His 12-group driver is not Biscotti but it’s highly derived from it. Back in the day, ToyKeeper made the Bistro firmware, and then later trimmed it down a little to make Biscotti just for Simon. I don’t know if he’s still using Biscotti on anything but maybe…2-3 years ago he had some issues and then developed his new 12-group, very similar to Biscotti in features.
Dr. Jones, TomE, and ToyKeeper (and others) designed several of the popular firmware programs years ago, many of which are still used today. Probably a lot to wade through, but a forum search for each will tell you as much as you want to know. Richard at Mountain Electronics still offers lots of them and has good quick rundowns of each. Take a look at his drivers and scroll down to where he describes the firmwares offered…several have a separate page that you can click the links to read more about (features and operation, sometimes more). Here’s one that has most of them listed: 26mm FET+7135 Driver - MTN-26DDm - 1S Input Voltage
As for the driver in your light, he says down the page that is has a max of 4.8 amps (4800mA), and he also says the light gives about 1100 lumens with that emitter. Measurements tell the truth but Simon is usually pretty accurate and he lists out-the-front actual lumens rather than paper lumens (those being a theoretical max based on component specs, not accounting for efficiency or losses from resistance, reflectors/optics, lenses, etc).
If you were to browse the data sheet for that emitter, you might expect the driver to only be delivering around 3.5 amps for the stated lumens and with the bin he has chosen to use, but again, all that extra mumbo jumbo reduces actual light output from theoretical. I assume the bare emitter he’s selling separately is the same as what he’s using in the lights (that’s usually the case), and if so then he’s picked one from the available bins that has a bit lower lumen output, but it also has a lower required voltage and a better spot in the tint chart which reduces the green a bit. This is what he usually does, picking one with a good balance of performance and light color, rather than playing the numbers game for max-advertising-lumens.
If you want to browse the data sheet for that emitter, here’s a link. Even if it’s all greek to you, it’s fun to take a look and I know when I first started doing so it actually helped me understand a couple things, and then I started to explore all the other things I had no clue about, and understood more after that. If it produces more unstupid questions, post ’em up. lol
And Simon’s link to the emitter, where in the title description you can see the binning information (model)….which is 6N for “brightness group”, 15 for voltage group, and ebxD46 for chromacity/tint group (pages 4 and 5 on the data sheet): https://www.aliexpress.com/item/4001238336707.html
