Bought these 3 packs to fit one in my new air vent. After installation I turned on the light and lo and behold - brighter than a 60W bulb and only runs on 7W! I decided to stick with the other 2 bulbs as a backup, but I liked the bulb's performance so much that I installed the remaining 2 bulbs in my fridge and freezer. If these led bulbs last as long as expected I will use them in closets, garage and attic. The light provided is phenomenal.
