WHAT STANDS OUT

Tunable white, dim-to-warm, and dimming in one: Switch between tunable white, dim-to-warm, or standard dimming from a single controller.
RF, app, and voice control together: Control via RF remote, SmartAir app, or voice assistants like Alexa, HomeKit, and Google Assistant.
High-performance dimming: 0.1–100% dimming range with 2400 Hz PWM and a logarithmic curve for smooth, flicker-free fades.

PRODUCT DETAILS:

The SleekTone CV, 12–24V DC RF / Smart LED Controller, Tunable White is a constant-voltage controller designed for tunable white LED strip systems that need flexible control options. It combines RF control, app control, and voice control in a compact module that fits easily into tight spaces near power supplies or junction points.

Unlike basic dimmers, SleekTone supports three control modes—Tunable White, Dim-To-Warm, and standard dimming—so the same controller can handle everything from cool-to-warm office lighting to cozy residential dim-to-warm scenes. Using high-efficiency electronics (up to 98% efficiency) and 2400 Hz PWM, it delivers smooth, low-flicker performance from 0.1–100% all the way down to true “dim-to-off.”

The controller communicates via RF, SmartAir app, and voice platforms, allowing it to act as a stand-alone dimmer or tie into a broader smart-lighting ecosystem. Multiple SleekTones can be deployed together as a scalable system to control several tunable white zones or fixture types from the same app and voice assistants. With an IP23 rating, UL Listed Class 2 compliance, and a 2-year HitLights warranty, it is engineered for professional-grade indoor projects.

FREQUENTLY ASKED QUESTIONS:

Q: What does the SleekTone CV Tunable White controller do?
A: SleekTone CV is a tunable white constant-voltage LED controller that supports tunable white, dim-to-warm, and standard dimming for 12–24V DC LED lighting. It allows precise control of color temperature and brightness from RF, app, or voice control in one compact unit.

Q: What control modes are available?
A: The controller offers three control options: Tunable White, where color temperature is adjustable; Dim-To-Warm, which warms the color as the light dims; and Dimming, which adjusts brightness only. These modes make it suitable for task lighting, ambiance, and residential dim-to-warm applications.

Q: How is SleekTone controlled (RF, app, voice)?
A: SleekTone can be controlled over RF, via the SmartAir app, and through voice control when integrated with platforms such as Alexa, HomeKit, or Google Assistant. This allows it to operate as a stand-alone RF controller or as part of a larger smart-home lighting system.

Q: What voltage and power range does it support?
A: The controller is rated for 12–24V DC constant-voltage systems and designed for Class 2 applications. The maximum rated output current is 4A at 24V and 5A at 12V, so designers should size the connected LED load accordingly.

Q: How smooth is the dimming performance?
A: SleekTone uses PWM dimming at 2400 Hz with a logarithmic dimming curve, providing 0.1–100% dimming and dim-to-off capability. The high PWM frequency and curve shape help deliver smooth, low-flicker transitions that feel natural to the eye.

Q: Can this controller be used outdoors?
A: No. The SleekTone CV controller is rated IP23, which limits it to indoor applications where it is protected from direct water exposure. For any installation near moisture, it should be placed in a suitable enclosure and used according to its rating.

Q: Is SleekTone CV scalable for multi-zone projects?
A: Yes. The controller is described as scalable, meaning one unit can operate independently or multiple SleekTone controllers can be combined to control several lights and configurations as part of a coordinated system managed through the SmartAir app and integrated voice platforms.

Useless

These will not secure the wire. Even slight pressure will pull the wire loose. Basically useless

Great Connectors!

These connectors are very well made. The screw mechanism also feels solid when you attach the wires or the light strips.

The screw driver is a little on the cheap side, but since that is not part of the connectors I am still rating the connector 5 stars; I just use my own screwdriver.

The thing I cannot figure out is what the little adhesive stickers are for. I THOUGHT they were to attach the connector, but the stickers only have adhesive on one side, that is, they are not double sided adhesive. See photo.
If you peel the sticker that says "3M" off it is sticky on one side. Once you peel the "3M" sticker off one side underneath there is a white slick paper (no adhesive). You flip that over and the other side is brown and say "3M". You peel that off it is also sticky on one side and you are left with the OTHER side of the white slick paper (no adhesive on this side either). So what you have is a total of three pieces once you have finished peeling everything off. Two pieces that say "3M" and are sticky on side, and one piece that is white and slick paper with no sticky on either side.

None of these items are double sided adhesive, so if someone can tell me what they are for I would appreciate it.

Great experience love the product.
