The switch is part of the light
A 0-10V LED strip is not a bulb. It needs a control signal rather than power simply interrupted, and putting a hardware-store dimmer on one gets you flicker, buzz, or a strip that drops out entirely below half. The Spectrum 442 is made for the job: a slide dimmer designed specifically for LED fixtures running 0-10V power supplies and 0-10V fluorescent ballasts.
What it drives
It is the control for Bathology’s Spectrum 440D and 441D lighting systems and works with the Spectrum 240 and 241 steam LED lights. If you are running Brilliance 360 dotless strips, this is the family they belong to.

Two things people miss
The cover plate is not included, and it takes a Decora-style plate rather than a toggle plate. And no separate power pack is needed for switching, which is worth knowing before an electrician quotes you for one.
Where it goes
Outside the hot room. This is a standard wall device and it belongs on the dry side of the door with the rest of your controls, not inside the sauna.
Why we sell the controller separately
Because most people buying strips already have a switch location decided and half of them need the 3-way. Selling the light and the control as one fixed bundle would make one of those two groups pay for something they cannot use.
