Encourage tomato plants to fruit indoors with a high pressure sodium lamp. By emitting light from the red-orange region of the spectrum, this sort of HID lighting simulates the sun’s light in fall. Plants under a high pressure sodium light think its time to finish their growing cycles so they make flowers and fruit.

This 1000-watt high pressure sodium lighting kit includes:

• 1000-Watt Sunleaves Pulsar Ballast—This Sunleaves Pulsar Ballast is among the "coolest" around because the vented housing design cools operation and prolongs unit lifespan. Ballast can be fitted with an active exhaust system using the Sunleaves Pulsar Ballast Flange Kit. Near-silent and simple to use, ballast comes completely pre-wired, plugs into any grounded, 120-volt home outlet and includes a five-year warranty.
• Sunleaves Sunspot Reflector— The Sunspot Reflector's strong, formed heavy duty housing features a durable, enamel-coated finish and specular aluminum interior. The unit accommodates a safety lens as well as flanges for easy ventilation.
• 1000-Watt U Hortilux—The Hortilux is our best 1000-watt HPS bulb for spectral and lumen output. Strong yellow-orange-red HPS light for fruiting and flowering is supplemented with an increase in the blue spectrum for healthy, compact vegetative growth. Can be used in base-up or horizontal position.
• Sunleaves Universal Cordset—6 Kv pulse rated socket and cord.
