The ECO Punch Plus runs so cool you can touch it with bare hands and save up to 90% of your A/C and energy usage. Optical efficiency allows for a single light source and eliminates multiple shadows. Special effects include variable lightning and strobe, which have made lightning strikes inefficient. Quick change lenses vary between spot and flood (and still keep an even field with such high output!) ECO Punch Plus is actually brighter than a 2500W HMI and generates far less heat to worry about. Think about the energy and safety factor and how friendly these lights are to the talent and crew.
