Description
The 70W SON-E E27 is a high-pressure sodium (HPS) lamp with an elliptical (E-shape) bulb and a standard E27 Edison Screw base, used primarily for public and industrial lighting. The key feature of the “E” type (elliptical) is a white diffusing inner coating, which broadens the light distribution, unlike the clear “T” (tubular) version used for precise optical control in floodlights.
Key Features & Details
- High Efficiency: The lamp is highly energy-efficient, offering a high luminous efficacy (around 80 lm/W for standard models) with a bright output of approximately 5,600 to 6,270 lumens.
- Long Life: It boasts a long average lifespan, typically ranging from 28,000 to 36,000 hours, which reduces maintenance frequency and costs.
- Warm Light: It emits a golden-white, warm light with a color temperature of around 2000K, ideal for residential areas, car parks, and general road lighting where accurate color rendering is not the main priority.
- Ignitor Type: SON-E lamps are available in both internal and external ignitor versions. It is crucial to check the original lamp or fixture specifications to ensure the replacement is compatible (often indicated by an “I” on the lamp).
- Requires Ballast: Like all high-intensity discharge (HID) lamps, the 70W SON-E lamp requires a compatible external ballast and ignitor to operate. It is not a direct replacement for incandescent or LED bulbs.
