They are Current Usa...
They are the 4 54watt bulbs.
They are super bright, I am so impresed with it I am going to buy the exact model in a 36" version for my 92 corner instead of the halides.
Here is some info off of the web.
Powered by an advanced electronic ballast, the high output T5 lamps are driven to their maximum potential while ensuring long lamp life. The patented circuitry inside each ballast ensures consistent high performance and low energy consumption while meeting FCC standards with EMI protection and low THD. All components are the highest quality available, meeting ISO 9001 standards, and are potted to reduce thermal stress and increase ballast life expectancy. A German parabolic reflector increases light output up to 99%, while an integrated fan cools both ballast and lamps for efficient operation.
Features:
European style high output T5 lamps. Each fixture includes two 460nm Actinic Blue and two Daylight 10,000K SlimPaq high output T5 lamps Performance driven electronic ballast
Moon white lunar light for nocturnal viewing
Parabolic reflector
Fan cooled for maximum efficiency
Energy efficient
Two independent circuits with 6 ft. grounded power cords independently control 10,000K Daylight lamps and 460nm Actinic Blue lamps. Moon White Lunar Lights operate on their own transformer, providing complete control of timing periods.
