The ikan "L" Series of Fluorescent Lights feature two columns of 55 watt bulbs. They range from 2 bulbs to a whopping 16 bulbs! The longer "L" series lights are perfect for green screens. The ikan lights stand above from the competition with included bulbs and barndoor intensifiers. Most other companies make you pay extra for those items.
They all also feature built-in ballasts and built- in push-button dimmers. All models are also available with DMX control. Those models have a "D" after the part number. DMX control allows you to control up to 512 lights from one control box. All in all the ikan fluorescent lights are the best bang for the buck. Period.
