Channel Letter Fabricators
Workshops cutting returns, welding backs and facing letters, who need the depth band and the cascade limit published before they cut anything.
Where It Goes Wrong
- A module bought on lumens alone that turns out to be rated for a cavity twice the depth of the letter being built.
- A supplier who will not publish the cascade limit, so the feed points are guessed and then rewired.
- Two deliveries of the same model that do not match in colour on one fascia.
- Modules whose IP rating is quoted for 'the range' and never for the model.
- A pitch chosen from a photograph rather than from the beam angle.
What These Buyers Ask For
- A published depth band for every model, not for the family
- Cascade limits for single-ended and double-ended feeds
- Colour binning stated as a number
- Lumens per piece rather than lumens per metre
- A range that covers 25 mm returns and 200 mm cavities from one supplier
