?   Vragen & antwoorden over deze light source van 4 watts

When should I choose the 4W amber ST64 instead of the 6W?
The 4W provides the softest, most intimate light (360 lm)—ideal for small table lamps and wall fixtures. The 6W provides more light (540 lm) for larger spaces.
What makes the ST64 filament bulb unique?
Its slender bulb shape with a visible filament spiral refers to classic filament bulbs. The silhouette is decorative in its own right in open fixtures and pendant lights.
What type of dimmer do I need?
The ST64 uses Triac leading-edge dimming. Use an LED-compatible Triac dimmer. The dimming range is 5% to 90%.
Is there also an on/off variant?
Yes, the ST64 4W amber is also available as an on/off variant without dimming for a lower price.
Does it emit UV or IR radiation?
No—it is safe for artwork, textiles, and sensitive materials.
Is the filament spiral visible through the amber bulb?
The glow of the spiral is visible but softened by the amber glass—this enhances the nostalgic atmosphere.
What is the lifespan?
20,000 hours—at 8 hours per day, more than 6 years.
What warranty applies?
2-year manufacturer’s warranty.
