The 4,000K color temperature provides a neutral white light ideal for security lighting and industrial facilities. While the packaging shows multiple-packs, the core performance centers on reliable brightness and color consistency, with typical lifetime expectations for commercial-grade HID lamps. This option is valuable for designers planning multiple fixtures with standardized components.
Sylvania 64490 2-Pack (LEDVANCE)
This 2-pack variant from LEDVANCE reflects a consistent 400-watt metal halide performance with a 4,000K color temperature and an ED37 shape. The 2-pack convenience aligns with projects requiring uniform replacements across several fixtures. Expect reliable lumen output and maintained color quality across long operating hours in outdoor or large indoor applications. The product line emphasizes practicality and steady performance for facility managers and lighting designers.
LEDVANCE 400W BT37 Metal Halide HID Light Bulb
The LEDVANCE 400W BT37 lamp offers a high-quality HID solution with a clear finish and a strong lumen output, designed to deliver up to 40,000 lumens depending on ballast configuration. The 3600K-3600K-like spectrum and BT37/EX39 compatibility make it adaptable to a broad range of outdoor and industrial mounting scenarios. With an emphasis on long life and stable performance, this lamp suits facilities that require dependable lighting with relatively fewer replacements.
Vegelumax MH 400W Grow Light
Vegelumax offers a 400W metal halide HID lamp with a high PAR-enhanced blue and violet spectrum, designed for horticultural use. While primarily marketed for indoor plant growth, its 36,000-lumen output and 6000K color temperature deliver bright light suitable for vegetative and flowering stages in controlled environments. The E39 base ensures compatibility with common ballast configurations, and the lamp is engineered for strong lumen maintenance across its rated life in horticultural setups where spectrum optimization matters.

Buying Guide
Key considerations when selecting a 400W metal halide lamp include base compatibility (Mogul E39 vs ED37 vs BT37), ballast compatibility, and the intended environment (outdoor vs indoor). Lumen output is a primary driver for coverage area and fixture spacing, with higher lumens enabling longer reaches and brighter illumination. Color temperature, typically around 4000K or 3600K, influences perceived brightness and contrast; higher Kelvin values yield cooler, crisper light. Lifespan and maintenance intervals affect total cost of ownership; lamps with longer rated life reduce replacement frequency in hard-to-access fixtures. Reliability and supplier support should guide brand choice for critical infrastructure projects. Consider multi-pack options to simplify bulk replacements and ensure color and performance consistency across all fixtures. For horticultural applications, spectrum composition (blue/violet enhancement) can be important, as with Vegelumax lamps. Finally, verify packaging, shipping conditions, and warranty terms to protect long-term investment in outdoor or industrial lighting.
