I use LEDs in the gas station lights in front of the garage. A large light above the person's door with 200w equivalent and two smaller lights above the elevator door with these two 100w equivalent bulbs matching one light. When I first opened the package I thought "they will never work" but I decided that since their characteristics are what I need in terms of light (brightness, power etc.) their price is worth trying. These tiny bulbs put out an insane amount of light, just like Acorn's LED bulbs, which are 5 times larger. Don't let their size fool you, they're just as bright and great value compared to other LED offerings.
