What this remote actually does
The C3 is a handheld RF remote dedicated to CCT adjustable white lighting. Instead of one channel of brightness, it gives you two things at once: dimming level and colour temperature blending between the warm and cool channels of your tunable white LED strip or puck kit. Because the dimming happens at the receiver, you do not need a dimmable power supply or a dimmer on the wall — a standard driver plus a compatible controller is enough. That makes it a favourite fix for finished rooms where opening a wall to pull a new switch leg simply isn't on the table.
Radio frequency, not infrared
Infrared remotes need a clear shot at a receiver eye; this one doesn't. The C3 transmits at 2.4GHz with a stated control distance of 30m, and the signal passes through walls, floors, cabinet doors and furniture. Hide the controller inside a millwork cabinet, above a dropped ceiling or behind a TV — it still answers. The remote is powered by 2 x AAA batteries for a 3V supply, so there is no charging cradle, no wiring and nothing to install. Keep it on the counter, in a drawer, or stick it near the door where the old switch used to be.
One zone, unlimited receivers
The C3 controls a single zone, and that zone can hold as many paired controllers as your project needs. Run three separate power supplies along a long kitchen island, a pantry and a bar back, pair each receiver to the same zone, and one press dims or tunes all of them together. This is the clean way to light a large room evenly without splitting it into groups you never actually use separately. If you later want several zones on one wall panel, keep the C3 for the room it serves best and let it stay dead simple.

Applications and documentation
Think under-cabinet and toe-kick lighting in a kitchen, a tunable white cove in a basement family room, reading light over a bed, vanity and mirror lighting in a bathroom renovation, display shelving in a boutique, or a home office where cool light helps during the workday and warm light takes over in the evening. It suits both residential and commercial projects, and it's an easy upgrade for a client who already owns adjustable white LED strip lighting but has been stuck with a single fixed setting. The technical PDF for the 1 ZONE RF REMOTE CCT ADJUSTABLE WHITE (C3) is available in the Documentation tab — check the receiver list there before ordering so your remote and your controller speak the same language.
