The best option is fluorescent lighting
Firstly, considering the character of the room, the lights should have a higher IP coverage (learn more about IP ratings by clicking here). The IP value should be at least 44, meaning the light is protected from water splashing in all directions, as well as from penetration of foreign solid objects with diameter of 1 mm or larger. For lights that are also dust-proof, look for an IP rating which begins with the number 5 or 6. People often work in their garage and carry heavy objects, so it's useful if the lights have some shielding.
In our experience, fluorescent lights are the most suitable solution for a garage. They diffuse lots of light into the whole room, and they have low energy consumption. We recommend buying fluorescent lighting with an electronic ballast which makes the light switch on immediately and prevents the initial unpleasant glimmer. This way you won't have to wait for the lights to light up fully and you can drive in right away.
Even if you have a small garage, we don't recommend buying just a single light. If you have a bigger garage containing also a workshop, you should definitely get multiple light sources. Speaking of workshop illumination, don't forget to get a light for your work desk. Again, you can use a fluorescent light and place it in a way that it doesn't cast shadows on your work. For particularly detail work, it's good to use a desk lamp as an additional source of light.
Practical lights with sensors
A good choice for lighting up space in front of the garage is lighting with a sensor. These lights have a built-in motion sensor that turns the light on automatically whenever it detects movement within their range. And since they are truly practical, they switch off by themselves after a while. Therefore, the lights are on only when needed, so you save on your energy bills. Lights with sensors are also useful for the garage interior. That way, you won't have to worry ever again whether you forgot to switch the light off.
