What's happening
Amlux's gobo dichroic filters are custom borosilicate (tempered) glass available in standard Pantone colours (e.g. Red Pantone 186 C, Blue 286 C, Green 355 C) with 1.1mm/0.5mm thickness and 14–180mm diameter. The dichroic process gives longer lifetime without colour loss and without absorbing light (no overheating), resisting high temperature up to 450°C.
Why it matters for buyers
For a retailer, venue or signage buyer, the practical effect is simple: the unit that reads on your wall at your ambient light, with your artwork, beats the one with the bigger number on the box. Specification order — distance, image size, ambient, then brightness — decides the result.
It also changes lead-time risk. Custom gobos and certified outdoor builds need briefing before the date is fixed; the projector is rarely the long pole, the artwork and certification are.
The technical angle
Colour filters cost output. Every added filter layer absorbs a slice of light; a three-colour stack can lose 40–60% of beam brightness. Quote the filtered lumen figure, not the bare lamp lumen, when comparing.
What to specify
Before you request a quote, lock these down:
- Image size you need at that distance
- Mounting surface and whether the bracket can hold aim
- Lead time on a custom gobo versus a stock pattern
- Ambient light level at the hour the projection must read
