Our premium 685 tube light filters and 885 flat sheets are placed over standard fluorescent lights to produce the same full spectrum effect (a balance of red, orange, yellow, green, blue, indigo, and violet found in sunlight). This will not only improve color rendering but also reduce glare. In addition, these filters cut virtually all of UVA and UVB radiation below 380 nanometers.

For those who already understand the benefits of full spectrum lighting, our 685 light filters bring many advantages over expensive full spectrum bulbs. Bulbs, which typically only remain full spectrum for 5,000 hours (or approximately a year), are costly to replace and don't offer any UV protection. In fact, most of those full spectrum bulbs have increased UV when compared to a standard cool white lamp.

Although the filters decrease the overall light output, visual acuity is improved. The filter creates scotopically enhanced light by lowering certain wavelengths so that the critical blue-green component is more prominent. Despite less light, with the enhanced blue-green spectrum, the pupil is made smaller, allowing the iris to operate “more efficiently” and therefore allowing less confusing rays into the back of the retinal surface. This causes the depth of field to increase and visual acuity is improved. This is especially useful for environments such as libraries, museums, the food industry and textile industry, where UV and visible light rays may be damaging, but visual acuity is still an absolute requirement.

Numerous studies have proven the benefits of full-spectrum and natural daylighting. It can help those suffering from CVS—computer vision syndrome, SAD—seasonal affective disorder, and lupus erythematosus. Full-spectrum lighting improves performance in academic settings and students had more positive moods, developed fewer dental cavities, had better attendance, and better growth and development. They also suffered from less hyperactivity.  This light filtering system effectively transitions your fluorescent lit setting towards a more daylight like environment

We suggest using the sleeves for fixtures with three or less 4' lamps and flat sheets for 4 lamp 2' x 4' fixtures.  More detailed information regarding these filters is available.

NOTE: The Ergomart T5 Light Filter is suitable for Standard T5 lamps only.  End caps must be used or melting will occur.  This product is NOT designed for use with High Output T5 Lamps.

MORE DETAILS, FEATURES, AND FACTS ABOUT THE F685 FLUORESCENT LIGHT FILTERS

  • The Color Rendition Index (CRI) is a way scientists determine the light quality in terms of color accuracy based on the color temperature of the light source. Generally speaking the higher the rating, the better the light. 
  • The 685 filter is 20x more effective in absorbing UV rays when compared to a standard clear prismatic filter
  • Makes light appear closer to perfect full spectrum light, daylight, so things appear the same both indoors & out
  • Eases the effects of computer vision syndrome including blurred vision, neck pain, and dry, irritated eyes
  • You can get the same great features of the F685 from our F885 premium flat sheet filters
  • Up to 40% of fading is caused by UV rays, which can be greatly reduced by these filters
  • Balances the blue-green portion of the spectrum creating a scotopically enhanced light
  • Reduces glare which can relieve eyestrain, headaches, and even general fatigue
  • Natural daylight used in classrooms increased test scores by an average of 21%
  • Helps lupus sufferers by absorbing the UV rays that can cause flare-ups
  • Natural daylight used in retail increased sales by up to 40%
