Ergomart Gradient Light Filters allow the user to control fluorescent lamps that are too bright in two ways. The sleeve dot matrix pattern graduates from transparent to opaque; the sleeve may be rotated to reduce the light output of fluorescent tube lights. The second major benefit is the user can actually direct light down, left or right. The opaque (black) side can be pointed downward to knock out about 75 percent of the light. We provide two performance levels of this product: STANDARD—simple UV filtering; PREMIUM—Full Spectrum / UV light filtering / glare reducing.

For those who suffer from migraines, these products can reduce the frequency of or even eliminate migraine headaches for some. Both the standard and premium gradient filters reduce the amount of light emitted from a fluorescent lamp and therefore reduce the relative flickering effect in environments where there are secondary non-flickering light sources. The GRX380 has the added benefit of improving the quality of light.

For a detailed explanation of the benefits of this filter and our other offerings, view the Fluorescent Light Filter Information Page.
