LED lighting in the home is becoming more popular due to the energy and money saving benefits it offers over traditional halogen lighting. One of the most common problems that an electrician faces when installing LED’s is enabling them to dim. Resistive dimming has become a standard way of dimming ...

If you dim LED strips that have been wired to a non-dimmable transformer, you’ll damage the transformer. For the different ways you can dim your LED tape, see the notes above. You can use any of these methods with any of our single-colour or white LED tapes. For our RGB LED strip lights, you will require an RGB controller (or controllers).

You can put LED lights on any dimmer but in order to make sure they actually dim, put them on a trailing edge dimmer. Here’s why and what to do.

Dimming saves energy while setting the right light level to improve mood and ambiance. Screw-in compact fluorescent lamps (CFLs) and screw-in light emitting diode bulbs (LEDs) are a great energy-saving alternative to incandescent or halogen light sources; however, dimming them may be difficult.

According to Lutron Electronics, not all LED lights can be dimmed. The packaging must be labeled as "dimmable" and an LED-specific dimmer switch must be used. LED lights do not function in the same manner as incandescent bulbs. Even with the proper LED light and dimmer, it may be impossible to dim the lights as much as with incandescent bulbs.

If you install a non-dimming LED bulb in a circuit with a dimming switch, it will likely operate normally if the dimmer is at its 100% or fully on. Dimming the bulb, will likely cause erratic behavior such as flickering or buzzing and ultimately may cause damage to the bulb. If you have to do this, we suggest keeping the bulb at full power.

Yes, you can. David isn't wrong that if you just had one variable resistance in series with the resistor, adjusting it wouldn't seem very linear in relation to perceived brightness. But if you introduce some resistors in parallel, the picture changes: I tested these values with a red LED and it works pretty great.

Important design considerations. While a linear characteristic between forward voltage/forward current and luminosity exists for LEDs, implementing dimming by analog techniques that vary this voltage/current, although cheap and easy to design, can detrimentally affect the LED’s CCT.
