6000
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
Yes, you can run a 400-watt metal halide (MH) bulb in a 600-watt high-pressure sodium (HPS) fixture, but you need to ensure that the ballast is compatible with the MH bulb. Using a 400-watt MH bulb in a 600-watt ballast may lead to reduced efficiency, as the ballast will deliver more power than the bulb requires. It's essential to check the ballast type and ensure that it can operate both bulb types safely. If not compatible, it's best to use the appropriate ballast for the MH bulb to avoid damaging the bulb or the fixture.
Standard rule, top to the fixture same height as top to the door.
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.
Similiar to a flourescent light. The ignitor provides a high voltage potential to excite the sodium gas within the 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.
A 250 watt high pressure sodium bulb typically has a lumen output of around 28,000 to 30,000 lumens.
A 250-watt HPS (High Pressure Sodium) bulb typically produces around 28,000 lumens at the initial phase of operation. However, this can decrease over time as the bulb ages.
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
High pressure sodium light fixtures are beneficial for outdoor lighting because they provide bright and efficient illumination, have a long lifespan, and are cost-effective in terms of energy consumption. Additionally, they are known for their ability to enhance visibility and security in outdoor spaces.
Signs that a high-pressure sodium bulb may be going bad include a decrease in light output, flickering or inconsistent illumination, or a change in color temperature (turning more pink or purple). If the bulb fails to turn on or requires frequent replacement, it may be time for a new one.
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
High pressure sodium lamps produce a brighter, more efficient light compared to low pressure sodium lamps. High pressure sodium lamps also have a longer lifespan and better color rendering properties. However, low pressure sodium lamps are more energy efficient and have a monochromatic yellow-orange light output.
It makes your Blood Pressure high by the sodium in it, which is he salt and carbs.
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'
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.
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.
