F574 T8 and T12 Sleeves

• Change the ratios of the light spectra emitted by cool white fluorescents to improve the spectral balance to more closely resemble daylight
• Reduce reflective and veiling glare by partially polarizing the light waves
• Eliminate virtually all UV-A UV-B and UV-C radiation below 380 nanometers
• Optimized for older, halophosphor fluorescent lamps

• Easy to use and sized to fit 2 x 4 foot fixtures
• Save money by using cheaper fluorescents with our filters instead of full-spectrum bulbs
• Research documents the benefits of improved spectrum lighting
• Many suffering from CVS show relief with our spectrum light filters
