They're not as bright as 40w incandescent bulbs but generate almost no heat which leads me to believe they use very little power. Since there are 12 bulbs in my chandelier, there is enough light. All LEDs aren't as pretty as the old flame-shaped incandescent bulbs, but they aren't as ugly as most either. However, I wish the tubes weren't so bright yellow. The price is unbeatable! So far happy with this purchase.
