Compare at the same distance, on the same surface
The comparison that matters is not the one on the datasheet. Two options with similar wattage can differ entirely in what they can draw, how long they last, and what they cost to keep running. Put them side by side on the real surface and rank them on the things you will live with, not the things that look good in a table.
- 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
Where the brightness comes from determines what you can do with it. An LED store logo projection light can be switched, dimmed and cycled without penalty; older sources need warm-up and suffer from frequent switching. For anything on a timer or a sensor, LED is not just more efficient — it is the only sensible choice.
- 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
What each option can actually draw
Detail is the constraint that decides most comparisons. A store logo projection light carrying a custom gobo will reproduce a script monogram cleanly; alternatives that generate the image electronically or mechanically cannot. Check the thinnest stroke in your artwork against what each system holds before you weigh anything else.
- Can it render text and fine strokes
- Does it hold gradients or photographic halftones
- Gobo or pattern changeover time
- Maximum artwork resolution the optics can resolve
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.
- Rated hours and what end of life means
- Cleaning frequency and access method
- Gobo or pattern replacement cost and lead time
- Power draw at the actual duty cycle
Side by side
Set the two options side by side on the criteria that survive contact with a real site: what they can draw, what they cost to run, what they need to stay bright, and how they are serviced. The table is deliberately short — if a criterion does not change the decision, it does not belong in it.
| Criterion | Store Logo Projection Light | 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 |
Decide on the job, not the datasheet
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 store logo projection light 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
