All SunBlaster T5HO Aquarium light bulbs are driven at the optimum temperature, lowering heat production and extending lamp life. The New Edition T5 HO fluorescent Aquarium light bulbs have been re-engineered incorporating a "Cold Chamber" ensuring that the small amount of mercury gas contained is kept at the most efficient operating temperature to produce the maximum light output. SunBlaster T5HO fluorescent replacement bulbs are available in 2' (61cm) 24 watt 6400K, 3' (91cm) 39 watt 6400K and 4' (122cm) 54 watt, 6400K full color spectrum for vegetative growth. High Output 6400K lamps simulate natural sunlight and are ideal for cuttings or vegetative growth. SunBlaster's T5HO lamps produce a light of much greater strength than a conventional tube and as a result, the energy input into the area being lit is much greater and the light penetration is far superior to anything previously available. SunBlaster replacement fluorescent grow lights require a special T5HO Fixture and can not be used in standard fluorescent fixtures. Ideal for Aquariums, greenhouses, general office lighting, Sun Blaster T5HO bulbs are used to simulate average outdoor light conditions, horticulturalists choose the 6400K for the best vegetative growth. For Aquariums the 10,000K bulb is the best.
