GRUOTVSZAK LU250/MOG 250W HPS Lamp
Best for customers needing the highest measured brightness among similar 250W HPS bulbs. This lamp provides about 30,000 lumens and is designed for Mogul E39 bases with ANSI S50 ballast compatibility. It suits street lighting and large-area fixtures where reliable, long-term performance is essential. Consider this option if you operate installations that require maximum initial brightness and a proven, long life.
Limitations: The color temperature is 2100K, yielding a warm yellow light; this may impact color differentiation in some environments. Also, exact lumen output can vary by ballast and fixture conditions.
Sunlite 03634-SU LU250/MOG 250W HPS
Better for facilities that want a long-life HID solution with a standard ED18/Mogul base. It delivers about 28,000 lumens at 2100K, with ANSI S50 compatibility and a robust 24,000-hour lifespan. This bulb is well-suited for parking lots and perimeter lighting where a balance of brightness and enduring performance is valued.
Limitation: Slightly lower lumen output than the top option. The glass is clear, which can influence sky glow and glare control depending on fixture design.
Delyle LU250 250W HPS Bulb
Designed for industrial settings like warehouses and large parking areas, this lamp produces about 28,000 lumens at 2100K with a standard E39 mogul base. It’s a practical pick for installations that prioritize easy replacement and ballast compatibility. It’s a strong choice for upgrading older lighting to modern HID performance.
Caution: Data notes emphasize typical brightness and longevity; actual results vary with ballast and fixture configuration. Ensure ballast compatibility with S50 standards before purchasing.
Satco S1940 2100K 250W HPS
Accessible choice for users prioritizing a cost-effective 250W HPS bulb with Mogul base. It aligns with ET18/Mogul E39 configurations and is commonly used in street lighting and industrial fixtures. This option is best for budget-conscious projects where standard brightness suffices and ballast compatibility is already confirmed.
Limitation: Specific lumen and life data aren’t listed in the brief; verify expectations with your ballast and fixture assembly before committing.
SYLVANIA LU250/ECO 250W HPS
Best for energy-conscious operations seeking high efficiency and long life. It uses an E39 Mogul base with ET18 shape and offers strong initial lumens around 29,700 with a typical 24,000-hour life. This lamp’s ECO designation implies efficiency emphasis and compatibility with standard high-output fixtures.
Tip: The ECO badge can reflect efficiency improvements; verify fixture compatibility and ballast type to ensure maximal performance.
Buying Guide
- What base and ballast are required? Most 250W HPS bulbs use an E39 Mogul base and ANSI S50 ballast compatibility. Confirm your fixture’s ballast type before purchasing.
- What lumen output do you need? Higher lumens improve area coverage; choose bulbs around 28,000–30,000 lm for large spaces.
- Color temperature matters. All options here are ~2100K, which yields a warm yellow light ideal for outdoor and security lighting; assess if color rendering matters for your application.
- Lifetime and maintenance. A typical life around 24,000 hours minimizes replacement frequency; consider environments with frequent on/off cycles that may affect longevity.
- Electrical and fixture compatibility. Ensure the fixture supports ED18/ET18 shapes and that the operating voltage aligns with the ballast and local supply.
- Availability and replacement parts. Consider brands with readily available replacements and consistent performance.
FAQ
- What is the standard base for these lamps? Most are Mogul base E39 compatible with ANSI S50 ballasts.
- What lumen range should I expect? Typical outputs are 28,000–30,000 lumens depending on the model.
- How long do 250W HPS lamps last? Common lifespans are around 24,000 hours under normal operation.
- Is 2100K color warm or harsh? 2100K is a warm yellow, good for security and outdoor lighting but may affect color distinction.
- Can these be mixed in the same fixture? It’s best to use bulbs with the same or very similar lumen and color temperature for uniform light.
- Do bulbs require special handling? HPS bulbs contain additional gases; handle carefully and dispose according to local regulations.
