- Energy efficient replacement for a 175/250 watt HID bulb
- Estimated life of 45.7 years based on 3 hours use per day
- No lead or mercury means easy and environmentally safe disposal
The Lunera Susan Lamp 250W/175W is a horizontal mount plug 'n play replacement for metal halide (MH) lamps with an E39 mogul base. With a significant lower energy consumption than conventional metal halide lamps, this LED lamp replaces a 175 watt or 250 watt metal halide lamp. Lunera's BallastLED technology makes the lamp truly plug 'n play by allowing it to operate directly off of a 175 watt (M57) or 250 watt (M58) existing metal halide ballasts. Simply replace the existing metal halide lamp with the Susan Lamp without making any modifications to the fixture.
- Replaces a 175 watt or 250 watt metal halide lamp
- Proprietary Thermal IQ™ Lunera technology enables the Susan Lamp to operate reliably up to 150ºF ambient
- Plug 'n play installation with existing installed magnetic ballast
- Ultra-low energy draw, extends existing magnetic ballast life
- Can be used in enclosed fixtures
- This lamp is NOT approved for use with line voltage
DO NOT "hot swap" this lamp. Turn off fixture before replacing existing bulb. This lamp only operates on existing magnetic metal halide ballasts. If the lamp does not light when the luminaire is turned on, remove the lamp from the luminaire.
A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
The wattage value of a High Intensity Discharge (HID) bulb of similar brightness.
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 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.
|-40 to 150
|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.
|5 year limited
The ANSI (American National Standards Institute) code that the ballast conforms to. For HID bulbs, indicates that the bulb is compatible with ballasts that conform to that standard.
Suitable for an exterior or interior location that is subject to condensation of moisture in, on or adjacent to electrical equipment
|Rated for Fully Enclosed Fixtures
Rated for Fully Enclosed Fixtures
Not all LED bulbs are suitable for use in enclosed fixtures, due to the amount of heat they generate. Rated bulbs have been tested and approved as safe for enclosed fixtures.
