It features a Mogul Screw (E39) base and an ED18 shape, well-suited for enclosed fixtures and energy-conscious projects. The bulb is crafted to meet stringent environmental standards and provides solid performance in outdoor and industrial settings, including street and parking environments.
iPower 400W HPS Grow Light Bulb
iPower’s 400W HPS bulb is designed for professional hydroponic cultivation with a CCT of 2100K and enhanced red/orange spectrum. It delivers about 55,000 lumens and uses an E39 base compatible with electronic and magnetic ballasts. The design emphasizes high PAR for flowering and fruiting, with a focus on maintaining lumen output over time to support sustained growth cycles.
Sylvania 400W Plantastar High Pressure Sodium
Sylvania’s Plantastar line offers 50,000 lumens at 2100K and uses an E39 base with a clear glass envelope. It’s positioned for horticultural applications across growth stages, including vegetative and flowering cycles in greenhouses or controlled environments. The product emphasizes a reliable life span and consistent performance to support steady plant development while delivering sufficient intensity for wide-area plant coverage.
GRUOTVSZAK HPS 400W Grow Light Bulb (2-Pack)
This two-pack provides 400W HPS bulbs with high lumen output designed for optimized flowering and bloom cycles. They feature E39 bases and broad compatibility with standard horticulture and industrial lighting fixtures. The bulbs are intended to deliver robust intensity for grow environments, with a focus on reliable operation in long-term applications.
Buying Guide: Key Purchase Considerations
- Lumens and spectrum: Most 400W HPS bulbs deliver around 50,000–55,000 lumens with a color temperature near 2100K. Choose higher lumen outputs for larger areas and 2100K or comparable warmer spectra for flowering and exterior lighting where warm tones are preferred.
- Base compatibility: Ensure the mogul base (E39) and ED18 shape match your ballast and fixture. ANSI codes like S51 or S54 indicate compatibility, so verify ballast compatibility before purchase.
- Application environment: Outdoor, street, or industrial settings require enclosures and weather resistance considerations. Some bulbs are optimized for enclosed fixtures or specific ballast types; verify installation requirements.
- Life expectancy: Lifespans around 24,000–24,000+ hours are common. Longer life reduces replacement frequency but check lumen depreciation over time to gauge sustained brightness.
- Electrical compatibility: Some bulbs support both electronic and magnetic ballasts; confirm your ballast type to avoid performance issues or reduced lifespans.
- Hydroponic versus outdoor use: Bulbs marketed for horticulture emphasize PAR output and spectrum tuned for blooming and vegetative stages. For general outdoor lighting, focus on brightness and efficiency rather than spectrum optimization.
- Environmental and compliance notes: Look for bulbs that meet local energy and environmental standards and avoid materials or practices that conflict with regulations in your area.
