Set the comparison on the same wall
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
Where the brightness comes from
Where the brightness comes from determines what you can do with it. An LED business logo projector 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
Image quality and artwork freedom
Ask what each option can actually draw. Fine strokes, gradients and photographic detail need an engraved glass gobo and a lens that can resolve it; simpler effects do not. Buyers often pay for capability they never use — or discover too late that the cheaper option cannot render the artwork they already approved.
- 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
Running cost, heat and service life
The purchase price is the first payment, not the last. LEDs in this class are rated in the tens of thousands of hours to L70, but that figure assumes reasonable thermal management — a business logo projector cooking in an enclosed void will not reach it. Add gobo replacement, cleaning access, and the cost of the electricity, and the ranking often changes.
- 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
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.
Decide on the job, not the datasheet
The decision is usually obvious once the artwork is fixed. Text and brand marks need the business logo projector; washes and abstract movement do not. Where it stays genuinely close, buy the one that can be serviced from a ladder — that will be the difference you remember in year three.
- 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
