The Edison bulb has become the default decorative filament form for good reason: the elongated ST64 shape sits well in almost any exposed fixture, the proportions are balanced, and the visible filament creates a quality of glow that no frosted bulb can replicate. It's also the form where CRI quality makes the most visible difference, because the amber glow of the filament is the primary visual element.
Dulora's Edison range covers E27 and B22 bases in Extra Warm 2200K and Warm White 2700K with CRI 90 to 97+ across the range. The higher-CRI models render the amber tones of a 2200K filament with a richness that's visible immediately on installation.
Every dimmable model pairs with a quality LED-rated dimmer. An Edison bulb at 10 to 20 percent on a dimmer produces the deepest, most atmospheric amber glow in the range. For round globe alternatives, see Globe Dimmable. For pendant fixtures, see Pendant Lights.

Edison Bulbs: The Filament Form That Defines a Room's Character
What makes an Edison bulb different from a standard GLS?
The Edison (ST64) is an elongated torpedo shape with a visible filament, designed to be seen. A standard GLS (A60) is a classic pear shape, typically frosted, designed to disappear into a fixture. The Edison is the decorative choice for exposed fixtures; the GLS is the practical choice for shaded ones.
The filament in an Edison bulb produces a warm amber sparkle that changes character as the bulb dims. This is the primary reason to choose it over a standard form.
Which color temperature suits an Edison bulb best?
Extra Warm 2200K is the natural choice for Edison bulbs. The deep amber pairs with the visible filament to produce the warm, atmospheric glow that the form is known for. Warm White 2700K is available for applications where a marginally more neutral tone is preferred without losing the decorative character.
Do Edison bulbs benefit from dimming?
More than almost any other form. An Edison filament at low dimming levels produces a deep amber that transforms the atmosphere of a room. The visible filament structure becomes more pronounced, and the quality of light shifts from functional to atmospheric in a way no other bulb shape replicates as effectively.

Frequently Asked Questions: Edison Bulbs
- What CRI rating do Dulora Edison bulbs have?
- CRI 90 to 97+ across the range, with select premium models reaching CRI 97+ for near-perfect warm-tone rendering.
- Do Dulora Edison bulbs dim smoothly?
- Yes. All dimmable models dim from 1 to 100 percent without flicker or buzz when paired with a compatible LED dimmer.
- What's the difference between an Edison ST64 and a globe G95?
- The Edison ST64 is elongated (torpedo-shaped). The globe G95 is spherical. Both are designed for exposed fixtures. The ST64 suits industrial and vintage aesthetics; the G95 suits contemporary and minimalist interiors.
- Are Dulora Edison bulbs safety certified?
- Yes. All Dulora Edison bulbs are safety certified and covered by a three-year warranty.
