The Cultiv8 high output compact fluorescent lamp (CFL) is great for use in smaller grow environments and propagation situations.
The screw in lamp base (E40) is the same as used for many HID lamps. This lamp doesn't need a ballast and is plugged directly into a 240 volt wall socket, so the lead needs to have a flat earth pin.
No ballast required
Special coil design to concentrate light output
Very high lumen per watt ratio
Reaches optimum light output in less than three minutes
Wattage and lumen output remains constant during operation
