In stock! Introducing the Dazor Saturn LED Spot!

Dazor Saturn LED Spot(A special thank you to Dazor for guest-blogging the content below!)

Dazor’s new Saturn LED Spot is the latest generation in high-quality, energy-efficient lighting designed for years of use with the most demanding visual tasks in a variety of production environments.   Many LED fixture manufacturers claim their light will last for the full LED life published by the chip manufacturer.  In reality they rarely do.  The reason is most fixture manufacturers do not have the expertise – or they take shortcuts in materials or production – to design the required combination of electrical, thermal, mechanical and optical system components.

In comparison, the Saturn LED spot is designed with advanced LED chip technology alongside Dazor’s engineering proficiency in optoelectronics and thermal management.  What does this mean to a user?  If a 75-watt incandescent or halogen fixture is replaced with a Saturn LED fixture, the initial fixture investment will be recovered in a year.  And considering the annual savings in energy costs, bulb replacements and related maintenance, during the 15+ year life of the fixture the return on investment is earned many times over.

A common measurement of a light source is the lumen.  Lumen, or luminous flux, is the total amount of visible light emitted from a source.  Understanding this definition is crucial when comparing different light source technologies.  As an example, a 75-watt incandescent bulb produces 1200 lumens.  That sounds like a lot of energy and a lot of light, and it is.  However, light from a filament-based source is emitted in an omni-directional pattern; that is, equally in all directions.  And when installed into a fixture, at best only 45% of the light hits the intended work surface.  This is an extremely inefficient method for delivering light where the user needs it. By contrast, an optically designed LED light source directs the light precisely where it’s needed and requires a fraction of the energy to do so.

The amount of light on a work surface is measured in the footcandle or lux.  1 footcandle (fc) = 10.764 lux (lx), with lux being the metric equivalent of footcandle.  At a 12” distance, a 75-watt screw-in bulb mounted in a typical incandescent housing produces about 300fc of visible light intensity on a work surface, while the 5.5-watt Saturn LED fixture produces 2500fc using a 16ᴼ optical beam spread.  That’s less than 1/10 the energy required to produce eight times the light intensity.

Another quantitative measurement of lighting is efficacy, which is the amount of light produced by the fixture compared to the amount of power consumed to produce it.  The Saturn LED fixture produces 600 lumens by consuming total fixture power of 5.5 watts, resulting in 109 lumens per watt.  An incandescent bulb produces 1200 lumens by consuming 75 watts, resulting in a luminous efficacy of 16 lumens per watt.  And 90% of the total radiant energy produced by an incandescent bulb is heat, not light.   So an incandescent bulb is a lot better as a heat source than it is as a source of light.

Using less energy, saving money, and even being environmentally friendly are all quantifiable advantages of the Saturn LED light over incandescent, halogen and fluorescent light sources.  But what about quality of the light?  All the numerical benefits don’t mean a thing if a user doesn’t like the lighting.  In its infancy as a new and alternative light source, LED manufacturers rushed to sell LEDs into the marketplace and fixture manufacturers were just as happy to install them into poorly designed fixtures.  The result was lighting fixtures which housed LED technology that produced unappealing light output and performance that didn’t live up to expectations.  That’s still the case today when shortcuts are taken.  However, dramatic improvements during recent years have been made in LED chip designs and manufacturing control processes specifically focusing on light quality.  Pleasing, uniform, color-accurate illumination that meets performance expectation is exactly what’s designed into the Saturn LED light.

In addition, the Saturn LED light has a precision-smooth on/off dimming control machined into the aluminum housing and a choice of optical beam spreads to suit user applications.  The fixture is available on a gooseneck or counterbalanced floating arm and can be mounted to horizontal, sloped or vertical surfaces, a rolling or pedestal floor stand, or onto any end-user equipment.
