GTAREN 100W LED Corn Cob Light Bulb
The GTAREN 100W LED corn light is designed to replace 400W MH/HPS/HID lamps in mogul-base fixtures. It delivers up to 13,000 lumens at 5000K and uses a built-in driver with no ballast. The lamp claims energy savings of roughly 90% vs. incandescent and 60–70% vs. traditional LED equivalents, with a projected lifespan of several years under typical use. It is not dimmable and requires ballast removal before installation. Size is listed as 4.4 x 4.4 x 10 inches.
115W LED Shoebox Retrofit Lamps
These 115W shoebox retrofit lamps from LED Flying Direct offer around 15,525 lumens at 5000K and are designed for 100–277V operation. They feature a rotatable E39 Mogul base and claim up to 95% efficiency, with an estimated life of 50,000 hours. The design emphasizes quick installation and directional lighting, making them suitable for parking lots and street lighting fixtures. The product notes highlight strong heat management and a long service life, reducing maintenance in large-area applications.
Sunlite MH400/U/MOG M59 Metal Halide Lamp
Sunlite’s 400W MH lamp provides a direct replacement option that delivers approximately 36,000 lumens at 4000K. It uses a Mogul base (E39) suitable for street lighting, parking infrastructure, and large-area fixtures. The product emphasizes high efficacy, good color rendition, and a robust service life typical of HID lamps. When retrofitting, ballast removal and fixture compatibility should be verified for optimal performance.
BBESTLED 150W Retrofit Kit
The BBESTLED retrofit kit packs 150W of LED power with a claimed output of around 21,000 lumens at 5000K. It’s designed to replace 400–550W MH/MHL/HID fixtures in outdoor and industrial settings and comes with adjustable mounting hardware. Certifications such as ETL and DLC are highlighted, supporting reliability and potential energy savings of up to 80% compared with legacy systems. Installation notes emphasize removing or bypassing the ballast and confirming fixture size before mounting.
Sylvania LED High Lumen Retrofit Corn Lamp
The Sylvania LED High Lumen Retrofit Corn Lamp offers an EX39 mogul-base retrofit with 16,200 lumens at 3000K. It targets 400W-equivalent performance with reduced energy consumption—up to 76% less energy for the same light output. The lamp advertises a long rated life of up to 50,000 hours and is positioned as a practical replacement for outdoor and commercial interior applications where color warmth matters. It may be best suited for locations desiring a warmer light appearance than 5000K options.
Buying Guide: Key Considerations for 400W MH/LED Retrofits
- Compatibility with fixtures: Verify Mogul base size (E39) and ballast bypass requirements. Some lamps require direct-wire setups without ballasts.
- Lumens and efficiency: Compare lumen output and efficacy (lm/W). Higher lumens and efficiency reduce energy costs and improve lighting coverage for large areas.
- Correlated Color Temperature (CCT): Choose 4000K for a neutral white or 5000K for daylight-like brightness. 3000K offers a warmer appearance ideal for certain environments.
- Color rendering index (CRI): A higher CRI improves color discrimination, valuable in outdoor, garage, and warehouse work areas.
- Lifespan and maintenance: Longer lifespans reduce replacements and labor costs in hard-to-reach fixtures.
- Warranty and certification: Look for ETL/DLC certifications and manufacturer warranties to ensure reliability and eligibility for energy rebates.
- Installation: Assess mounting options, including rotatable bases and easy-fit adapters. Some kits include adapters for E26 or E39 bases.
- Heat management: Effective cooling (fans, aluminum housing) extends life and preserves brightness over time.
- Voltage range: Ensure the product supports your local voltage (commonly 120–277V), particularly for outdoor fixtures.
When selecting a retrofit, consider the fixture type (canopy, shoebox, bay lighting) and the physical size of the lamp to ensure a proper fit and adequate light distribution. Testing a sample in a small area can help verify performance before wide-scale replacement. Always follow local electrical codes and safety guidelines during installation.
