EYE 62541 - 360 Watt - BT37 - Sunlux Ultra Ace - High Pressure Sodium Conversion Lamp - For Use with 400 Watt Metal Halide Ballast - ANSI M59/H33 - Universal Burn - NH360CE/EN - Sunlux Ultra Ace

shipping was fast. seller contacted me twice via email to make sure i was satisifed. the bulb itself fired right up with no defects and reached duty cycle in under 5 minutes. an excellent and affordable way to make my metal halide ballast dual purpose.

Very well packaged. Other bulb vendors should take a lesson here. Fired right up in MH system. Quite pleased so far. I will add a star in 6 months if she still works.
