1 Scope
This standard describes a system for the designation of high-intensity discharge lamps, including compact, enclosed-arc discharge light sources such as mercury, metal halide, high-pressure sodium, and similar types of lamps. For convenience, low-pressure sodium lamps, although technically not high-intensity discharge lamps, are included with the group.
There have been two changes since the 2005 standard. The first is a proposed addendum for the National Electric Code (NEC) as a normative annex for the assignment of physical codes for lamp and luminaire attributes.
The second is a proposed amendment to C78.380i -- a revision of paragraph 7 and addition of a new paragraph 8.
2 Purpose
The purpose of the designation system covered by this standard is to provide an identification code for use in ANSI standards. Some lamp marking requirements are also identified. Guidance is given as to which characteristics are important (key) to assure interchangeability.
The lamp characteristic data given by a manufacturer on a High-Intensity Discharge Lamp Code Designation (LCD) Request Form becomes the basis for the assignment of a designation. They have not been approved by the American National Standards Institute (ANSI) and do not constitute an American National Standard. Similarly, any consolidated listing of assigned designations with associated characteristics does not constitute an American National Standard.

characteristic number
5.3 Electrical
A number shall follow directly after the lamp type classification and it represents the set of all key electrical characteristics of the lamp in question, so as to ensure electrical interchangeability. One set of numbers is the source for all assignments of Characteristic numbers and Characteristic numbers can be used for more than one lamp classification type as long as the additional type conforms to the key electrical characteristics for an additional type in Annex B. For example, a 150W ceramic metal halide lamp that is intended to operate on a ballast intended for M102 quartz metal halide lamps would have the designation C102.
Key electrical characteristics are:
? Lamp wattage, rated
? Lamp voltage, rated
? Lamp operating current
? Lamp starting current
? Minimum open circuit voltage, rms
? Minimum open circuit voltage, peak
? Pulse height, where applicable
? Minimum pulse width, where applicable
? Pulse Repetition Rate (per half cycle), where applicable
? Pulse position, where applicable
? Maximum operating and starting current crest factor
? Minimum sustaining voltage, where applicable
? Maximum current off-time, where applicable
? Requirement for Protection from Rectification, where applicable

5.4 Luminaire
characteristic
An appropriate luminaire characteristic letter shall be assigned from the list given in Annex A.
5.5 Physical characteristics
Previous versions of this standard defined physical characteristic letters that were intended to be used as a simple marking to match lamps and luminaire. They represented a set of key physical characteristics of the lamp in question, so as to ensure physical interchangeability. These code letters are no longer used except for mercury vapor lamps. See the mercury lamp standard, C78.40 for the codes still in use. The key physical characteristics are as follows and must be specified on the lamp code request form:
? Base designation
ANSI_ANSLG C78.380-2007
Proposed Revision of ANSI C78.380-2005
? Bulb shape and diameter (major diameter)
? MOL, for single-ended lamps
? Distances B and C, for double-ended lamps
? LCL, for single-ended, non-reflector lamps with clear outer jackets
5.6 Temperature characteristics
These temperatures define the maximum limit to which the lamp may operate without deterioration to the lamp material. Any increase in the operating temperatures above these values may cause short life and/or lamp failures. The following temperature information must be provided on the lamp code request form:
? Bulb Maximum Temperature
? Base Maximum Temperature
5.7 Other information.
Restrictions on lamp operating position may be noted on the lamp code request form if appropriate.
5.8 Metal halide lamps, illustration of typical designations
Example Designation: M102/O
(As an example) “M” = Quartz Metal halide lamp classification. (Section 5.2)
(As an example) “102” = Electrical characteristic number (see clause 5.3)

7.1 Administrator
The lamp code designation procedure described in this standard shall be administered by the Secretary of Accredited Standards Committee C78 through the offices of the American National Standard Lighting Group (in affiliation with NEMA), 1300 North 17th Street, Suite 1847, Rosslyn, VA 22209.
7.2 Participants in high-intensity discharge lamp designation program (LCD)
Any domestic, foreign lamp manufacturer, or distributor who wishes to obtain designation assignments may participate by filing an initial Request Form with the Administrator. A roster is maintained for the Work Group 4 and HID Lamp Code Designation participants who have paid for this service.
The LCD participants consist of the members of the Work Group 4 and the HID Lamp Code Designation participants who have paid for the LCD information.
group
7.3 Advisory
Work Group 4 of Accredited Standards Committee C78 shall maintain this standard. In addition, it shall serve as an advisory body to which the Administrator or participants may bring questions.
7.4 Procedure for assigning and recording lamp designations
When an electric lamp manufacturer decides to make application for a designation for a high-intensity discharge lamp, they shall file with the Program Administrator a fully completed High-Intensity Discharge Lamp Designation Request Form (see section 7.7). The completed Request Form shall list all key characteristics that are necessary to describe a lamp sufficiently to allow assignment of a designation in accordance with this standard. The box at the top of the Request Form relating to a new designation should be checked.
The Administrator may reject any Request Form that provides insufficient information.
Assignment of a designation shall not be given over the telephone. Requests to reserve designations for further use shall not be accepted.
The Administrator shall review current records to determine if the information on the Request Form defines a unique set of key electrical characteristics, per the criteria of Section 6.2.
Upon acceptance of a completed Request Form and payment of fees, the Administrator shall take one of the actions outlined below.
1) If a designation has not been assigned to a lamp having the
electrical characteristics on the Request Form, the
Administrator shall, within 10 business days of receipt,
circulate the request to the Work Group 4 and the HID Lamp Code
Designation participants for review and comment for a period of
30 days. If objections are received that indicate a conflict
with industry safety practices, the Administrator
shall consult the requestor and attempt to resolve the
objections before issuing a new code. Otherwise, the
Administrator shall follow the resolution procedure in clause
7.6. If no objections are received, the Administrator shall
assign and list a designation for such a lamp in accordance
with the requirements of this standard and consult the
requestor. The requestor and the Administrator will have final
discretion on incorporation of comments received from the
Advisory Group.
2) If a designation has already been assigned to a lamp having the same
characteristics based on the criteria of Section 6.2 as given on the Request
Form, the Administrator shall inform the filing manufacturer of the existing
designation that may be used for his product.
After a new designation has been assigned and listed, the Administrator shall circulate copies of the completed Request Form to the Work Group 4 and the HID Lamp Code Designation participants.
Non-participants in the program may obtain copies from the administrator for a nominal charge per copy.
7.5 Procedure for a change in the characteristics of an existing lamp designation.
If a requested change will not affect electrical, physical, or safety interchangeability, the requested change should result in no comments being submitted. Conversely, if interchangeability were affected in any way, the change could result in comments
from one or more participating manufacturers.
If no objections are received in that period the changes are accepted and copies of the approved revised LCD form will be circulated to Work Group 4 and HID Lamp Code Designation participants program.
If objections are received, the change is put on hold pending the outcome of the resolution procedure given in 7.6.
procedure
7.6 Resolution
The Administrator shall consult with both parties. Should the Administrator be unable to resolve to both parties satisfaction, the item of dispute shall be referred to C78 WG4 to attempt resolution at their next regularly convened meeting. The code request or the proposed change to a code (that is not an ANSI standard) will be allowed only if a resolution is found that is acceptable to all parties.

8.0The Practice of Lamp Code Designations becoming American National Standards
LCD numbers are assigned by means of this written procedure. A LCD is not an ANS, or an ANSI standard, but is rather a method of sharing lamp system data. The Program provides a listing service in the form of publishing LCDs for public knowledge and for the development of standards. If there are multiple manufacturers of lamps operating with the same electrical characteristics, a standard may be proposed.
Once an LCD code designation is published in an ANSI approved C78 standard, the data can only be changed through the ASC consensus process. It is understood that the originating company releases all LCD data to the ASC WG2. The information in an ANSI standard for any LCD code supercedes the information on the code request form.
LCD data that is not in an approved ANSI standard may be changed only at the request of the original LCD requestor. To make such a request, the original applicant shall complete a LCD request form in its entirety and the “changed data” shall be distinctly marked. The box at the top of the Request Form labeled, "notification of change in design" should be checked. The Administrator shall, within 10 days of receipt, circulate the request to the Work Group 4 and the HID Lamp Code Designation participants for review and comment for a period of 30 days.
2 The method by which a Lamp Code Designation (LCD) becomes a proposed American National Standard (ANS) is outlined above. This is in lieu of a new paragraph.

7No new ANSI electrical characteristic number can be issued if the lamp is within the limits indicated except a new electrical number can be issued if the protection from rectification requirement is different from the existing lamp.
8The original lamp type has an associated lamp standard or is progressing towards standardization.
9 A retrofit lamp type(s) has a different lamp classification letter than the original lamp type and operates interchangeably on the electrical system including the reference ballast of the original lamp type within all the limits indicated.
10A new electrical characteristic number is required if the retrofit lamp requires rectification protection and the original lamp does not.
i M78-4/1453--#10.14.2: Scope of this LCD administrative project consists of two parts.
The first part is to revise the 1997 electronic form (4 pages long) presently in use to reflect what information is really essential to obtain a new lamps code for the newly approved 2002 standard. The proposed electronic form is intended to be published as a SR.
The second part is the proposed revision of the procedure steps cover under Section 7 of the ANSI C78.380—2002. The present Section 7 in the 2002 standard is the unchanged 1997 procedural steps. It pointed out that the program administrator is nothing more than a clerical administrative processing point for accepting, distributing and publishing LCD data in accordance with this standard. The substance of the LCD remains the responsibility of the applicant lamp manufacturing company.
