Testing Process Ratings Explained

Rating Types

Rating Explanation
Excellent

An LED rating as excellent will have no or only very minor imperfections in visual performance. It will dim to 1% or less of maximum output and will not have excessive peak currents meaning a decent number of fittings can be used per circuit.

Very Good

A very good rating is given to an LED that has only minor flaws in its visual performance. These might include a slight shimmer while fading or a slightly uneven profile.

Good

A good LED will have either a single significant flaw (big step in output range, very noticeable flicker when fading) or several more minor flaws in visual performance. Sometimes an LED with visual performance that could be rated as "Very Good" may be downgraded due to a high peaks meaning only a small number of fittings can be used per circuit.

Neutral

Neutral rated LEDs will have several significant flaws in there visual performance or may perform well above a certain dimmed level but have very noticeable bottom end flicker. It may be necessary to edit profiles for a neutral rated LED to bring it up to an acceptable standard.

Not Recommended

This lamp or fittings has sufficient flaws that it would not be acceptable to most users.
