SAI™ UNIVERSAL BASIC LIGHT
300W TUNGSTEN HALOGEN LAMP

The SAI™ Universal Basic Light has been developed as part of a system for visualizing complex airflows with neutrally-buoyant bubbles. Like our Modulated Arc Lamp, it provides a beam of uniform intensity to illuminate the trajectories of the helium bubbles. The Universal Basic Light accomplishes this at a much lower cost than the Modulated Arc Lamp if velocity measurements are not required. Also, the smaller, compact design allows for more flexibility and quicker diagnosis of "large-scale" airflow patterns.

This SAI™ Light uses a General Electric ELH 300W tungsten-halogen lamp, generally available from many camera supply stores. Lamp life is rated at 35 hours. Power for the lamp and cooling fan is supplied directly through a grounded, plug-in power cord and a toggle "ON-OFF" switch mounted in the bottom cover, along with a general-purpose power entry module. The projection lens and a unique aperture assembly allow focusing of the light beam on any flow from 24" to infinity. Two apertures are included with the SAI™ Universal Basic Light, an iris and an adjustable slit. The iris provides a circular beam spread that can vary from 2” to 24” in diameter at 6’, while the slit provides a rectangular beam spread from 0” by 22” to 8” by 22” at the same distance.

Overall, the SAI™ Universal Basic Light is quite simple and rugged in design, easy to use and adjust, and cool in operation. The complete assembly with a detachable tripod support weighs only 3.5 lbs. This support consists of a Manfrotto Grip Action Ball Head and a small tripod base, or an ALTERNATE full size tripod with a Panhead.
