Back then I loaded up on incandescent bulbs. I thought I had a 20-year supply. I’m now down to my last several. :-(
You can use whatever you want. Buutt. I’ve been using LEDs and CFLs for years. They use less electricity, run cooler and last longer than incandescent. I have one pair of LEDs used for outside porch lights that have run 24/7 since 2013. They burn 24 watts but have the output of 100s. Big money savers. The cheap WM LEDs don’t last long enough to justify the cost imo so I shop around. I have a few CFLs that have been running since 2007.
CFLs sucked because of the color, but LEDs are awesome. Less energy, last longer…make the switch!
