Prices are a guide for the minimum order, FOB, per piece; your quotation is what binds us.
The ST64 is the bulb that sells our pendants: the spiral filament stays visible through amber glass, and at 2200 K it reads like a carbon filament while drawing a tenth of the power. We make the filament strips, the driver and the glass envelope in-house and seal each lamp in nitrogen.
Every lamp is burned in for eight hours at 45 °C and dim-tested on two dimmer types before it is boxed. Box artwork, glass tint and base are made to order from 3,000 pieces.
