Edison Heart Filament Bulb — Atmosphere, Versatility, Character
Unlike a standard frosted bulb, this heart filament is designed to be seen. The exposed tungsten wire glows at around 2200K — deeper and warmer than most LED alternatives — making it the right choice for pendant fittings with open or clear glass shades, bedside table lamps, or any space where the bulb itself contributes to the mood. It is not a high-output task light: at 40W it produces a soft, intimate level of brightness suited to ambient rather than functional lighting. If you need to read by it, pair it with a shade that concentrates the beam. It is dimmable with a standard incandescent-compatible dimmer — LED dimmers will not work reliably with this bulb.
This bulb works best in living rooms, bedrooms, dining areas, and hospitality settings where atmosphere matters more than raw lumens. It pairs naturally with industrial-style pendants, cage fittings, and exposed-socket wall lights. For a cohesive look, group two or three across a dining table or along a kitchen island.

Common Questions
Will this bulb fit my existing lamp or pendant?
+
Yes, as long as your fitting has an E27 socket — the standard large screw cap used in most European pendants, floor lamps, and table lamps. If your fitting uses E14 (small screw) or B22 (bayonet), this bulb will not fit. Check the socket type on your current bulb before ordering.
Is the heart filament visible through a shade?
+
The filament is only visible through clear or open glass shades. With an opaque or fabric shade, you will see the warm glow but not the heart shape itself. For the full decorative effect, use this bulb in a cage pendant, a clear glass globe, or an open-socket fitting where the bulb is exposed.
Can I use this bulb with a dimmer switch?
+
Yes — this is a standard incandescent bulb and is compatible with traditional incandescent or leading-edge dimmers. It will not work correctly with LED-specific dimmers, which are increasingly common in newer installations. If you are unsure which type of dimmer you have, check with an electrician before purchasing.
How bright is 40W — is it enough for a bedroom or living room?
+
A 40W incandescent produces roughly 400 lumens — enough for ambient mood lighting but not for reading or task work. It is well suited as a secondary light source in a bedroom or as accent lighting in a living room. If you need more brightness, consider a 60W version or use multiple fittings in the same space.
Is this an energy-efficient bulb?
+
No — this is a traditional incandescent bulb chosen for its aesthetic quality, not energy efficiency. It consumes more power and has a shorter lifespan than LED alternatives. If energy saving is a priority, look for a filament-style LED bulb with an E27 cap, which replicates the warm glow at a fraction of the wattage.
