Howard Lighting is committed to quality!
We constantly test and evaluate our products.
Testing and Evaluation of lamps
• We are testing all lamps on our burn in racks,
plus in our photo sphere for lumens, color,
CRI, etc.
• Each production run is tested at the factory
and again when the product is received in our
warehouse.
• Independent testing has also be conducted
on several lamps.

ANSI Code
This code is developed
and assigned by the
American National
Standards Institute. The
ANSI Code consists type
of lamps as S=HPS,
H=Mercury, M=Metal
Halide and followed by
ballast number. For Metal
Halide lamps, the ballast
number is followed by the
fixture requirement (O, E,
S).
LCL = Light Center Length
Measurement from the center of the arc tube to
the bottom of the lamp base
MOL = Maximum Overall Length
Measured as the maximum distance from the
top of the bulb to the bottom of the base.

Start, and Mercury Vapor.
Information regarding HID Lamps
Average Life (Hours)
Average life is defined as the total operation hours at which 50% of any group of lamps is still under operation.
The average life of a lamp is based upon vertical operation of representative lamps operated under controlled
conditions of at least 10 hours per start (except MH1500 which is based on 5 hours per start).
Warm Up Time
Most HID lamps do not have instant capabilities. It may take several minutes for the arc tube to stabilize before
optimal light output is achieved.
Hot Restrike
In most instances, if an HID lamp experiences a momentary power interruption or sudden voltage drop, the lamp
may extinguish. A lamp that is still hot will not restart immediately, because the arc tube within the lamp must
cool down before it can re-start. HID lamps have hot restrike times ranging from 1-15 minutes depending on the
product type.
Information regarding HID Lamps (cont.)
Fixture Requirement
Developed by the American National Standard Institute (ANSI), the fixture requirement code describes the type of
fixture required for each lamp type. See lamp warnings for additional information and proper operating
instructions.
E = Lamps classified as E-type are to be used only in suitably rated enclosed luminaires.
O = Lamps classified as O-type, comply with ANSI Standard C78.387 for containment testing and may be used in
open luminaires.
Color (Correlated Color Temperature – CCT)
The correlated color temperature (color) of a light source is expressed in Kelvin (K). Kelvin is a means of
describing the appearance of the lighting space. “Warm” light sources have a low color temperature (2000-3000K)
and feature more light in the red/orange/yellow range. Light with a color temperature (>4000K) features more blue
and is referred to as “Cool”.
With new installations or group relamps all color performance evaluations should be made after at least 100 hours
of operation. Additional changes in chemistry within the arc tube over the life of the lamp may also cause the
color temperature to shift as the lamp gets closer to the end of its rated life. To minimize color variation within an
installation, it is recommended that HID lamps be group relamped and run on equal operating cycles.
CRI (Color Rendering Index)
CRI is an international scale (numbering system) up to 100 indicating the relative color rendering quality of a light
source when compared to a standard reference light source of the same chromaticity (color temperature). The CRI
expresses the degree to which colors will appear under the light source selected. In general, the higher the CRI
number, the better the color rendering properties of the light source being measured.
Information regarding HID Lamps (cont.)
Bulb
Each bulb description consists of both a letter to indicate bulb shape and number to show the maximum bulb
diameter in 1/8 inch increments. Example: BT37 bulb indicates a blown shape with tubular top, 37/8 of an inch in
diameter. Various bulb shapes are noted below.
Lamp Base Information
• Medium (E26) – bases are used on
E17 bulbs and limited to 175w
maximum.
• Mogul (E39) – bases are used on
High Pressure Sodium, Metal
Halide, Pulse Start, and Mercury
Vapor lamps.
• Mogul (EX39) – exclusionary Mogul
bases are used on Metal Halide and
Pulse Start lamps, permitting them
to be use in open fixture
applications. These bases are
compatible with standard or
exclusionary sockets.

Lumens Initial, are
measured when the
lamp has been
operating for 100
hours.
Lumens Mean, are typically
measured at 40% of
rated lamp life.
CRI (color rendering index), is an
international scale (numbering
system) from 0 – 100 indicating the
relative color rendering quality of a
light source when compared to a
standard reference light source of
the same color temperature. The CRI
expresses the degree to which colors
will appear “familiar” or “natural”
under the light source selected. In
general, the higher the CRI, the
better the color rendering properties
of the light source being measured.

lighting. SBCF lamps provide maximum lighting that last
up to ten times longer than their incandescent
counterparts and use only about one-fourth of the energy,
allowing for a savings of about $12-$77 in energy cost.
Products offered are mini spiral, decorative, globe, A
shaped and reflector.

• Wall sconces
• Retail
• Task Lighting
• Hotels
• Residential
• Surface ceiling fixtures
• Enclosed indoor/outdoor
