Product Description
Lucide ST64 is a clear-glass filament LED bulb with an elongated teardrop form and visible light filaments. It suits open pendant or table fittings where the bulb itself becomes part of the interior. The transparent envelope and all-round light retain the visual character of a decorative incandescent bulb.
The bulb has an E27 base, 4.9 W power and 450 lm light output. Lumens allow brightness comparisons, while watts describe electrical power consumption. Check the fitting’s base and permitted bulb power before choosing.
The colour temperature is 2700 K — warm white. Kelvins describe the white-light tone rather than brightness. Colour temperature is fixed, so dimming changes brightness while retaining the same white tone.
CRI 80 describes colour rendering compared with reference light. It helps assess how surrounding objects will appear under the light. The LED source’s 360° beam angle means light spreads around the source.
The manufacturer’s rated LED lifespan is up to 15,000 h. This describes accumulated operating hours, not the warranty period. The specification also states 7,500 on/off cycles, a separate switching-endurance measure that should not be confused with operating hours. The source’s energy efficiency class G on the A–G scale helps compare efficiency; class A is the most efficient on this scale. The energy label is separate from electrical protection class.
The bulb is dimmable with a compatible LED dimmer. Choose a dimmer that supports the combined lamp load and manufacturer-stated compatibility. It allows softer evening brightness while retaining the same white-light tone; the dimmer is not included.
Overall bulb dimensions are 6.4 × 6.4 × 14.6 cm — length, width and height; net weight is 0.06 kg. Check both envelope diameter and height so the bulb fits inside the shade and clears the fitting’s structure.
The bulb is intended for 230 V operation and IP20 use in dry indoor locations. IP20 provides no water protection, so use it in a suitable fitting and keep it dry. The manual specifies 220–240 V AC, 50 Hz.
