LED Lamp Testing

LED quality might have improved in recent years, but choosing a good lamp is still more difficult than it should be. Demand for cheap goods has resulted in an influx of poor quality LEDs into the market, with astronomical voltages spikes and unacceptable levels of flickering. Without quality controls to prevent this, and a large number of lighting companies importing rather than manufacturing products, these below-par lamps can end up on the shelf stamped with a trusted household name.

The Society of Lighting and Lux Review have both recently reported that LEDs still present a great deal of uncertainty for installers, and that’s before you introduce a dimmer to the circuit. Here’s how Zano can help.

With over 60 approved dimmable lamps there’s plenty of choice. We only release the most up-to-date info, so give us a call and we’ll help you get the right tools for your job. We’re also more than happy to test your lamps for free. Call 0330 058 0010 to speak with our team today.

We rigorously test a wide range of lamps to make sure that they really do perform well. The difference between the wattage stated on the packaging and the actual power consumption of the lamp can be staggering. That’s why we test not only for smooth consistent light and fantastic range, but also for each lamp’s true wattage. We award a Gold, Silver or Bronze rating based on performance, so you can see just how compatible a lamp is before installing. Some lamps don’t even pass simple mains testing without flickering, but those that do are tested in varying numbers with a variety of dimmers. Our testing reveals current spikes and flicker, as well as an accurate power profile for true wattage. We know our dimmers are fantastic, and now we can help you choose great quality lamps too.


Means the lamps will dim down to or below 5% of their usual brightness and up to 90% or above on the higher end of the scale.

Means that the lamps will meet this requirement at one end of the scale, top or bottom but fall just short at the other end.

Means that the lamps still dim without flicker and have a wide range but fall just short of Zano’s ideal range at both ends of the scale.
