A 12V dimmable LED driver designed for wet locations, this HitLights 40W IP67 knockout driver provides regulated low-voltage power and smooth wall-switch dimming for single-color 12V LED strip lights.
Built around the EK-Series electronic platform, it accepts 120VAC input and delivers 12V DC output up to 40 watts (3.3 amps) with a high power factor of about 0.95 and efficiency around 90 percent. Internal knockouts let installers keep all line-voltage and low-voltage connections inside the metal housing for a safe, code-friendly installation. The enclosure carries a NEMA 3R rating for dry and damp locations, and an IP67 waterproof rating for outdoor use, making it suitable for decks, patios, landscape and architectural lighting where exposure to moisture is expected.
MLV TRIAC phase dimming supports a 0–100 percent dimming range when paired with compatible wall dimmers from major brands such as Lutron and Leviton. Over-voltage and short-circuit auto-reset protection help protect both the driver and connected LED strips, while Class 2 low-voltage output simplifies compliance with many lighting codes. The unit is assembled in the USA and backed by a six-year warranty.
Unlike basic plug-in adapters or non-dimmable supplies, this EK-Series driver is engineered for phase-cut dimming and outdoor use, giving more stable, flicker-reduced light and better control from the wall switch. It fits professional and advanced DIY projects that need reliable dimming for outdoor coves, under-cabinet runs in damp areas, signage, and other permanent 12V strip lighting where safety listings and weather protection are important.
WHAT'S INCLUDED:
Q: What is this 12V 40W knockout dimmable driver used for?
A: It is an electronic dimmable LED driver that converts 120VAC input to a regulated 12V DC at up to 40 watts for single-color 12V LED strip lights. The driver is intended for permanent low-voltage installations such as outdoor coves, under-cabinet runs, and architectural accent lighting where wall-switch dimming is required.
Q: Who is this waterproof dimmable driver designed for?
A: The driver is aimed at electricians, low-voltage contractors, integrators, and advanced DIY users who install single-color 12V LED strip lighting in wet or outdoor locations. Its Class 2 output, IP67 rating, and knockout housing support projects that must meet code and withstand moisture.
Q: How does this driver work with a wall dimmer switch?
A: The driver connects to 120VAC through a compatible MLV TRIAC wall dimmer and outputs a dimmed 12V DC signal to the LED strip. It supports a 0–100 percent dimming range and is compatible with many Lutron and Leviton dimmer models listed on the manufacturer’s compatibility sheet.
Q: What are the key electrical and environmental specifications?
A: Input is 120VAC (108–132VAC), 50/60 Hz, and output is 12V DC, 40W (3.3A) with a power factor around 0.95 and efficiency near 90 percent. The housing is NEMA 3R for dry and damp locations, carries an IP67 waterproof rating, and is safety-listed as a Class 2 circuit.
Q: Is this driver suitable for outdoor and wet locations?
A: Yes. The enclosure is rated NEMA 3R, and the unit has an IP67 waterproof rating, meaning it can be used in outdoor and wet-location installations when properly mounted and wired. It is commonly used for decks, patios, landscape lighting, and damp under-cabinet areas.
Q: What types of LED strips and dimmers are compatible?
A: The driver is designed for single-color 12V LED strip lights and should not be used directly with RGB or multi-channel strips. It works with many MLV TRIAC wall dimmers from brands such as Lutron and Leviton, as detailed in the compatibility documentation.
