MH100/U/MED 100W Metal Halide Bulb ED17 Medium Base (3 Pack)

In this review of the MH100/U/MED 100W Metal Halide Bulb (3 Pack), the bottom line is simple: this kit is best for users who need bright, dependable outdoor or large-space lighting at a budget-friendly price. The reviewer found the bulbs deliver strong illumination and good value for many applications, while noting mixed reports on long-term lifespan. For those who prioritize initial brightness and light quality for fixtures with an ED17 medium base, this pack is a practical choice.

Key Features

• 100 Watt power: Provides a high output suitable for outdoor security fixtures and large indoor areas that require intense light.
• 14,000 lumens: Delivers very bright illumination so you can see farther and cover wider areas with fewer fixtures.
• 10,000 hour average lamp life: Offers extended runtime under typical conditions, reducing the frequency of replacements for many users.
• ED17 medium base: Fits common medium-base dusk-to-dawn and outdoor fixtures for straightforward installation.
• Clear finish and 5-4/9 in MOL: A clear glass envelope and a compact 5-4/9 in overall length keep the bulb compatible with many enclosures while producing crisp light.

Who It's For

This 3 pack is geared toward homeowners and property managers who need bright, cost-effective lighting for outdoor security, parking areas, or large interior spaces such as workshops and warehouses. The clear finish and high lumen output make it especially useful where long throw and crisp visibility matter.

It is less suited for users who require guaranteed long-term lifespan in continuous-run applications without any downtime, since some customers reported shorter-than-expected life in certain installations. If absolute longevity without variance is essential, consider alternatives with more consistent lifetime feedback.
