Compare at the same distance, on the same surface
Compare at the same distance, on the same surface, at the same hour. Every meaningful difference between a colour wheel vs fixed filter and the alternative shows up there and nowhere else — on a spec sheet both options look capable. Set up the comparison on the wall you actually have, and the decision usually makes itself.
- Throw distance and image size, fixed for both options
- The surface and the ambient light at the working hour
- The artwork, and whether it contains text or fine detail
- How each option will be serviced
Light source and output
Compare output at the wall, not at the lamp. LED efficiency varies widely between bins and drivers, so a colour wheel vs fixed filter quoting fewer lumens can deliver more lux through a better lens. If the supplier cannot give you a measured figure at a stated distance, treat the comparison as unreliable.
- Instant strike and tolerance of frequent switching
- Output stability over the duty cycle
- Driver quality and thermal design
- Measured output at the wall, not rated lumens
The bill after the first year
Service life is a design outcome, not a datasheet number. Compare how each option handles heat, whether routine servicing breaks the environmental seal, and how quickly a replacement gobo can be produced. Those three things determine whether the unit is still doing its job in year three.
The short version
The short version: one option wins on image freedom, the other on raw output or simplicity. Which matters depends entirely on whether you are projecting a mark or an effect. Decide that first and the rest of the table reads itself.
| Criterion | Colour Wheel vs Fixed Filter | The alternative |
|---|---|---|
| Text and logo detail | Full vector and halftone | Limited or none |
| Colour control | Filter or coated gobo | Fixed or source-dependent |
| Servicing access | Gobo swap, lens clean | Depends on design |
| Changeover time | Minutes with a spare | Varies widely |
How to choose
If you are still unsure, buy one of each and put them on the wall for a week. Differences that look marginal in a table are unmistakable on site, and one colour wheel vs fixed filter is a small price to pay for getting a rollout right.
- Does the job need text, a logo or fine detail
- Is the surface and ambient light controlled
- How often will the artwork change
- How will it be serviced in year three
