Which lamps (bulbs) should I use?
When installing any light fitting, especially electronic dimmers, it is very important to use suitably compatible bulbs (also referred to as ‘lamps’). Compatibility is important because not all bulbs work in the same way, and not all bulbs are dimmable. It is also vital to use bulbs that do not exceed the maximum or minimum loads recommended for the fitting. For non-dimmable and high load options and in-line relay can be used in place of a dimmer.
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. Load limits are specified for each LightwaveRF product on the box and in the manual.
IMPORTANT: LED loads differ from other lamps such as halogens or CFLs. The maximum recommended load on a LightwaveRF dimmer is 250W; however, we do not recommend exceeding 80W for LED bulbs.

Incandescents, CFLs & halogens
Traditional incandescent lightbulbs, halogens, and lower energy halogens are all fine to use with LightwaveRF lighting products as long as they are within the total minimum and maximum loads. CFL bulbs are generally not dimmable, so are not recommended, and CFL tubes could cause damage to the dimmers so should not be used.

LED lighting is quickly becoming a popular solution for people looking to reduce their energy consumption. However, there are not many standards in the market, and many LED lights can have difficulty when dimming. LightwaveRF dimmer switches are designed to work with LEDs if the LEDs are dimmable, but even then, there are some varieties that will have trouble dimming and may flicker. This may be resolved by increasing the total load (adding more bulbs), but not always. To ensure successful dimming, a good solution is to use pre-tested bulbs recommended on our compatibility chart.

Low voltage & LED strip
Low voltage trip lighting can be used with a LightwaveRF dimmer as long as it is within the loading requirements and is used with a suitable dimmable transformer. Not all transformers are compatible, so please check the technical section below for advice on which transformers to use.
