I'm Swain Leung

A lighting enthusiast and home improvement specialist with over 15 years of hands-on experience. What started as fixing my first house's wiring has grown into testing hundreds of bulbs across every room, fixture, and application.

I created lights.wiki because I got tired of buying the wrong bulbs. Walk into any hardware store and you'll see 50 types of LED bulbs with confusing labels — “warm white” on one brand is 3000K, “soft white” on another is also 3000K, but you'd never know it from the packaging.

This site is where I document everything I've learned so you don't have to make the same mistakes.
