Is there a ETA on 519a LT1s and how many will be produced in the first run?

@Barry0892, will it be possible to buy the LT1s Pro driver separately, and retrofit a regular LT1s?

Need to wait for the second batch to see if there are more drivers.

Sign me up for the interested list for a 519A/anduril2 version.

I mix red and white a lot. 5700k 519A + red SST20. Lets me add a tiny bit of the red to make the light slightly warmer (I prefer cool CCT overall, but there are moments warmer is useful). Having it as a default switching-only might make sense but I’d definitely be configuring/hacking it to ramp as well.

It would be a lot of work, but might be helpful for these situations: Make FSM fully n-channel compatible.

What I mean: Each of the n channels is by default fully independent from other channels. When the UI implementation wants channel 0 to be 50% and channel 1 to be 10%, all it needs to do would be something like:

set_level(channel_0, 75);
set_level(channel_1, 15);

This would allow the UI implementation to have full flexibility of how the channels are used. Additionally implement a mixer that can be configured to create virtual channels that can be controlled together. I’m thinking about various modes like a simple linked mode where both channels get the same value or a tintmix mode that allows to set a ratio between both channels.

// I hate "OOP" in C...
Channel channel_0 = MAKE_CHANNEL(...);  // warm white
Channel channel_1 = MAKE_CHANNEL(...);  // cool white
Channel channel_2 = MAKE_CHANNEL(...);  // red
Channel mixed_channel = MAKE_CHANNEL_TINTMIX(channel_0, channel_1);
...
set_level(mixed_channel, 42);         // set total brightness for both channels
set_channel_mix(mixed_channel, 128);  // set mix to 50%
set_level(channel_2, 50);             // add some red
