I thought I would provide you a great service by recommending products that I use and have tested over time, and, provide a handy link where you can purchase the items if you wish.
I have purchased the compact fluorescent light bulbs you see at the link below and have had good luck with them. The price seems to be very comparable to other stores and even less expensive than some. The bonus is you don’t have to leave your home to get the compact fluorescent light bulbs.
These light bulbs come 4 in a pack, are rated at giving off 40 watts of light while only using the equivalent of 12 watts of energy. Over the lifetime of the bulbs, your estimated saving is $148.00
Now that is what I call saving money. Simply replace the standard incandescent bulbs with the compact fluorescent light bulbs and that is all. Just see the link below if you are in search of new light bulbs.
