GLS-ledlampen

The GLS is the bulb doing most of the heavy lifting in a typical home. It goes into the living room ceiling fixture, the floor lamp by the armchair, the hallway fitting that greets you at the door. It's also the bulb most people buy without a second thought, which is a missed opportunity: CRI 90 to 97+ in a GLS bulb transforms the character of a room for roughly the price of a cup of coffee.

Dulora's dimmable GLS range covers E27 and B22 bases in clear and frosted glass across Extra Warm 2200K, Warm White 2700K, and Soft White 3000K. Clear glass shows the filament for exposed fixtures; frosted glass diffuses the output for shaded fixtures.

Every dimmable model connects directly to standard household power and pairs cleanly with a quality LED-rated dimmer, dimming from 1 to 100 percent without flicker at any level. For the candle range, see Candle Bulbs. For round globe forms, see Globe Dimmable.

Dimmable GLS Bulbs: The Practical Upgrade That Changes How a Room Feels

E27 or B22: which base does my fixture use?

E27 (standard screw base) and B22 (standard bayonet cap) are the two most common GLS bases. B22 uses a push-and-twist connection, while E27 screws in. Remove the existing bulb and check the base before ordering, since the two aren't interchangeable.

Clear or frosted: which glass finish should I choose?

Clear glass shows the LED filament through the envelope, producing a sparkle quality suited to exposed fixtures where the bulb is visible: open pendants, cage lights, and decorative fittings. Frosted glass diffuses the light into a softer, more even output with no visible filament, the practical choice for shaded fixtures.

If the bulb is hidden behind a shade, frosted is almost always the better option. If the bulb is visible, clear adds visual character.

Which color temperature works best for a GLS bulb?

Warm White 2700K is the most versatile choice for most homes: warm enough to feel inviting, clear enough for general use throughout the day. Extra Warm 2200K suits living rooms and bedrooms used mainly in the evening, where a deeper amber creates a more atmospheric feel. Soft White 3000K is marginally crisper, working well in kitchens and utility spaces.

Why does dimmer type matter for LED bulbs?

LED bulbs draw far less power than the incandescent bulbs older dimmers were designed for. A dimmer rated for high-wattage incandescent loads may buzz, flicker, or fail to dim properly with a low-wattage LED. Dimmers specifically rated for LED loads solve this in almost every case. See Dimmer Switches.
