SoLux: Daylight Bulb


SoLux is a patented light source that provides an unparalleled replication of  the daylight spectrum. SoLux has been tested, approved, and recommended by the worlds most exacting color experts in various disciplines ranging from museum lighting, light therapy, photography, digital color proofing, automotive paint finishing, and machine vision. SoLux is currently available as a 50 watt and 35 watt, 12 volt lamp in a standard MR-16 format. The base for MR-16 light sources consist of two pins that plug into a female socket.  SoLux emits daylight at correlated color temperatures of  3500K(± 200K), 4100K(± 200K), and 4700K (± 200K). The 3500K, 4100K,and 4700K SoLux bulbs have a lifetime of 4000 hours, unsurpassed color rendering indices, and ultra-low ultraviolet and infrared radiation. They are available in two wattages, 35 and 50 watts, and four beamspreads 10°, 17°, 24°, & 36°. SoLux also comes in a color temperature of 5000K(D50) (± 200K). The 5000K is available in 35Watts and 36 degrees. Click here if you would like definitions of terms used above.

An Independent evaluation of SoLux has recently been published. The results showed SoLux produced a daylight spectrum far superior to any competing daylight source.  Below are graphs summarizing the findings.  The black line is D50 and the green line closely following it is SoLux.  The CRI values average 98.3.  For a copy of the report go to BabelColor

What our customers are saying...

""Your Solux lamps have made a significant difference for many people working in the area of critical colour management, especially in relation to metamerism with pigment printer inksets. We use a GretagMacbeth Spectroscan with Profile maker 4.1.1 software and include a custom SoLux lamp viewing light source spectrum in our profile calculations. This produces greater accuracy than with any other continuous spectrum viewing light source I have tested. For example our average LabD50 Delta E profile accuracy is typically better than 0.50, which is quite amazing. Thanks." "
