But the dollars and cents don't stop there. You need to factor in the cost of using the bulb -- and the great thing about LEDs is that using them doesn't cost very much at all. For instance, a traditional 60-watt incandescent lightbulb will add about $7 to your energy bill eac...
I'm sure you've heard about watts, but fortunately almost every bulb has become more energy efficient so while a box will list the watt equivalent conversion, what you should really be looking at is Lumens! What are Lumens? Watts measure the amount of energy required to light products, whe...
The lumen (lm) is the real measurement of brightness provided by a light bulb, and is the number you should look for when shopping for LEDs. For reference, here’s a chart that shows the watt-lumen conversion for incandescents and LEDs. As you can see in the chart above, an incandesce...
Can You Change a Light Bulb on Your Sewing Machine Light? It depends on the type of sewing machine light you have. Some models work with replaceable bulbs and some do not. Please check the manual to see if your product allows it. If yes, and it is your first time changing a light ...
The LT1301 regulates L1's current to equalize Q3's average collector current, representing 1/2 the lamp current, and R1's cur- rent, represented by VA/R1. C1 smooths all current flow to DC. When VA is set to zero, the ILIM pin's bias current forces about 100μA bulb current. ...

Efficiency of LED devices continues to improve, with some chips able to emit more than 100 lumens per watt. SUMMARY What is needed is a device that has the same or better efficiency of a LED light bulb but less expensive to produce. Another aspect can be one that gives the consumer more...
