T5 Shipping Quantity Minimum: Due to increase in damages in transit for single lamp orders, we are requiring any orders that contain T5 lamps to have a qty of at least 2 to help give a bit more overall strength to the lamp grouping.
ATI 39W Blue Plus T5 HO Fluorescent bulb combines the properties of a blue bulb (approximately 460nm) with an actinic bulb (approximately 420nm) producing an intense blue light with high PAR numbers and a light spectrum that encourages both bluing in SPS corals and fluorescence in capable corals. Also helps balance out a washed-out/yellow hued tank. Recommend Use: as a supplement to metal halides or in combination with Aquablue Special, Purple Plus or other full spectrum T5 bulbs. Can also be used for dawn/dusk applications. (Similar to KZ Super Blue.)
