The more I think about a relevant host for optisolis the more I am zeroing in to meteor m43. A good thing about this host is that you can remove some or all optics and get an optimal beam profile - from mule to spot with everything in between. And 12 leds @1amp each would provide enough light for almost anything
I havent tried that, but the mcpcb in an m43 is designed in a way that leds sit between long stretches of copper which allows for some flexibility in placement AND perhaps adding many more leds in addition to the 12
The cool Optisolis leds use a special 420nm led under the phosfor to prevent a dip in the cyan region of the spectrum, this gives them that extra bit of colour rendering. The warmer Optisolis use a conventional 450nm led because the blue/cyan part of the spectrum plays less of a role and going with the 420nm led does not help much. Therefore it does not stand out much compared to the very high CRI version of the E21A.
So, with anything lower than 3000K, E21A is a better option. Better invest in longer regulated runtime. To the naked eyes its extremely hard to see any difference between 3000K and 2700K Optisolis vs 3000K and 2700K (mixed) E21A. From Maukka’s test graphs there’s indeed a substantial higher CRI in color samples. They come from different phosphors mix I guess. As Djozz observed a year ago, Optisolis is the first Nichia with green phosphors, other than obviously, single color green E21A. This green phosphor can be excited by normal 450nm LED too.
I think its great. All the added beamshots and tint comparisons make it alot easier to select preferred LED both for his products and any custom builds you chose to do on your own.
I have a few lights with e21a at this point with 4000k and 4500k and they are by far the best tinted and colour rendering lights I own!
Those are the pictures I promised from my earlier post. This is BLF, people value research, data, and test results. unlike the other forum out there.
Do you prefer I don’t share any information instead? I think I have a problem being an enthusiast and a seller at the same time. Can’t decide which one should I be.
Yes and no. I really like having the data to evaluate. However, it’s also possible to get the audiophile disease where you get lost in evaluating, and forget the real goal is to use and enjoy the product (it’s only a small percentage of audiophiles, of course, but they’re the ones who get noticed).
I’m currently thinking what I should do personally is just order each of the different emitters that potentially interests me on MCPCB’s, try them out on my work bench, and decide from that what my dream light is.
