Halogen 60 W 900-1000 For energy efficiency and safety, ensure the bulb's wattage does not exceed your fixture's maximum rating. LED bulbs, providing more lumens per watt, are a superior choice for both brightness and energy conservation. How Much Does It Cost to Run a Light Bulb?
Not sure how many lumens you need? You can estimate what you need based on what you had installed before switching to LEDs. This can be calculated using an approximate conversion factor of 10 lumens per watt: Lumens = [watts in incandescent] x 10 For example, if you had a 65W incandesce...
For example: You could have a LED down-light, a Compact Fluorescent Lamp and an Incandescent bulb that all have different wattage per bulb but by using Lumens you can work out the light output produced. 40-watt incandescent bulb = 450 lumens 29-watt Halogen = 450 lumens 9-watt LED = 45...
One way to compare lamps is by looking at how much energy they need (measured in watts) to produce the same amount of brightness (measured in lumens). Dividing these two numbers, we get the number of lumens each lamp can produce for a single watt of energy. Looking at the chart here,...
It had half the clarity of a second hand infocus $80 halogen projector of 800 ACTUAL lumens. All I can find on youtube is sales videos of people trying to make money out of saying how great the videos are... Are the chinese actually producing anything half reasonable yet? Has much chan...
It’s a rite of passage to have a dark (maybe even windowless) room at some point in your life – You aren’t alone and I can solemnly say that a small room with little natural light is one American’s biggest design agonies. If natural light is our design best friend, then the la...
What are the smallest lumens to closely equal a 15-watt light bulb? I am night blind and use small lamps in my bedroom and hallway (standard base) at night. I can’t seem to find this wattage anymore, or it has so many other stats piled on it I can’t figure out the actual watt...
