Do-it-yourself CRI metrology.
That’s called looking with your own eyes and deciding what seems good.
Instead of obsessing over numbers, and graphs, and placing other vocal, maybe a little bit self-obsessed, peoples opinions above your own.
Trust your own judgement.
The technical analyses and reports are very useful, but it all gets messed up for ordinary people who just want to to buy something ordinary, and use it. Instead of having to listen to reports of how dreadful they all are (seems to be a theme), and e.g. an emitter swap is essential, or even that some colour correcting filter must also be applied before it can be tolerated by any “right thinking” person. And that the “BBL” matters not in the least (hint, learn about how eyes respond to colours and intensity, and no, they are not tuned to some hypothetical Plankian emitter).
I’d like to see more powerful built-in processors, with either WiFi or Bluetooth connectivity to smartphones/computers for full control of adjustments and settings and programming, or even remote operation. Mechanized zoom would be cool as well; I’ve seen them in HID torches. How about solderless MCPCBs and driver boards using ribbon strip conductors for low profile?
Coincidentally for warmer LEDs it looks the best when it’s high CRI with plenty or deep red and a hue towards red (under BBL)
Of course, but the numbers can tell you what to expect from an LED or it can confirm what you perceived.
You don’t have to care if you don’t care.
Well, not everyone is a CRI baby, nor should they be.
You’re right about how the visual system responds, but it’s not the full story.
It doesn’t mean that you won’t notice the traits of a certain LED.
For example, skin tones are very telling regarding CRI and the amount of red.
And often you leave a place where there is high quality light (tungsten bulbs, candles, kerosene lights) before you use your flashlight, and then you notice what your LED does.
This also translates to numbers you get by testing.
Pleasing LEDs have he numbers to prove it, as do unpleasant LEDs.
Important? Maybe not, but to some important enough to care about it.
Plus, it’s a welcome development comparing to the XR-E days.
And it’s a hobby where you can choose to pursue perfect lighting.
When you can’t properly convey the tint or colour temperature of a flashlight through a picture (because cameras and monitors and blablabla) measurements are needed to compare and evaluate.
The other option is for each individual to literally buy every LED that exists and compare them in person.
To save time and money, measurement standards were developed.
Welcome to the 21st century where we make educated decisions instead of guesswork.
Nope, that’s just part of trying to put things into neat little boxes, where a single number, or parameter, can be used as a marketing tool, or bludgeon, to steer the masses in the desired direction. Or utterly mis-lead. Or create a job for life on a standardisation committee and reap the rewards.
Some manufacturers really are trying. Others don’t have a clue. For example, the “eco-friendly” LED powered streetlamps that have been mandated here (CO2 emissions reduction grants incentivising this, together with jobs for the boys tearing down the old and replacing with the new) to replace the previous equally efficient high pressure sodium orange jobs are an example.
The dismal, dreary output of the LEDs is instantly obvious, as is the superiority of the old high pressure sodium lamps, in real use. And for old eyes. And in UK weather (generally wet, misty, foggy) And at least astronomers could filter out the sodium line from their imaging with a straightforward filter.
Start here for some self education, it is a complex subject, and above all, trust your own eyes and judgement.
And try to remember that it is all just a delusion, a trick of the imagination, something learned, maybe then un-learned, particularly when others are determined to put doubt in your mind. And if you were a different animal, or just have a Y chromosome, or descended from a different ethnicity, things probably look completely different. Blue eyes (me) vs. brown, for example.
Bottom line is that LEDs are generally rubbish, they usually don’t match the human eye, its just that some are better than others. Some do try their best, but it is an imperfect and not well controlled or understood process. Binning under test is one (expensive) way, but as soon as you start cherry picking the “good ones” you have to accept that the leftovers become less desirable. But still have to be sold to somebody, if the overall process is to be viable. Making them all “perfect” isn’t possible yet, that’s just the way the phosphor gods throw the dice. Then we modders like to burn them up at vastly higher currents, and are surprised to find that things change yet again, and no, they no longer last “20,000 hours”.
A Sun, an incandescent filament bulb, a flame, a mantle, all deliver much nicer light. But don’t have the surface brightness that an LED can make. (Perhaps the Sun does, but I haven’t researched the numbers). At 5778 Kelvin surface temperature, then filtered through our atmosphere, usually half sideways at my latitude, it is hard to tell.
Perhaps a standard candle, made of Spermaceti extracted from the heads of whales, might be more useful ?
Tricky to insert into an integrating sphere though, and might make it sooty.
I’m not sure our current standards are any better, though at least one person is trying and selling his “standard candles” calibrated in arbitrary but hopefully consistent units.
Meanwhile hanging on to my stash of incandescent bulbs (banned), and halogens (also banned). Expecting fire to be banned next, atmospheric oxygen taxed, and farting to become a crime.
I didn’t even know that we had a “Prince of Wales’s corporate leaders group” until I read that article. Heaven help us when he finally gets the reigns, and his feet under the table.
I wonder what the requirements are to become a “corporate leader” and join the POW’s lunch club ?
Meh, people test LEDs and share their results so you and i can get a pretty good idea of how it will be in real life.
BUt i said this already in reaction to you… :person_facepalming:
Yep, CO2 guilt is big business…
Are you sure the Sodium lamps are just as efficient though?
YEs, still a long way to go…
But recent developments are going in the rightdirection, regarding tints and colour rendition and efficiency.
If you have never used a real neutral, high-cri, high-R9, high tm-30-Rf, at-or-below bbl led, you really can’t grasp what is possible. Most people don’t know how good LEDs can actually be these days. They are used to those that “suck”.
