The GE 400W SON-T E40 Grow Lamp (93142331) is a compact high-pressure sodium (HPS) solution for growers seeking an ideal balance between power, efficiency, and affordability.
Designed with a 2100K warm light spectrum, this lamp drives vigorous bloom development, especially in photoperiod crops. With a PPF of 700 µmol/s and 55,000+ lumens, it's perfect for mid-sized hydroponic operations, grow tents, or supplemental greenhouse lighting. Backed by GE’s proven durability, it operates universally and lasts up to 18,000 hours with minimal loss in PAR intensity.
This 400W HPS lamp from GE offers distinct advantages over equivalent LEDs:
Better Penetration for Dense Canopies – Reaches lower branches, improving total yield.
Consistent Spectrum – No degradation in spectral output like many LED chips.
Proven ROI – Trusted in commercial grow setups for years with predictable results.
More Affordable Start-Up Cost – Great for growers upgrading from CFLs or adding to LED systems.
Ideal applications for the 400W SON-T E40 lamp include:
🌿 Bloom stage in medium grow tents or side lighting for large spaces
🏢 Compact commercial greenhouse rows
🌱 Supplementary flowering light for vertical systems
🌾 Veg-to-bloom transition lighting in staged hydroponic operations
Perfect for: Tomatoes, Peppers, Cannabis, Chillies, Strawberries, Cucumbers, and other photoperiod-sensitive crops.
