Unlike incandescent bulbs Cheap Brian McCann Jersey , high-power LED tube lighting cannot be simply plugged into a wall socket. Several companies are working to overcome the technological and economic challenges by developing LED light fixtures and retrofit LED light tubes using high-power LEDs. Thermal management, complex drive circuitry, optics, and packaging are challenging hurdles for developers to contend with. There are also educational barriers to overcome in the development of commercial LED illumination products. Getting users to adopt new types of fixtures, understand the illumination characteristics of LEDs, choose the appropriate viewing angle for a given application Cheap Dansby Swanson Jersey , select the appropriate intensity for a given application, and understand the limitations of LED color temperatures are pivotal to developing the market for LED technology in commercial and residential lighting.

The Illumination Angle

LEDs are extremely energy-efficient from an illumination efficacy standpoint, i.e., lumens per watt. Upwards of 95 percent of the light can be directed at the target area of illumination whereas a typical incandescent bulb may be only 60 percent effective. In other words, a lot of the light produced by an incandescent bulb does not go to the intended target. Incandescent bulbs require reflectors, louvers Cheap Freddie Freeman Jersey , andor diffusers to compensate for unnecessary light. Fluorescent bulbs are more energy-efficient than incandescents, but the ballast may consume up to 20 percent of the electrical energy going into the fixture. Retrofitting LED technology in traditional luminaries is tricky because most fixtures are designed to overcome the limitations of traditional spherical light output. Reflectors, cones, masks, shades and diffusers help bend, redirect Cheap Hank Aaron Jersey , or shield the light emitted from incandescent, fluorescent and halogen sources, but it creates unnecessary physical barriers for implementing LED technology. Designing specific forward-fit LED-based luminaries can produce several times foot-candles on a given area per watt than other traditional incandescent bulb technologies. Because of the directional illumination pattern that LEDs provide the light can be directed to the specific area that needs to be illuminated.

The Light Color

Over the years, fluorescent bulb manufacturers had some challenges getting users to accept the white color produced by fluorescent technology. Because of the limitations of phosphor technology, the fluorescent industry introduced subjective terms such as "cool white" or "warm white" to draw comparisons to incandescent white. Not coincidentally, white LED manufacturers face the same challenges since white LED technology is based on phosphor energy. To put things in quantitative perspective Cheap Greg Maddux Jersey , LED manufactures have referred to Color Rendering Index (CRI) which is a measurement of a light source's ability to render colors accurately. The higher the CRI, the more natural the colors appear, with natural sunlight having a CRI of 100. However, this may not be the best metric for comparing light sources.

But the bigger issue is, the light intensity benchmark for an LED fjuorescent tube lamp is not the watt. Traditional LEDs used for simple status indication and displays come in small epoxy packages and their light output is measured in candelas because this is a measurement of direct-view luminous intensity. With the recent development of high-power LEDs for illumination purposes, the lux or lumen (one lux is equal to one lumen per square meter) is a more suitable unit of measurement to compare the LED tube light lamp output to traditional sources because we are more concerned about the volume of light rather than the directional intensity.


?Then Gideon said to God Cheap John Smoltz Jersey , `Do not be angry with me. Let me make just one more request. Allow me one more test with the fleece'" (Judges 6:39).


Some ask how much proof Gideon needed that God had his best interests in His tender heart? God had already assured Gideon of his success, but Gideon wanted to check, recheck and double check. But perhaps we are unfair to Gideon; perhaps he feared he misunderstood God's intentions and he needed to be more certain of his own interpretation. Don't we all have such moments? Gideon never questioned God's power or purposes to save Israel. In his humility he doubted his own ability, just as did Moses when God tapped him for the job of leading the Israelites out of Egypt. God did not reprove Gideon for his request; indeed, He immediately granted it, knowing that the weakness is more of nature than of faith Wholesale Braves Hats , and physical rather than moral. It was in this very nature of doubt that Gideon asked God not to be angry with him. Gideon knew that he asked a double portion of proof, as we all do daily.


All great saints feel doubts. It's a part of nature to feel. Faith is the knowing that God is good and just and holy; the feeling of doubt creeps in when the circumstances just don't fit. Thoreau said, "Faith keeps many doubts in her pay. If I could not doubt, I should not believe." Doubt isn't always dispute. Indeed, the more we know about God, the more doubts we may have about ourselves Wholesale Braves Hoodies , especially. This is meekness, a virtue God treasures.


We prove God every day by asking for new strength for new duties. We don't ask for miracles, for they abound anyway; we ask, as did Gideon, that our fleece be saturated with His dew: gratitude in our hearts and holiness in our life.


The internet has opened up incredible opportunities for the average consumer, as these opportunities were only available to wholesalers and retailers prior to now.


Remember as you search Wholesale Braves Shirts , that the companies you are researching are competing to get your business. This makes buying parts for your air compressor more affordable than it has ever been.


Because air compressors are so frequently used in manufacturing plants and other industries and because they have the potential to be dangerous to work with,.
