Direct replacement for what was needed.
Your review: These 2W LED bulbs replaced the halogen 20W bulbs we were using in elevators that have lights on 24/7. The LED's are cooler, brighter and last much longer, reducing not just electrical expenses, but the labor rate expense as well. The 20W bulbs blew out every 3 to 4 months, while the LED's installed over a year ago are still lit.
Pros: Lasts longer, shines brighter, easy replacement of original bulbs, Saves on expense on multiple levels.
Cons: I did have one out of 16 bulbs ordered fail. However all the other bulbs are still in operation for almost two years now.
