Good replacement ...Brighter whiter!

The bulb that burned out was yellowish light and pretty dim. This was an optional replacement but was supposedly brighter and whiter. It is in both circumstances. Good choice!

Great deal and very bright bulbs

Excellent price for 4 bulbs which is half of the local retailer. Very bright and a huge improvement over the previous bulbs. Highly recommended.
