The ENERGY STAR Lamp Specification requires lamps that are labeled as “dimmable” to meet a set of dimming performance requirements. The ENERGY STAR specification requires that when operated with a dimmer/control, the lamps full light output should be no less than 80% of the lighting output when operated without a dimmer/control; and the minimum light output when operated with a dimmer shall be no more than 20% of the maximum light output when operated with a dimmer/control. The Voluntary California Quality LED Lamp Specification requires that all tested lamps must meet the stated dimmability requirement. The Voluntary California Quality LED Lamp Specification dimmability requirement states that lamps must operate without visible flicker or audible noise between 100% and 10% initial luminous output. Table summarizes the dimmability requirements of the ENERGY STAR Lamp Specification and the Voluntary California Quality LED Lamp Specification.

The ENERGY STAR Lamp Specification includes flicker as a sub-requirement to the dimming lamps section of the specification. The ENERGY STAR specification requires that lamps marked as dimmable report periodic frequency, percent flicker, and flicker index. No maximum limits are set by the ENERGY STAR Specification. The Voluntary California Quality LED Lamp Specification requires that all lamps are flicker free from 10-100 percent luminous output. Table 27 summarizes the Flicker requirements of the ENERGY STAR Lamp Specification and the Voluntary California Quality LED Lamp Specification.

Both the ENERGY STAR Lamps Specification and the Voluntary California Quality LED Lamp Specification require that the lamps not produce audible noise over 24 decibels (dBA) when measured at 1 meter or less from the lamp. The ENERGY STAR Specification includes audible noise as a subset of the dimming requirement, and states that 80% of lamp/dimmer combinations must meet the requirement. The Voluntary California Specification requires all lamps meet the audible noise requirement of noise free operation from 10-100 percent power. Table 28 summarizes the audible noise requirement for the ENERGY STAR Lamp Specification and the Voluntary California Quality LED Lamp Specification.
