2-Pack 100W LED Corn Cob Light Bulb E39 Mogul Base - Bright High Bay

In this review of the 2-Pack 100W LED Corn Cob Light Bulb, the bottom line is simple: this kit is for anyone who needs a bright, energy-efficient replacement for old metal halide or HPS fixtures in large spaces. It delivers a very high lumen output and straight-forward installation into an E39 mogul base, making it a practical choice for garages, warehouses, parking lots and outdoor wall packs. The major selling point is the light output and energy savings, while buyers should be aware of mixed reports on long term lifespan and occasional flicker.

Key Features

• Brightness: Produces up to 14,000 lumens at about 140 lm per watt, offering intense illumination for large, dim areas.
• Energy Savings: Replaces 250-400W MH or HPS bulbs and cuts energy use by roughly 80 percent compared with those older HID options.
• Easy Installation: Uses an E39 mogul base and simply screws into an appropriate socket after ballast bypass, avoiding a full fixture replacement.
• Durability: Rated life of 50,000 hours, which is substantially longer than traditional CFL, MH or HID bulbs and reduces replacement frequency.
• Weather Resistance: IP64 wet location rating means it is dust resistant and can handle wet conditions for outdoor and semi-exposed installations.
• Versatile Use: Designed for high bay, garage, parking lot and street lighting applications where broad, powerful illumination is required.

Who It's For

This 2-pack is aimed at facility managers, contractors and homeowners who maintain garages, warehouses, high bays or parking areas and want a straightforward upgrade to efficient LED light. The bulbs suit fixtures with an E39 mogul base where bypassing the ballast is acceptable and where high lumen output is the priority.

It is not ideal for small residential rooms or fixtures that cannot accommodate the physical size or heat profile of a corn bulb. Buyers who need guaranteed long-term lifespan without any reports of flicker may prefer to vet a small sample first or consider products with longer proven field lifetimes.

Pros & Cons

Pros

• Very high brightness that effectively lights large outdoor and industrial spaces.
• Significant energy savings compared with 250-400W HID bulbs, lowering operating cost.
• Simple retrofit into E39 sockets with ballast bypass, saving installation time and cost.
• IP64 rating allows use in wet or dusty locations.

Cons

• Some customers reported shorter-than-expected lifespan, with a few bulbs failing within months.
• There are reports of flicker in some installations, so compatibility with dimmers or sensitive fixtures may be an issue.

Our Verdict

The 2-Pack 100W LED corn bulbs are a compelling value for large-space lighting upgrades because they deliver very high lumen output and major energy savings while fitting E39 sockets with minimal work. They are best for commercial and outdoor applications where brightness and durability matter, but buyers should be mindful of mixed field reports on lifespan and occasional flicker and test a small number first in critical installations.

Frequently Asked Questions

Do these bulbs replace 250-400W metal halide or HPS?
Yes, they are designed to replace 250-400W MH/HPS fixtures while using about 100W and offering roughly 80 percent energy savings.

Can I install these without changing the fixture?
Yes, they use an E39 mogul base and can be screwed into the socket, but the existing ballast must be bypassed when switching to LED.

Are these suitable for outdoor wet locations?
They carry an IP64 rating, so they are dust resistant and can handle wet conditions when installed in appropriate fixtures.
