What is CFL mhl and hpmv lamps?
The abbreviations are CFL - Compact Fluorescent Lamp, MHL - Metal Halide Lamp, HPMV - High Pressure Mercury Vapor, and one more is HPS - High Pressure Sodium lamp
How high from the floor do you install an entry light?
Standard rule, top to the fixture same height as top to the door.
How many watts will a 150 watt High Pressure sodium light with a capacitor draw?
It will draw 150 watts. The capacitor is there only to increase the voltage enough to "excite" the free electrons in the gas to ignite.
How does ignitor in sodium vapour lamp work?
Similiar to a flourescent light. The ignitor provides a high voltage potential to excite the sodium gas within the bulb.
Why use 277v light fixtures instead of 110v light fixtures?
277v light fixtures are more efficient to operate and less expensive to install than a 110v fixture of identical wattage. 277v light fixtures are typically installed when 480V 3 Phase primary electric service supplies a commercial or industrial facility. 277v lighting circuits are single phase circuits using one of the 480v primary phases (A,B & C) to Neutral. The higher voltage allows more fixtures per circuit using smaller conductors and longer runs typically required in warehouse lighting applications. ( Amps = Watts/Volts: 400W/277V Fixture = 1.4 Amps, 400W/110V fixture = 3.6 Amps) With 480V 3 Phase primary service, 110V Single Phase power is created using a Step-down transformer. The voltage transformation process consumes power (kWh) and the 277V fixture will consume less kWh than a 110V fixture if identical wattage, especially in fixtures with ballasts such as fluorescent or High Intensity Discharge (HID), like Sodium, Metal Halide or Mercury Vapor.
How many lumens are in a 400 watt mercury vapor light bulb?
A 400 watt Mercury vapor light bulb produces roughly 23,000 lumens. In comparison to a 400 watt metal haloid and or high-pressure sodium, not as good. Metal haliod and high-pressure sodium produces 30,000 lumens.
How do you tell if high pressure sodium bulb is bad?
my HP sodium light just quit working. How can I tell if the bulb is out or the fixture mounted on the pole is bad. Hate to pay $35 for a bulb if the fixture is the culprit.
Lumen output of a 250 watt high pressure sodium bulb?
28,500 Lumens (approximately) there will be variance for other factors including manufacture.
Why cfl is widely used nowadays?
Compact fluorescent bulbs are widely used because they use one fifth of the electric power to provide the same amount of light as an incandescent bulb. Incandescent: 12 lumens per watt Halogen: 15 lumens per watt CFL: 50-60 lumens per watt LED: 100 lumens per watt High-pressure sodium: 200 lumens per watt
How bright is 950 lumens?
220 lumens is equal to a tungsten incandescent light bulb of 15 watts. Halogen lamp 20 watts. Fluorescent lamp 60 watts. LED lamp 60 watts. high pressure sodium vapour lamp 117 watts. Mercury vapour lamp 50 watts or 17.32 candle power
Can you use a 277 volt high pressure sodium light in my garage?
Not unless you have 277 volts in your garage. Open the fixture and check the ballast. Some of the commercial fixtures have multi tap connections for different voltages. If 120 or 240 volt tap is present then you can use the fixture.
What is the difference between high pressure low pressure sodium lamps?
the pressure ;)
What is a possible result if you have too much sodium?
High blood pressure can result from a diet too high in sodium.
How does pizza make your blood pressure high?
It makes your Blood Pressure high by the sodium in it, which is he salt and carbs.
Is argon gas a part of a high pressure sodium lamp?
From Wikipedia, high pressure sodium lamps use xenon, whilst low pressure ones use neon with a small amount of argon. See entry for 'sodium vapor lamps'
What do health claims specialist do?
Diets high in sodium may reduce the risk of high blood pressure. Diets low in potassium and high in sodium may reduce the risk of high blood pressure and stroke.
Where can one buy high pressure sodium bulbs?
High pressure sodium light bulbs can be purchased at many retail locations. Some of these include Canadian Tire, Lowe's, Home Depot, and Rona. Acklands Grainger carries industrial high pressure sodium light bulbs as well.
