Watts Per Lumen Comparison

Light Bulbs at a Glance Lumens are a measurement of the perceived power of light. All ratings approximate.

Incandescent

This is the traditional "Edison" light bulb. It emits light in a warm, broad spectrum; however, approximately 90% of all the power consumed by an incandescent light bulb is emitted as heat rather than visible light. Given far more efcient alternatives, some governments are mandating a phase-out or ban of its use.

Halogen

Halogen is a form of incandescent. It has the truest color rendering of any light source other than the sun and is therefore often used to illuminate works of art. In the MR16 format, this long-lasting, low-voltage spot is amplifed by an integrated refector, greatly increasing its apparent efcacy.

35 600 17 46 .077
50 900 18 65 .072

Fluorescent Tube T5 T8

The improved ficker-free fuorescent tube ofers good color rendering, long life and low cost. Like all fuorescents, special disposal measures are required due to mercury content.

Compact Fluorescent (CFL)

CFLs use less energy than incandescents and can last up to eight times longer (if not overheated) while generating light that is becoming increasingly comparable. CFLs contain trace amounts of mercury, requiring special disposal measures. The ballast must be discarded along with this type of lamp.

18 1100 61 23 0.020
23 1600 69 30 0.018

CFL non-integrated ballast

These CFLs utilize separate, reusable electronic ballasts; they are slightly more efcient and can last longer compared to integrated-ballast CFLs. One ballast will often run multiple wattages and permit dimming. Lamp disposal issues are the same.

Ceramic Metal Halide

Metal Halide is an efcient, high-output lamp commonly used to illuminate large outdoor areas, in part because its output is unafected by environmental temperature changes. Due to high intensity and slow start-up, it is best suited for outdoor and commercial applications. MHs contain mercury, requiring special disposal measures.

High Pressure Sodium (HPS)

These lamps are typically used for streetlights and security lighting, where color rendering is not critical. HPS lamps contain trace amounts of mercury, making disposability an issue, and they decline in lumen output as they age. White¡°SON¡± is a higher cost HPS variant with a high CRI but reduced life and efcacy.

Light Emitting Diodes (LEDs)

LEDs are a promising technology currently undergoing rapid development. Their warmth and color rendering can be comparable to incandescent in certain applications. Their small size makes them highly versatile. Given their long life, high efciency and low toxicity, their cost is likely to be justifed over time.

Please Note:

If sodium lamps break, ventilate the area where breakage occurred. Clean-up with vacuum cleaner or other suitable means that avoids dust generation. Take usual precautions for collection of broken glass. Clean-up requires special care due to the fact that sodium reacts with the moisture on the skin and in the air. Materials from broken lamps should be treated as for spent lamps.

To avoid the risk of sodium reaction when disposing of spent lamps, the following procedure should be followed:

Comparing Efficiency Is Easy

The lumens and wattage will often be given on the packaging or on the bulb itself. To compare bulbs for efficiency, determine the number of lumens the bulb will produce per watt by dividing the lumens by watts. The lower the result, the more efficient the bulb. For example, an 9-Watt, 900-lumen LED bulb produces about 100 lumens per watt (that is 900 divided by 9). A common 60-Watt, 830-lumen incandescent bulb produces only 13.5 lumens per watt.

Energy saving lighting

Lighting accounts for around 10 to 20% of the electricity bill in a typical home. Although the good news is that where an effort has been made to replace old-fashioned lighting with more energy efficient products, the proportion, and the overall electricity bill, will be lower.
