Moving Head Types: Beam, Wash, Spot & Effect Compared
Bagikan
A balanced rig is a mix of moving-head families, each doing a different job. Knowing the four types prevents a rig that is all beams and no wash — or all wash and no punch. Here is a field guide to the families, example rigs, and the practical limits you need to plan around.
The four families
| Beam | Sharp shafts, long throw |
|---|---|
| Wash | Soft, wide color fill |
| Spot | Focused pool + gobos |
| Effect | Arms, lasers, multi-mirror novelty |
Where each belongs
- Beam — back truss, cutting through haze.
- Wash — front fill, color washes, face light.
- Spot — logos and patterns on a wall or floor.
- Effect — energy moments, ceiling and wall animation.
A simple ratio
For a mid-size club, a common starting point is 40% wash, 30% beam, 20% spot, 10% effect. Adjust to your room and music.
Example rigs by budget
Small bar (under 12 heads): 5 wash, 4 beam, 2 spot, 1 effect. Medium club (20 heads): 8 wash, 6 beam, 4 spot, 2 effect. Large venue (40+): scale the same ratio and add a second truss for front wash. Keep spares for the most-used family — wash heads fail least, beams get knocked most.
Rigging weight and power
Total the weight of every head plus clamp and cable, then confirm truss and motor ratings with a safety factor. Power is usually the real limit: a rack of 230W spots can draw several kilowatts, so distribute across circuits and use a measured load plan. A clean power distro prevents the dreaded dimmer dip during the drop.
Recommended GFlight heads
- Moving Head Face/Wash 180W — front wash.
- 18-LED RGBW Moving Head Par — zoom wash/beam.
- 3-Arm Beam Laser — effect moment.
- 230W Beam Spot — hybrid punch.
- 60W Prism Beam — entry beam.
How many heads per truss
A front truss typically carries wash heads aimed at the stage; a back truss carries beams into the haze; side pods add coverage. For a 200-cap room, 8–12 heads split across two truss positions is plenty. Heavier rooms scale the same ratio rather than cramming one truss past its safe load. Always confirm truss and motor ratings before adding heads.
Wash heads: zoom vs fixed
A fixed wide-angle wash is cheaper and great for static color, but a motorized zoom (10°–60°) lets one head wash a tight singer or flood a wide stage. If budget allows, zoom wash heads are the most flexible single purchase in a rig.
Spot heads: gobo library tips
Build a small, repeatable gobo set: a company-logo disc for branding moments, a breakup pattern for texture, and a simple ring for emphasis. Swap discs between shows rather than buying a new head for each look. Keep gobos clean — dust scatters light and softens the projection.
Effect heads: help vs distraction
Effect heads (arms, mirrors, lasers) are energy moments, not continuous looks. Use them for the drop and the finale, then park them. Overusing effect heads makes a rig look chaotic and buries the music. A little novelty goes a long way.
Balancing the rig on a budget
If the budget only covers a few heads, prioritize wash first (most-used), then add beams for moments, spots last for logos. A rig that is 60% wash still looks complete; an all-beam rig looks empty during songs. Borrow or rent the specialist heads for one-off big shows rather than buying them.
Documenting your rig for the next gig
Photograph the rig and save a patch list after every show: fixture type, DMX start address, position, and any faults. A five-minute photo at teardown saves an hour of re-discovery next load-in. Over a season this becomes a library you can quote from, so clients get consistent looks and you stop reinventing the plan each weekend.
Frequently asked questions
Can one head do everything?
Beam-spot hybrids cover a lot, but you still want dedicated wash for soft fill.
Wash or par for face light?
A moving wash head reaches and shapes better; a par is cheaper for static wash.
How many heads for a small club?
Roughly 8–12 heads mixed covers most 200-capacity rooms.
Should beginners buy beams or wash first?
Start with wash — it is the most-used family and the safest to learn on. Add beams once you understand haze and throw, and spots once you need logos.
How do I learn to program heads?
Start with manufacturer presets, then build simple position and color palettes. Practice on a test truss before a paid show; muscle memory beats reading the manual live.
Which family fails most often?
Beams take the most physical knocks; wash heads fail least. Carry spare clamps and a spare wash head, and label everything so a swap is fast.
