We installed 4 of these in our garage (about 80 square meters). We were specifically looking for a high lumen light with a 4000K color temperature to match our existing lighting. There were very few options, but we're glad we found them. These bulbs are incredibly bright, especially with the white walls and ceiling in our garage. The picture does not convey these bulbs. The only downside to these lamps is that with three "wings" the light appears more focused with hot spots compared to a traditional lamp. We used to have 300w CFL bulbs in the garage which gave a much more even light. Unfortunately, they are no longer made, but they use a lot more energy than these.
