Moving Head Light Buying Guide: Beam vs Wash, Beam Angle and Channel Modes
Bagikan
A moving head is the fixture buyers ask for by name. It is also the fixture most often bought on the wrong specification, because "moving head" covers beam, wash and hybrid heads that share a yoke but do completely different jobs on the plot. This guide is for clubs, rental companies and distributors buying moving heads in volume: how to tell the types apart, what part of the specification actually decides the look, and what to confirm before a container leaves the factory.
If you are still choosing the overall rig, our stage lighting equipment guide lays out a full zone-by-zone plan.
Beam, wash or hybrid: the three moving head jobs
Start from the job, not the wattage. A moving head does one of three things, and they are not interchangeable on a plot.
- Beam. A tight, raw shaft of light — the "finger" that cuts across a room. A beam head is about distance and impact, not coverage.
- Wash. A soft, wide pool of colour with no hard edge. A wash head is about covering a surface or a crowd evenly, and it lives or dies on zoom range.
- Hybrid / effect. A beam head that also carries rotating gobos, a prism, a strobe section or a laser. This is the category most venues should default to, because one fixture then covers two or three jobs on the plot.
The mistake we see most often is specifying a beam head where a wash was needed, or vice versa, then trying to fix it with programming. Pick the optics for the job first.
Beam angle and throw: the number that decides the look
Beam angle is the single most useful number on a beam head, because it sets how far the shaft stays tight before it blooms. A 2° beam throws a sharp line across a full room; a wide beam washes out within a few metres. The table below is the published geometry of fixtures in this range.
| Fixture | Beam angle | Best used for |
|---|---|---|
| 120W RGBW beam moving head | 2° | Bars, small stages, tight audience shafts |
| 200W RGBW beam moving head | 2° | Mid-size rooms where the 120W won't reach |
| 295W beam moving head | tight beam + 16 gobos | Concert side-light, beam arrays |
| 19x15W zoom wash moving head | 10°–60° | Soft coverage, colour washes |
A 2° beam reads as a thin line at distance and is exactly what most buyers picture when they search for a beam moving head. The zoom wash sits at the other end: at 10° it is a focused spot, at 60° it is a broad even wash, which is why a single zoom fixture can replace two fixed-angle units in a rental inventory.
The workhorse beam heads: 120W and 200W rainbow
The rainbow beam series is the volume seller in this catalogue, and the two models are the same optical package at different output levels.
- The 120W RGBW beam moving head with rainbow ring runs an 8-facet and 18-facet prism on a 2° beam, with 8 gobos, 8 colours and a chasing rainbow LED ring that reads well on camera. Pan 540° / tilt 180°, 15 DMX channels, aluminium-and-ABS body.
- The 200W RGBW beam moving head with rainbow effect keeps the same 2° beam and gobo package but roughly doubles the output — the model for venues where the fixture has to throw across a full room. 12 DMX channels.
Both run DMX512, auto, master/slave and sound-active, and the 120W adds an IR remote for walk-in gigs. For a bar or a mobile DJ, that is the whole feature set in two boxes.
The high-output beam: 295W with gobos
The 295W professional beam moving head is the step up for concert side-lighting and beam arrays: 16 gobos and a honeycomb prism for the multi-facet fan effect that reads at distance. It is the fixture to specify when the room is large enough that the 120W/200W models no longer reach, and it is the unit most rental houses build their beam packages around.
The effect heads: double-sided and 3-axis
Two heads in this range are built to be the visual centrepiece rather than a supporting beam.
- The 280W double-sided beam moving head rotates 360° continuously, so the whole assembly sweeps rather than panning back and forth — useful as a feature fixture on a stage centre or a DJ booth.
- The 3-axis RGBW laser beam moving head rotates on X, Y and Z instead of the usual two axes, so the beams tumble through space. It pairs four 10W CREE 4-in-1 LEDs with a 100mW green laser and gold strobe chips (14 DMX channels, 100W). It is the single most-commented effect in our demo footage and an easy upsell for distributors.
Wash moving heads for soft coverage
Where the plot needs colour rather than a shaft, the wash heads take over.
- The 19x15W RGBW zoom wash moving head runs a 10°–60° zoom, so one fixture covers both a tight spot and a wide wash. Nineteen 15W RGBW LEDs give a smooth, even field with no visible hot spot.
- The 19x15W RGBW wash moving head with halo ring adds a glowing RGB ring around the lens — a look that reads on camera and works as a standalone feature on a booth or a low truss.

DMX channel modes: what the counts actually buy you
A moving head offered in several channel modes is not padding its spec sheet. The modes solve different problems, and the choice changes how much of the console you use.
- Low-channel mode maps the head to a small block of channels: pan, tilt, colour, gobo, strobe, dimmer. It is fast to patch and easy for a visiting operator to pick up — right for a bar or a fixed install.
- High-channel mode exposes pan and tilt fine, plus each gobo wheel, prism, ring and colour independently, so you can write shapes and cues the low mode cannot. This is the mode you plan a show file around.
The practical rule: if you are writing cues, buy the higher mode and patch for it; if door staff will run sound-to-light, the higher mode is dead weight. For the fundamentals of addressing and universes, our DMX512 control guide covers them.
Power, rigging and the limits of the room
Moving heads are heavier and draw more than pars, which is where installs go wrong. Three checks settle most problems before they happen:
- Weight and rigging point. A head is suspended for its whole life. Use rated clamps and a secondary safety bond, and confirm the truss rating before you hang a row of them.
- Current per fixture. Take the real draw from the rating plate on the production unit, not the headline wattage, and confirm the maximum number of heads the manufacturer permits on one power link.
- Thermal behaviour. Ask what the thermal protection does after three hours at full output — a head that dims itself mid-set is worse than one that runs cooler by design.
Export packing: carton maths that decide landed cost
Moving heads are small and dense, so you are paying freight on weight rather than volume — the opposite of par cans. The figures you need before comparing landed cost are the single carton size, the quantity per master carton and the gross weight. The 120W and 200W rainbow heads ship roughly 4 pieces per carton; the 3-axis laser beam head ships 4 pieces per carton at about 15 kg gross. Ask for the 20GP and 40HQ container loading figures on the exact mix you are ordering — a mixed pallet of beam and wash heads will not load the same way as a single-model container, and the difference is real money at volume.
Frequently asked questions
How many moving heads does a club need?
For most 200-500 capacity rooms, four to eight beam or wash heads is a working starting point: a pair front-of-house for audience shafts, a pair on the downstage truss for colour, and two or four more as feature or effect heads. Scale from there by room height and whether the brief needs beams, washes or both.
Beam or wash for a small club?
If the room is low and you want colour on the crowd, wash heads (or zoom heads at wide angle) do the job. If you want shafts that cut across the room and read from the bar at the back, beam heads are the answer. Most small venues are happier with one or two beams for accent and a few washes for coverage than with a wall of beams.
Can moving heads be used outdoors?
Only with an appropriate ingress protection rating. The standard heads in this range are indoor fixtures. For covered terraces or open-air stages, start from a fixture with a published IP rating — our IP65 outdoor lighting guide explains what those ratings actually protect against.
