LED Moving Head Light Specifications Buyers Need to Know

Understanding the core specifications of a professional LED moving head light

Why specifications matter for different applications

When evaluating an led moving head light, specifications determine whether a fixture will perform as needed in a club, theater, touring rig, studio, or outdoor event. Buyers must match photometric output, optical characteristics, mechanical performance, control features, and ruggedness to their intended use—otherwise a light may be underpowered, too noisy, or incompatible with control systems.

Key categories of specifications to check

Top-level categories include photometrics (lumens, lux, beam angle), optics & effects (gobos, prisms, zoom), mechanical/motion (pan/tilt range & speed), control (DMX channels, protocols), electrical & thermal (power draw, cooling), environmental rating (IP), and serviceability (warranty, spare parts).

Photometrics and optical performance

Lumens, lux and throw distance

Manufacturers often list lumen output and lux values at specific distances. Lumens describe total light emitted; lux describes illuminance at a surface (lumens/m²). For stage work, lux at a given throw distance (e.g., 5 m) is more useful. Always request or calculate lux charts from the manufacturer or test data. Typical LED moving heads range from 5,000 lm (compact wash/spot) to 60,000 lm (high-output moving-head profiles).

Beam angle, zoom range and spot vs wash vs beam

Beam angle and zoom range directly affect the fixture’s application:

• Beam moving heads: narrow beam angles (1°–6°), designed for aerial beams and long throws.
• Spot/profile heads: medium beam angles (6°–20°) with sharp focus and gobos.
• Wash heads: wide beam angles (10°–70°) with soft edges and broad color mixing.

Confirm the zoom ratio (e.g., 5°–50°) to ensure coverage and intensity across distances.

Optics, gobos, prisms and effect modules

Look for glass gobos vs metal gobos (glass gives finer detail), number of gobo wheels, indexable prisms (3-, 4-, 6-facet), and built-in effects like frost, iris, and framing shutters. These determine creative flexibility and cost.

Color systems, CRI, and broadcast considerations

Color mixing: RGB, RGBW, CMY, CTO and white engines

Color systems vary:

• RGB or RGBW: common for vibrant colors; RGBW adds white for better pastel & white rendering.
• CMY (subtractive mixing): excellent for smooth color gradients and accurate whites.
• CTO/CTB or variable CCT: useful for matching studio or theatrical color temperatures.

Choose fixtures with the color system matching your needs: broadcast/studio work favors high CRI and variable CCT; concerts favor saturated colors and fast color macros.

CRI, TLCI and flicker-free operation

For accurate color rendering, especially in video, check CRI (Color Rendering Index) and TLCI. Aim for CRI > 80 for general stage use, > 90 for camera-critical applications. Also verify flicker-free performance at common camera frame rates—manufacturers should specify PWM frequencies or list “flicker-free for broadcast”.

Color temperature range and presets

Fixtures often provide adjustable CCT (e.g., 2,700K–8,000K) and presets for tungsten and daylight. Confirm whether CCT adjustment is continuous and whether the fixture supports CTO for warm looks.

Control, channels, and connectivity

DMX channels, protocols, and modern control options

DMX512 remains the baseline control protocol. Pay attention to channel modes: compact mode (16–24 channels) vs full-featured mode (40–60+ channels). Modern fixtures often support RDM (remote device management), Art-Net, sACN (streaming ACN), and sometimes wireless protocols. For complex fixtures, RDM simplifies addressing and status monitoring.

Presets, onboard programs and pixel mapping

Fixtures with onboard show memory, standalone operation, or pixel-mapping capability can operate without a full console. For LED matrix or bar fixtures, pixel mapping and multiple pixel outputs can be crucial. For moving heads, look for multi-fixture synchronized effects and fixture grouping options.

Control connectors and power options

Check physical connectors: 3-pin vs 5-pin DMX, Neutrik powerCON or IEC mains. For touring use, robust locking connectors and compatibility with global voltages (100–240V auto-switching) are important.

Mechanical performance, build quality and serviceability

Pan & tilt range, resolution, and movement speed

Typical professional moving heads offer 540° pan and 270° tilt, with high-resolution stepper or encoder feedback for smooth motion. Faster movement speeds help follow spots and quick effects. Verify the fixture’s movement response, backlash specifications, and whether it offers position feedback for automated systems.

Cooling, noise and operating environment

Cooling affects LED life and noise level. Passive-cooled fixtures are silent but limited in output. Active-cooled fixtures use fans—check dBA ratings if using in small theaters or studios. For outdoor or dusty venues, look for sealed optics and efficient thermal pathways.

IP rating, materials and weight

For outdoor events, IP65 or higher is required. Indoor fixtures commonly are IP20. Assess housing materials (die-cast aluminum vs plastic) and overall weight, which affect truss loading, rigging hardware, and transport logistics.

Electrical, safety and longevity

Power consumption and energy efficiency

Confirm maximum wattage, inrush current and power factor correction. LED moving heads are far more energy-efficient than discharge-based fixtures; still, high-output models can draw 700–2,000 W. Calculate total load for dimmer racks and generators.

LED lifespan and maintenance intervals

LED modules typically list L70 or L90 lifespans (e.g., 50,000–100,000 hours). Understand which components are user-serviceable: fans, lenses, and gobos. Ensure spare parts availability and local service networks to minimize downtime.

Certifications and warranty

Check CE/UKCA/ETL/UL marking, safety agency approvals, and warranty length. For rental companies, extended warranty and fast spare parts are critical. Also confirm compliance with regional EMC regulations.

Practical buyer checklist

1. Define the primary application (touring, theater, broadcast, club, outdoor).
2. Match lumen/lux output to venue size and throw distance—ask for photometric charts.
3. Verify color rendering (CRI/TLCI) and flicker-free specs for video work.
4. Check control modes & channel counts for your console and network.
5. Assess noise level, cooling, and IP rating for environment.
6. Confirm connectors, voltage compatibility, and power draw for power budgeting.
7. Ask about spare parts, local support, warranty, and firmware update paths.
8. Request sample units or on-site demos when possible.

Cost, total value and long-term ownership

TCO considerations beyond initial price

Total cost of ownership includes purchase price, shipping, rigging hardware, power consumption, spare parts, maintenance labor, and depreciation. Higher up-front cost for better optical components and cooling often reduces downtime and replacement frequency.

Rental vs purchase decision factors

Rental houses prioritize durability, easy field service, and availability of spares; venues may prioritize quiet operation and lower power draw. For production companies, modularity and compatibility with existing ecosystems are essential.

Trade-offs: weight vs output vs cost

High-output fixtures usually weigh more and cost more. If portability is key, look for mid-output units with efficient optics and LED engines that optimize lumens-per-watt.

FAQ — Frequently Asked Questions

1. What does “lumen” vs “lux” mean and which should I use?

Lumen measures total light output from the fixture. Lux measures illuminance at a surface at a given distance. For stage and venue planning, lux at your working distance is more actionable. Request lux charts (photometric) from the manufacturer.

2. How do I calculate the number of fixtures needed for my stage?

Start with a target lux level for the application (e.g., 300–750 lux for general stage, higher for television). Use the manufacturer’s lux-at-distance chart and factor in beam angle and throw distance. Allow headroom for dimming and fixture aging.

3. What is the difference between RGBW and CMY color systems?

RGBW mixes red/green/blue with an added white LED for improved pastel and white reproduction. CMY is an analog subtractive mixing system (cyan/magenta/yellow) offering smoother color control and more accurate whites in some theatrical applications.

4. Can moving head lights be used outdoors?

Yes, but only if rated for outdoor use (IP65 or higher). Indoor-only fixtures (commonly IP20) are unsuitable for rain, dust, or high-humidity conditions without additional protection.

5. How important is RDM and Art-Net support?

RDM allows remote addressing and status monitoring—very useful for large installs and touring. Art-Net or sACN support enables network-based control for complex distributed systems. If you run modern lighting networks, these features are highly recommended.

6. What maintenance should I expect for LED moving heads?

Regular checks include cleaning optics and air filters, fan replacement as needed, firmware updates, and verifying mechanical parts (gears, belts). Follow manufacturer-recommended service intervals.
