Home / Identifying light bulbs and dimming types

The Treatlife dimmer switch is compatible with most residential light bulb types, including LED, incandescent, CFL, and fluorescent bulbs.


LED

How to identify

Most residential LED light bulbs have a typical light bulb shape but are usually made with a plastic shell instead of glass, and only a portion of the bulb is translucent. Also you should confirm there is an "LED" or "LED LAMP" marking on the bulb.

Dimming type

Most residential LED light bulbs are dimmable, but some are not. In addition, the amount or “dimming range”the switch can dim also varies based on the light bulb used. For the best experience, use LEDs that have the highest range of dimming. and while non-dimmable LED bulbs are supported, they aren’t recommended for the best-layered lighting experience.

Since dimmable LED bulbs have a variety of dimming ranges, Treatlife set the minimum brightness adjustment function.
This setting can be changed in the Smart Life App and can help resolve any dimming or flickering issues you may encounter.
WARNING: To identify a non-dimmable LED bulb, look for a label on the bulb that states: Do not use with the dimmer.

Incandescent
How to identify

Incandescent bulbs have been the most common type of residential light bulb until more energy-efficient bulbs like CFL or LEDs have gained in popularity. They usually have a translucent or transparent glass casing, and you can see the internal filament directly through the casing.

Dimming type

Incandescent bulbs have a very wide range of dimming. It provides a great range when creating layered lighting, from very bright scenes to beautiful lighting when darkened.

Halogen

How to identify

Halogen light bulbs typically look very similar to an incandescent bulb, they have a similar shape and glass casing. Look for the “HALOGEN” mark on the bulb or package.

Dimming type

Halogen bulbs are very similar to incandescent bulbs but are more energy efficient. Like incandescent bulbs, halogen bulbs have the widest range of dimming and glow beautifully when dimmed.

CFL (Compact Fluorescent)
How to identify

CFL light bulbs fit in the same space as a typical residential light bulb, but usually have a spiral or U-shaped glass tube that is illuminated.

Dimming type

Most CFL bulbs are not dimmable, and those dimmable CFL bulbs typically have a narrower dimming range than LED or incandescent bulbs.

Treatlife set the minimum brightness adjustment function.
This setting can be changed in the Smart Life App and can help resolve any dimming or flickering issues you may encounter.

Warning: To identify a non-dimmable CFL light bulb, look for a label on the bulb stating the following: NOT FOR USE WITH DIMMERS.

Note: CFLs typically take time to “warm up” to their full brightness.
