I bought some ceiling fans from Beacon Lighting which needed a GX53 led, the ones they were selling cost $34.95 each and are rated at 500 lumens, these are 50 lumens less but should do the job for bedroom area but be aware that they are not as efficient as the more expensive beacon lighting option which is rated at 4.8 watts as opposed to 6 watts, if you live near Ikea they have one cheaper at only $6.99 and its rated at 600 lumens.
A great option if you have a rental.
Bella LED GX53 Globes are an excellent cost-efficient and energy-saving lighting option.
Luce Bella LED Globes consume up to 80% less power compared to incandescent globes and come with 15000 hours of life.
6W, 450lm, 120 degree beam angle
15000 hour led life.
