Instant Energy Savings - Instant Enjoyment Add warm & bright Bioluz LED energy saving LEDs to your home or office while maintaining the cosmetic beauty, brightness & halogen color you've come to love. We've found that bulbs which are over 5000K (Kelvin) generate a bluish tint on objects (like at a hospital or office building) and are not as comforting in a home. So while a higher number may sound better, it isn’t always. Many brands sell & market higher Kelvin bulbs with lower lumens to make them "appear" brighter. Bioluz LED manufactures the correct color bulbs with exceptionally bright, energy efficient LEDs, so you get the color & brightness you're accustomed to without the harsh effect of higher color temperatures. Energy Saving without the Sacrifice Bioluz LED Energy Saving Bulbs turn on instantly just like an incandescent bulb, while saving you a substantial amount of money on your electricity bill. For example, when used 3 hours a day & 365 days a year, our LED lamps will last an unprecedented 23 years! And the best part: they use $0.72 per year in energy!
