Light controller for a BML MC series that dims to 0%?

Hello All,

I am wondering if any of you have built a DIY light controller for the new MC series from buildmyled. The MC series of lights have 3 channels which dim to 0% (the other lights only go down to 10%) so I am thinking they are using a new LED driver compared to the other models.

I am curious how you approached building your light controller and I'd like to pick your brain.

Thanks,
YT

I can't be of help, but that's good to know. I was debating picking them up to use with my Apex controller. If I can't dim to 0 I have no reason to stop using the regular series of their lights I have.

Thought the Apex could always "dim to zero" (actually shuts the plug off for the last 10%) if I remember correctly..

The orig BML was dim to 10% shut off w/ a timer for the last "bit"

Their use of "industry standard dimming protocols" is driving me crazy...

The Apex can definitely dim to zero, it's the BML's that don't. That's why I wanted the MC's so I could potentially dim to zero.

Really wish I tried making my own or sourcing from a place that can make them custom with better drivers....

What about their statement of using industry standard dimming protocols bothers you?

Besides the fact that there is no "standard", making the aforementioned company's statement meaningless, perhaps?

I view "industry standard" as a vague term meaning they aren't doing anything special that deviates from common practice and it seems like there are a lot of 0-10v dimming solutions out there so I'll give them a pass on that phrase.

you'll appreciate this one:

California Title 24

Significant changes to certification, lighting alteration, and
lighting controls requirements

Multi-level
lighting control requirements no longer allow checkerboard/ alternate row switching; each
luminaire must comply.

Multi-level lighting requirements vary by technology

LED luminaires, LED
source systems, GU
-
24 sockets rated
for LED require continuous
dimming from 10%-100%


see pg 40..

not to mention catering to the Apex/reef crowd

PWM dimming to zero is arguably the best method for our hobby..and honestly, the simplest.
