LIGHTING LINGO: E-H

E14, E27, E40
💡 Meet the Edison screw family: small (E14), standard (E27), and giant (E40). All screw, no hassle.

Edison Screw
💡 Named after the legendary Thomas Edison, this screw-in fitting is as iconic as the light bulb itself.

ES > Edison screw in shorthand. If you see this, think twist-in and power up.

Emergency Lighting
💡 When the power’s out but you still need to find the exit, emergency lighting has your back—powered by rechargeable batteries.

Equivalent Wattage
💡 Old habits die hard. Equivalent wattage helps you compare LED brightness to the incandescent bulbs you grew up with... you know...for those of us born in the '1900s'.

Festoon
💡 Not just fun to say—festoon lights bring the party! Think strings of glowing bulbs, perfect for outdoor celebrations and cozy vibes.

Filament
💡 That fragile wire in incandescent bulbs that glows (and gets ridiculously hot) when powered. LED bulbs mimic the look, minus the heat and drama.

Fluorescent
💡 Long, tube-shaped lights found in kitchens and offices everywhere. Cool, efficient… and quickly being outshined by LEDs.

General Illumination
💡 Basic, everyday lighting. Think ‘the main act,’ while accent lighting plays a supporting role.

GES
💡 Giant Edison screw—because sometimes you just need a bigger twist for extra-bright commercial lamps.

Ghosting
💡 No, it’s not your ex—it’s that annoying faint glow from a bulb after you turn it off. Blame lingering power in the circuit.

GLS
💡 The classic pear-shaped bulb we all know and love. GLS stands for General Lighting Service, but you can just call it the OG.

Halogen
💡 An old-school type of incandescent light with a twist: it’s filled with halogen gas for extra brightness. Most parts of the globe said goodbye to these in mid-00s, but LEDs are a worthy replacement.

Heat Sink
💡 A lifesaver for LEDs, literally. Heat sinks pull away excess heat so your LED can shine bright for years without breaking a sweat.

HID
💡 High-Intensity Discharge lamps—think super bright, super efficient lights used in stadiums, warehouses, and sometimes, your car’s headlights.

High-Power LED
💡 LEDs, but turbocharged! These super bright, energy-efficient lights are ideal for powerful applications like outdoor floodlights.
