How many lumens is 70W SON?
Philips SON 70W 220 I E27 light bulbs you provide a superior quality light with a luminous flux of 5600 lumens.
What gas is in a SON lamp?
These lamps contain noble gases like: argon, neon, krypton and xenon. They come in three different forms: high pressure discharge, low pressure discharge and high-intensity discharge.
WHAT LED is equivalent to 500W halogen?
Halogen bulbs’ lumens per watt falls within the range of 14 to 20 lm/W. And hence, a 500W halogen bulb produces 500 * 14 = 7000 lumens. If we convert this watt to LED, we will get 7000 ÷ 140 = 50W.

What Colour of light sodium lamp produces?
When the lamp is first started, it emits a dim red/pink light to warm the sodium metal; within a few minutes as the sodium metal vaporizes, the emission becomes the common bright yellow.
How many lumens does a 500 watt halogen light put out?
ILLUMINATE YOUR HOME WITH HALOGEN LIGHT BULBS: These 500-Watt T3 bulbs output 11,100 Lumens. WHITE LIGHT BULBS: The clear light bulbs illuminate your home with white light.
What is the average life of sodium vapour lamp?
The efficiency of a sodium vapour lamp under practical conditions is about 40-50 lumens/watt. Such lamps are manufactured in 45, 60, 85 and 140 W ratings. The average life is about 3000 hours and is not affected by voltage variations.Sha. 23, 1438 AH
Which ballast is used in sodium lamp?
Operation. The inductive ballast is made up of a coiled wire. The coil creates a magnetic field inside when a current is applied. It stores the energy of the current in the magnetic field it creates.Raj. 27, 1438 AH
Which lamp is cheapest for same wattage?
|Which of the following lamps is the cheapest for the same wattage?
|mercury vapour lamp
|sodium vapour lamp
What is 500W halogen equivalent to in LED?
50W / 50
50W / 50 Watt Super Bright LED Floodlight = 500W Halogen.
What is the light output of a 70 W halide?
As seen in the Relux output, the average light output is 545 lux when using a 70 W metal halide at a spacing of 2,5 m. Comparing 70 W metal halide with LED down lights
Which is an example of the light output ratio?
The Light Output Ratio is the ratio of the total amount of measured lumen output of a light fitting (containing a lamp) to that of just the lamp in isolation. By way of an example – take an industrial or warehouse high bay light fitting with a LOR of 70%: this indicates that 30% of the lamp’s light output is lost due to the design of the fitting
Which is better 70 W metal halide or 15 W led?
As seen in Table 4 and Fig. 7, the 15-LED with a 30˚ spread spaced at 1,5 m is the closest comparison to the 70 W metal halide, spaced at 2,5 m. The graph shows that the 15-LED with a 30° lens can achieve the same intensity of light but the metal halide has a much wider spread of light.
What does lumen depreciation mean in LED lighting?
Lumen depreciation refers to the process of gradual decline in light output that is observed from most light sources over time. This includes (but is not limited to): LED lighting modules do not die instantly like most conventional light sources do – they slowly dim until the lumens output is no longer acceptable.
