Looking for the right bulb can be a bit complicated when you do not know what to search for. A lot of the lights that can be found right now are LED lights. These are known to be more energy-efficient as compared to fluorescent and incandescent lights. There are different color temperatures that are available, two of which are daylight and soft white.
Daylight is the type of light that you need if you want something that is bright. It would imitate having the natural light during day time when you use the light at night. Soft white is known to be not as harsh as compared to daylight. Some would like to use soft white when they would like to have light but not enough to blind them.
