GlobaLux non-dimmable 12 watt 48" 3500K glass T8 LED hybrid bulb features a dual mode internal driver that automatically adapts to either ballasted fixtures or direct AC voltage formats. The internal driver is compatible with most instant start ballasts, or remove the ballast and power directly with 120-277 AC line voltage. Suitable for use in fixtures where ambient temperature is between -4 to 104°F. Can be used in lensed recessed troffers.
When connected directly to line voltage (120-277 VAC) this lamp must be wired for double-ended power. This means the line wire (typically the black wire) and the neutral wire (typically the white wire) must be connected to each end of the lamp. Non-shunted sockets must be used for a ballast bypass (line voltage) application.
- Works with or without a ballast. Compatible with most electronic and many magnetic ballasts. Power to the fixture must be turned off before replacing the lamp. Call one of our Lighting Specialists for details at 888.455.2800.
- Non-Dimmable. Do not use with dimming ballasts
- Direct replacement for F28 T8 fluorescent lamps
- Instant on, no flicker or buzz
- Fits into existing linear fixtures
- Emits virtually no UV rays or IR
- Can be used with shunted or non-shunted lamp holders
- Suitable for damp locations
A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
The total wattage of fluorescent lamps in a fixture that this fixture replaces.
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.
The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. For example, a common household bulb is the A-19. The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".
The color of the light produced by a bulb
Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.
|Color Temperature (Kelvin)
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).
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.
The surface finish of a bulb, which may affect the quality of the light emitted.
The technology implemented by the bulb, e.g. incandescent, halogen, LED
|Average Rated Life (hr)
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.
|Operating Temperature (°F)
Operating Temperature (°F)
The ambient temperature in which the product can safely operate.
|-4 to 104
|Beam Angle (°)
Beam Angle (°)
The width of a light beam, expressed in degrees. The beam angle is often part of the ordering code for reflector lamps. For example, a 50PAR30/HIR/NFL25 is a 50-watt PAR30 narrow flood lamp with a beam angle of 25 degrees.
|Bulb Power Type
Bulb Power Type
Defines how a lamp is powered, whether it needs a ballast or not, or can use either
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.
Light bulbs: a measurement of a bulb's width taken at the widest point of the bulb. Fixtures: the measurement across the widest point of a circular fixture.
Type of socket a linear lamp is compatible with, whether shunted, non-shunted or both.
