Perfect light for waking up when it's still dark outside.
These light are super bright and perfect for a kitchen or any room where you want bright light. I installed them in my kitchen because that is where I drink my morning caffeine and they help me get going when it's still dark outside. I would not like the daylight ones in any room where you just want to hang out and relax because they are so bright.

    My husband and I live in an apartment and our kitchen light started to flicker. We decided that we needed a replacement for this light. We bought a pack of two a few days ago. These lights are very easy to assemble and replace. They're also lightweight but very bright. There were several different packs of product in each individual packaging at the store. Since we just needed two, we bought the two pack one. I am very pleased with these lights because they were easy to find in the store. The light itself is white and it shines like a bright milky white color, which brightens my whole kitchen while I am cooking or baking. The price is quite decent too. Even a newbie can replace these lights, that's how easy it is to use them. The packaging was easy to open too. These lights are so much better than those yellow lights that you see in/around houses. I'd definitely recommend these to everyone.
