RECOMMENDED LIGHTING BULB CHOICES Check the Size of LED bulb: Not all LED light bulbs are the same size as your existing halogen light bulbs. Some LED light bulbs are slightly larger than normal halogen bulbs, so check the dimensions of the bulb before you buy as it might not fit in your light fitting. In searching for halogen bulbs, I found descriptions like T8 or T1-1/4，But diameter are T8=25.4mm or T1-1/4=4mm. That is where the imperial T-bulb measurements come into play and where it gets confusing. Most halogen bulb uses imperial measurements that are in increments of T1=1/8". And most led bulb uses metric measurements that are in increments of T1=1mm. Base Configuration: When you buy LED bulbs, You must match the base sizes. Most common household fixtures have pin or Edison, also known as screw-in, bases. Types of lamp bases include: Check the operation voltage of your existing bulb, Low voltage 5V, 12V, 24V, 28V, 32V, 36V, 48V or Mains voltage operation 110V, 220V, 277V? We have one sub-catalouge LED light bulbs can work on all the mains voltage between AC 85V and 277V. 277 Volts is the input power of choice for most industrial and commercial applications. High voltage lighting is better from an efficiency standpoint. Higher voltage means less current, which means less power loss from resistance as stated in Ohm's and Joule's laws. Ohm's law: Voltage = Current*Resistance. AC 277V Commercial Lighting, AC 277V commercial led bulbs lighting Calculation power consumption and light output lumens Quartz halogen bulbs are now available in sizes from 60 watt to 150 watts. An advantage is their long life of 3,000 hours versus 750 hours for regular incandescent lamps. Compact fluorescent lamps are generally available in sizes up to 28 watts, which are rated at 1,750 lumens output. Compact fluorescents are generally rated to last up to 10,000 hours. Larger compacts fluorescents, up to 42 watts and 3,000 lumens output are available, but the 42 watt size requires a direct wire ballast to keep the bulb from sticking down below the skycap. The socket of the fixture would then have to be removed and the direct wire ballast wired and affixed into its place. In regular light bulbs, it is recommended that the hours of operation per night be kept to one hour or less. This way their limited life of only 750 hours will not necessitate replacement more often then every two years. If the light output of the 7,000 lumens output 175 watt mercury vapor light is desired, a 300 watt incandescent rated at 6,300 lumens output is available. Bear in mind at only 1 hour a night even a 300 watt light will still use 87% less electricity. Other options include yellow "bug lights" and even red lights if dark adaptation retention is desired while still being able to see for safety purposes. The replacement bulb calculation from incandescent bulb to CFL was quite easy. The chart was clear: 1W LED = 3W CFL = 15W Incandescent lamp = 8W Halogen lamp For the LED light bulbs, LEDs provide long life, pure white light, are available in colors, and are shock and vibration resistant. That means you can use bulbs with LEDs on equipment or household and potentially never having to replace them. Bulbs with LEDs as the light source will work from -40 degree Fahrenheit to +185 degree Fahrenheit. It is more energy efficient and more long lifetime (up to 100000 hours) than any other lighting, And it is better for a fixture with better control over the time switching options. It is best one for mounted in such a fixture could be switched on and off with a motion sensor, a remote switch, or a photocell timer. As a replacement for regular bulbs, The popular use is spotlight and table reading lamp. The cheapest is using multiple white LEDs, But due to the size limited of bulb, The MR16 most 48 LEDS, MR11 most 9 LEDs, GU10 most 48 LEDs, The largest PAR30 and PAR38 bulb just 120 LEDs (about 260 lumens, 10 watts output, Instead of 100 Watts incandescent bulb). For more big watts output, Should be use high power LED, But the price will be higher than multiple white LEDs. Currently, We can make largest watts output is 60 watts. It can instead of 500 watts incandescent bulb. For decoration lighting and lighting for entertainment, The LED light bulb is best lighting. The beam angle is very important when you choose LED light bulbs, The angle can be 15 degree, 30 degree, 45 degree, 60 degree. The lumens will be less for wide beam angle LED light bulbs. When you calculate the lumens of led lights replacement, You must consider the bulb is directional light bulb or non-directional light bulb (this is very important). For example, The compact fluorescent light tube is 360 degree beam light output, And the LED ligth tube is 120 degree beam light output. The lumens of 36 watt CFL is about 3200 lumens, If you use led light tube as repalcement, computational formula is (3200/360)*120 (this is consider the beam angle of directional light)+(3200/2)*50% (this is consider the lumens of reflect light) =1866 lumens of led light tube is enough. White LED Color Temperature Options (in Kelvin) : Warm white 2200K~3500K, Pure white 5500K, Cool white 8000K. Viewing angle options: Narrow angle 10~20 degree, Medium angle 40~60 degree, Wide angle 90~100 degree. High power LED bulbs compare with multiple white LED bulbs, The cost of high power LED will higher than multiple white LED, The efficiency of multiple white LED bulb will better than high power LED bulb. If you just like the light output and price, Please choose our multiple white led bulbs. But please note that the Life and Lumen Maintenance of high power led bulbs are better than multiple white led bulbs. Installation Led Retrofit : Replacing high pressure HPS sodium and CFL retrofitting using 2D LEDs. You can take off the ballast that is in the fixture. This will reduce your costs because you won't have to purchase costly lifts. It's simple to retrofit.There are a variety of LEDs. There are two types of LEDs, reflectors and lenses. They can be utilized to concentrate or scatter light. The power of LEDs is its capacity to precisely identify the color they produce. The second column of the chart is referred to as LED Wavelength. It's the amount of light that is released. The strip lights are the most frequently used kind of lighting that you can paint with. Each end comes with two contacts.Find the efficiency of energy-efficient bulbs that are made of LED before you purchase. LED Light Unlimited has a broad assortment of light bulbs that are made of LED that will assist in choosing the right one for your needs. |
