This is good news for a few reasons. Figuring out exactly which one to buy can be a pain: Incandescent bulbs are cheap, but burn out easily. CFL bulbs, the weird curly things that’ve become popular in recent years, are brighter and last longer. However, they take long to warm up and use poisonous chemicals like mercury to generate light. LEDs last the longest and use the least amount of energy, but they’re also the most expensive. Now, thanks to General Electric, it will be a little easier to sort through the options.
