Dimming options - T8 120cm 20W LED Tube 

NOTICE: This is a bundle sell that includes a Dimmable tube + LED driver. If you are not sure which dimming method to use, please contact us technical support +442477675575

The T5 and T8 tubes can be controlled smoothly without flickering from 0% to 100%. The following widely used dimming methods are offered by Voltacon:

- AC Triac Dimming (Mains Dimming with Trailing Edge dimmer switches)

This is the simplest and the most common method, it requires an external driver and no extra wiring. The mains dimmer (live and neutral wires) switch controls the input voltage to the LED driver

Compatible Dimmer switches: Varilight, Lutron, Osram.

- Meanwell & GLACIAL 3 in 1 dimming: 1-10V, Resistive potentimeter

External dimming signal is required with 1x pair of cables. The dimmable driver will power up and control 1 or 2 tubes according to the power rating. The control signal (1-10V) is a pair of cables with positive (blue) and negative (white) polarity.

Compatible Dimmer switches: Varilight, Lutron, Osram, other 1-10V dimmer switches or resistive potentiometers

- DALI Control (Digital Addressable Lighting Interface)

An external LED driver with multi stage constant current output is required. The output current level can be adjusted by controlling the DIP switches. The MEANWELL range of DALI drivers are available in 25w 40w and 60w. These are digital controlled models with DALI interface and push dimming function. DALI technology offers high precision dimming and diagnosis of the state of the LED lamps.

T8 LED tubes dimmable with Standard Mains Dimmers - 120CM 20Watt

Our dimmable tubes are very easy to use and come wiith an external dimmable driver which is quite small and compact only 85 x 54 x 32.5mm.

The VOLTACON LED tubes are dimmed very smoothly from 10% up to 100% without any flicker.  The brightness can be adjusted with standard dimmer switches such as the well know VARILIGHT. The T8 and T5 LED VOLTACON LED tubes are compatible with all three of the main LED dimmer series: 

V-Pro (LED Dimmer up to 100W or 10 lamps)

V-Com (LED Dimmer for larger loads)

Eclique2 (Remote Control Dimmer)

All the dimmer switches are available from our online website.  The VOLTACON led tubes are compatible with a wide range of LED dimmers in the market but we listed only one reputable maker of dimmers in our website.
You can contact our technical support for further information. 

All our tubes come with Frosted covers. Unlike Clear covers, Frosted covers disperse uniform light, making them qualitatively superior to the Clear covers. If for any reason you require Clear covers, please contact us
