About 700MOBRK8353503Z One Light Head
What is 700MOBRK8353503Z One Light Head?
The 700MOBRK8353503Z One Light Head is a modular low-voltage lighting fixture designed for precision illumination. It houses a field-replaceable 12-watt LED module that delivers approximately 740 lumens, and offers selectable color temperatures of 27000 K (cool white), 3000 K (warm white) or 3500 K (neutral white). The unit is compatible with both electronic and magnetic low-voltage dimmers, allowing smooth dimming across the full range. Optics can be swapped between 20° and 35° beam spreads, and an integrated lens holder accepts up to two MR16-size lenses or louvers (sold separately), giving installers flexibility to shape light distribution for a variety of environments. The module can be swapped without tools, simplifying service and extending product lifespan.

Who is 700MOBRK8353503Z One Light Head for?
This fixture targets professional electricians, interior designers, and boutique owners who need a reliable, adjustable light source in residential, hospitality, or small-commercial spaces. Its modular nature makes it ideal for projects where future upgrades or maintenance are expected, such as upscale restaurants, art galleries, or high-end residential kitchens that demand precise beam control and color consistency. Because the head operates on low voltage, it reduces heat output, making it safe for ceiling-mounted installations in tight spaces.
How does 700MOBRK8353503Z One Light Head compare?
Compared with standard fixed-beam low-voltage fixtures, the One Light Head offers greater adaptability through its replaceable LED module and selectable optics. While generic MR16 fixtures often lock in a single beam angle and color temperature, this unit lets users fine-tune illumination without rewiring. Its dimming performance matches that of dedicated dimmable LED modules, but the requirement to stay below 33 % of transformer capacity for inrush current distinguishes it from higher-wattage alternatives that may overload low-voltage systems. Energy consumption stays at 12 W, delivering high lumen output while keeping electricity costs low.
Best use cases
- →Upscale restaurant pendant lighting.
- →Boutique display accent lighting.
- →High-end residential kitchen task lighting.
- →Art gallery spotlighting with custom lenses.
Is One Light Head right for you?
Buy the 700MOBRK8353503Z One Light Head if you need a versatile low-voltage fixture that can be fine-tuned for color and beam angle. It suits professionals comfortable with transformer calculations and lens selection. For projects that demand higher wattage or larger optics, consider standard MR16 fixtures or integrated LED downlights as alternatives. Ensure your transformer can support the 12 W module and follow the 33 % rule to avoid overload.
How it compares: Compared with generic MR16 downlights, the One Light Head offers replaceable LEDs, selectable optics and broader color-temperature options, while standard fixtures lock in a single beam and color, limiting flexibility for designers. They also require careful transformer sizing, whereas many fixed MR16 units draw higher wattage without such constraints.

Frequently Asked Questions
What is the warranty on the 700MOBRK8353503Z One Light Head?
▾
Starlight Lighting provides a standard two-year limited warranty covering defects in materials and workmanship for the One Light Head. The warranty does not include damage caused by improper installation, exceeding transformer capacity, or use of incompatible dimmers. For warranty service, retain the original receipt and contact the vendor’s support team with the SKU 445577.
Does the LED module need a specific transformer?
▾
The LED module is designed for low-voltage (12 V) transformer systems. It works with both electronic and magnetic dimmers, but the transformer must be sized so that the module’s 12 W draw does not exceed 33 % of the transformer’s maximum wattage to prevent inrush current issues. Consult the transformer’s specifications or technical support for exact sizing.
How do I change the optics angle?
▾
To change the optics, first power down the circuit and remove the head from its mounting. Unscrew the existing optic housing, then insert the desired 20° or 35° optic module, ensuring it seats securely. Reattach the head, restore power, and verify the beam spread with a light meter if precise control is required.
Is the One Light Head suitable for outdoor use?
▾
The One Light Head is rated for indoor low-voltage applications only. Exposure to moisture, temperature extremes, or direct sunlight can compromise the sealed optics and electronic components. For outdoor projects, select fixtures specifically rated for IP65 or higher protection and compatible with weather-proof LED modules.
Can I install two MR16 lenses simultaneously?
▾
Yes, the integrated lens holder is designed to accommodate up to two MR16-size lenses or louvers at the same time. Each lens can be selected to achieve a combined beam pattern, but ensure the total light output does not exceed the fixture’s rated 740 lumens and that the lenses are securely fastened to avoid vibration.
