Load is measured in Watts and is usually printed on the bulb itself. If you have multiple bulbs on the same circuit, you need to add them together to work out the total load.
Too little load means that the bulbs may not turn on or off properly. Too much load means that you could damage or destroy the light fitting, so it is important to get this right.
Incandescent load (includes halogens and lower energy halogens)
Generation 1 1 & 2 gang dimmers are rated at 250W maximum of incandescent Load, and 3 & 4 gang dimmers are rated at 210W maximum. Generation 2 1 gang dimmers are rated at 350W incandescent load and 2,3 & 4 gangs at 250W.
LED loads differs from incandescent load (and will be significantly lower than the max incandescent load). Each LED lamp differs in terms of its operational behavior and subsequent compatibility; therefore loading limits vary between different lamps. We strongly recommend that you check Lightwave compatibility charts for Generation 1 and 2 dimmers for the maximum and minimum recommended loading limits and lamp numbers for each lamp type.
Please note Due to the sheer volume and variety of lamps on the market, there is no possibility for every lamp to be tested, so not all LEDs in the market are compatible with LightwaveRF Dimmers.
