An elliptical-dimpled outer-envelope format associated with compact HID lamps and modern LED retrofit products.
ED means elliptical dimpled, referring to the elongated outer bulb and its shaped end. ED17 has a nominal maximum diameter of 17 eighths of an inch, approximately 2⅛ inches.
Area lights, wall packs, post-top fixtures, commercial interiors, retail high ceilings, industrial fittings and legacy HID systems.
ED17 envelopes are used for metal-halide, high-pressure-sodium and other HID lamps, as well as selected LED replacements with medium or mogul screw bases.
Technologies represented in this library: HID, LED.
Available base types: E26, E27, E39, E40.
| Technology | Common wattage range | Typical lumen range | Common colour temperatures | Common voltage options |
|---|---|---|---|---|
| HID | 35–250 W | 2500–28000 lm | Approximately 1900K–4200K, depending on HID technology | Ballast-operated |
| LED | 15–80 W | 2000–12000 lm | 3000K, 4000K, 5000K, 6500K | 120–277V; 220–240V; retrofit-specific |
These are representative market ranges, not guaranteed limits. Availability varies by manufacturer, voltage, base, beam, region and product generation.
Identify the exact lamp code, technology, wattage, base, ballast, starting method, operating position and fixture rating. For LED retrofits, confirm whether control gear must be removed.
Sharing an ED17 envelope does not make HID lamps interchangeable. Ballast type, ignitor requirements, pulse rating, operating position and base must all match.
Important: The library describes a lamp format, not a particular product. A shared shape does not guarantee matching voltage, base, dimensions, light distribution or control-gear requirements. Confirm the fixture label and product datasheet, or ask a Bulb World lighting specialist.
