Do you use AC?
A lot of the energy from halogens goes directly into heat
I had (2) 20w halogens over the stove & repleced them with (3) LED
Halogens - 40w, 3 LED's = 4w
What type of bulbs are installed....MR16?
They do make MR16 LEDs, many different wattages & styles
I'll be using a 150w halogen torchiere lamp in colder weather when I'm working on electric & insdulation in the new addition - just to add some heat
68 *50w = 3400 watts
68 * 1w LED = 68 watts total
Cost of electric is not going down in most areas of the country
