How to choosing the right energy saving corn LED lamp to replace mercury lamp?

Brightness—Making sure it’s bright enough

Obviously, the first factory that comes to mind when we think of a bulb’s performance is brightness. Shop for lumens, not watts, same watts higher lumen output is better. Watt are a measure of how much energy the bulb draws, not its brightness.

For example:

A 125W HWL mercury lamp will output 1625 lumens, A 120W LED corn light will output 16530 lumens, taking a look at efficacy, which is simply found by dividing the lumen output by the wattage necessary to power the bulb, the mercury lamp outputs 13lm/W while the LED corn bulb achieved 130lm/W.

LED corn light also are rated by watts. But that’s no help because there’s no easy way to compare LED watts with HID, MH, HPS, and CFL lamp’s watts. Here isn’t a uniform way to convert traditional lamps’ watts to LED watts.

Now, instead of watts, use lumens as the yardstick of brightness. Packing on LED bulbs rates brightness in lumens ( and in watts). To replace a 250W mercury lamp, look for an LED corn light rated at 5389lm (40Watt TEK LED corn bulb ), Here is a handy comparison chart:

HWL lamp	Rated Wattage	Luminous Flux	CRI/Ra	Efficacy	Luminous Flux	CRI/Ra
125W 240V E27	125W	125W	240V	13.2lm/W	1650lm	66

E40 LED Corn lamp	80W	84W	100-300V	130lm/W	11000lm	80
Low CRI, High lumen output.

Color Rendering Index— Accurate color replication

The Color Rendering Index, or CRI, of a source indicates how well it renders eight standard colors compare to a perfect reference lamp of the same color temperature. The comparison is only valid for lamps of same color temperature.

A LED lamp with a CRI of 80 will render colors better than a lamp with a CRI of 60

Any decent LED manufacturer will publish the product's Color Rendering Index (CRI). This is an adequate (though incomplete) measure of the light's color fidelity. CRI is measured on a scale from 1-100, the higher the number, the more likely the light source will render object color well.

For a primary industrial lighting source, you shouldn't go below a CRI of 70.

Color Temperature — Specify the light color you want

Different light bulbs emit different colors of light. Lighting color ranges from cool to warm tones, and is known as color temperature. The color temperature of a light source indicates the color of the light emitted measured in degrees Kelvin. Color Temperature is not an indicator of lamp heat. The chart below shows a range of color temperatures, from warm to cool.

Color temperature is also important, and it is easily misunderstood. "Warm" light actually has a lower temperature — incandescent bulbs are 2,700K, HWL mercury lamp color temperature from 3300K to 4100K.All LED corn light lamp have a full range from 2700K to 6500K. Usually industrial lighting consider to using nature white:4000-4500K and Cool white:6000-6500K

Let's study from a different color temperature creat a difference atmosphere in a same room.

LED corn bulb cut your spending on electricity by 80 percent to 90 percent.
