48" (F54) T5 6000K (54 watt) HO Daylight Bulb

T-5 bulbs are the latest phenomenon in high intensity lighting that sometimes rival even metal halides. These work with the IceCap 440 and 660 series ballast and no modification to the ballast is required.

 

The "GIESEMANN LICHTTECHINIK" brand "German made" bulbs are the ONLY bulbs that we trust that the Kelvin rating is correct and and as advertised.  You can buy cheaper bulbs, but we have found that they are NOT the kelvin rating as advertised by the manufacturer.

Please note that you must purchase this shipping container when ordering bulbs;
