Array Lighting

Energy Used

A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
Energy Used
1 Watt


A measure of "electrical pressure" between two points. The voltage specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.


The end (or ends) of the lamp that fits into the socket.

Bulb Color

The color of the light produced by a bulb
Bulb Color
Warm White

Color Temperature (Kelvin)

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).
Color Temperature (Kelvin)

Brightness (Lumens)

A rating of the initial light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.
Brightness (Lumens)

Bulb Technology

The technology implemented by the bulb, e.g. incandescent, halogen, LED

Average Rated Life (hr)

A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.
Average Rated Life (hr)

Length (in)

Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
Length (in)

Width (in)

For fixtures and ballasts, width is the measurement of the total horizontal distance from left to right of the product in inches.

Indicates whether a bulb can be dimmed in conjunction with a suitable dimmer control.

Product Notes: Excessive or Continuous Heat Build-up will Drastically Reduce the Life of LED Products. Well Ventilated AND Open Fixtures Are Required for Proper Light Output and Product Life. DO NOT HOT-SWAP THIS BULB-Turn Off Power To Fixture Before Installation. If Your Fixture Already Has a Lens, Remove It (If Possible) for Best Optics and Heat Exchange. NOT DESIGNED FOR OUTDOOR USE NOR FOR USE IN WET LOCATIONS.

Good power savers


A friend bought these bulbs for his motorhome and recommended them to me, my main reasons for using the bulbs are for energy saving and longer life. With the large amount of halogen bulbs in motorhomes both of those factors really add up. The energy saving is real and makes a big difference, as for the longer life I need much more time. Although these are the warmest bulbs we could find the are still very white and therefore a little harsh when directly compared to halogens. It takes a little time but you will get used to it, as well as the increased light you will get in your room. These bulbs dim pretty much all the way down which is excellent for creating a more subdued late lighting environment.

Replaces a 10W T4 Capsule bulb


[...] excellent build quality. I replaced eight 10W capsule bulbs in my RV. The replaced areas are three over the entertainment center and five over the couch and kitchen prep area. Even though the LED's have one watt of power, they appear brighter than the high energy bulbs. The light of the 3000 is warm. I did not order the 5000 as the light would appear harsh and the 6500 would appear almost blue. The use of LED's in our RV greatly reduce the power used during dry camping and save big dollars in excess running of the generator. Wish carried more LED's for RV applications. Another factor with LED's is that they are so much cooler than T4 halogen bulbs. Hope this helps others as I am amazed at the light output. Will know more, in the future, how durable they are; until then, I am a happy camper.
