Sunlite 02515 MH175/U/MOG — 175W, 14,000 Lumens
This 175-watt metal halide lamp uses a mogul base (E39) for outdoor fixtures, parking lots, and large commercial luminaires. It delivers about 14,000 lumens at 4000K with an ED28 clear finish. Best for: outdoor flood lighting, sign illumination, and industrial exterior spaces where high output is needed. Caution: longer warm-up and cooling periods may apply in extreme temperatures; verify fixture compatibility with ED28/MOG base.
Sunlite 03656 MH175/U/MOG — Bright, Durable 14k Lumens
Another mogul-base option, this 175W lamp offers 14,000 lumens with a 4000K color temperature and ED28 clear glass. It is well-suited for outdoor security lighting or perimeter illumination where broad, neutral light is desired. Best for: commercial exteriors and parking facilities seeking high efficacy. Better for: fixtures designed specifically for MOG bulbs. Caution: ensure proper ballast compatibility with ED28 type.
Sunlite 03655-SU MH175/U/MED — Medium Base, Clear 14k
This model uses a medium base (E26) and ED17 with 14,000 lumens at 4000K. It offers versatility for street lights and perimeter lighting where a standard socket is preferred. Best for: indoor warehouses or outdoor fixtures using E26 sockets. Choose this if your ballast and fixture are designed for MED base. Caution: slightly shorter bulb length may affect fit in deep fixtures.
Bluex Bulbs 3 Pack MH175/U/MOG — 3-Pack, 14k Lumens
Three-pack mogul-base bulbs delivering about 14,000 lumens at 4000K with ED28. They’re a practical option for multi-fixture installations or replacements in larger exterior lighting systems. Best for: budget-conscious setups needing multiple replacements. Caution: verify fixture tolerance for ED28 mogul bulbs across all sockets in a given installation.
Rossesay MH400/U/MOG — High Output 36,000 Lumens
This single-bulb option delivers a dramatic 36,000 lumens at 4000K with an ED28 mogul base (E39). It is best for very large outdoor spaces or industrial facilities requiring maximal illumination from a single source. Better for: high-visibility areas such as large entrances and loading zones. Limitation: higher output can increase glare and energy use; confirm that the lighting design supports this level of intensity.
Buying Guide
Key considerations when choosing a 175W metal halide bulb:
- Base type and fixture compatibility: Mogul (E39) vs. Medium (E26). Ensure ballast compatibility and socket fit for your fixture.
- Lumens and space size: Higher lumens suit large outdoor areas; smaller rooms may not need maximum output. For exterior areas, plan for even coverage to avoid shadows.
- Color temperature and finish: 4000K (neutral white) is common for workspaces and security lighting; clear glass improves color rendering but can increase glare in some settings.
- Lifespan and maintenance: Estimated life varies by model and use. Consider maintenance cycles for frequent replacements in high-use fixtures.
- Applications and environment: Outdoor, parking, street lighting, and large indoor spaces have different reliability requirements and heat considerations.
- Number of fixtures: If replacing multiple bulbs, buying in a multi-pack can save time and ensure color consistency across fixtures.
- Warm-up and ballast considerations: Metal halide lamps may need a warm-up period after power is applied. Confirm ballast compatibility and whether a slow-start option is available.
