Type ET-16 and ET-17 Indicating Lamps

GE Power Management

INTRODUCTION

The ET-16 (incandescent and LEDs) and ET-17 (neon) indicating lam ps consist of a comm on receptacle, plug in
type resistors and lamps, escutcheon, and color cap. They are available for mounting on switchboard panels up to
and including ¼ inch thickness.

APPLICATION

These lamps can be used whenever a panel mounted signal or indicating lamp is desired.
The ET-16 is available for either one brilliance or dim bright operation when incandescent lam ps are used. ET -16

lamps are also available with Light Emitting Diodes ( LEDs). The incandes cent type can be easily upgraded to the
LED type. It only requires acquiring the appropriate color LED and lens cap and inserting into the lamp receptacle.

The ET-17 can be used when extra long life is a factor and brilliance is not. It also can be used when low current
is desired.

FEATURES

1. The simple “push-twist” type plug has been adopted for both the bulb and the resistor. This was
accomplished by incorporating a bayonet base on both components.

2. A common receptacle for both the ET-16 and ET-17 coupled with the plug-in resistor and bulb makes it
easy to change on the panel without disassembling.

3. The resistor is in series with the bulb, and the ohmic value for the differ ent circuit voltages is des igned at
80% of the rated bulb voltage to give it longer life. Changing voltages is easily accomplished by changing
the series resistor (see listed tables for the proper resistor).

GEH-3500F

4. A short circuit plug is available when a series resistor is not required or if an external resistor is to be used.

5. The ET-16 uses GE Catalog No. 1819 f or the 24 DC lam p and GE Catalog Num ber 1835 for the balance
of the ratings. For LED types, long life LEDs (100,000 hours) are specif ied. Additional features are as
follows: reduced heat, resistance to shoc k and vibration, improved safety, lower cur rent, c os t s avings , and
no cold filament inrush cur rent. The LED lamps come in red, green, and am ber colors. White is not an
option because a white light LED is not available. ET-17 uses GE Catalog Number B1A.

6. Terminals are readily available. They are designed for either AMP “FASTON” type connectors, solder, or
screws.

7. Nine basic color caps designed f or maximum visibility are available for ET-16 incandescent types. Five
Translucent caps: red, gr een, yellow, white; and four transparent caps: amber, red, green, blue, and c lear .
For ET-16 LED types, only the transparent lens caps are r ecomm ended. This is becaus e the transpar ent
lens allows more LED light to pass through than the trans lucent lens cap used on incandescent lam ps.
The available colors are as follows: red, green, amber, yellow smoke, clear and blue.

ET-17: Because of the special properties of neon, only amber, transparent red, and clear lenses are
suitable.

The color caps have a knurled OUTSIDE DIAMETER FOR EASY REMOVAL.

8. The ET-16 is also available for dim bright applications.

9. When special voltage or resistance is requir ed other than thos e lis ted, a s pec ial lamp may be ordered with
the proper design, or designated series resistor.

10. A two-inch ins ulating washer is supplied with each indicating light. It should be m ounted on the inside of
the panel as illustrated in Figs. 2, 3, and 4. The f unction of this washer is to provide additional insulation
between the terminal and ground (panel) if a surge were to be induced on one of the potential leads.

If a bulb other than those listed above is required, the lamp will be furnished less the bulb.
Listed tables give some of the specials made available.

RECOMMENDED PANEL ASSEMBLY

Thread the pal nut against the shoulder of the receptacle. Install the two-inch insulating washer on the front of the
receptacle against the pal nut. Insert the receptacle through the panel and thread the escutcheon nut against
panel. Install the color cap and hand tighten (do not force). Turn the escutcheon nut back up agains t the color c ap,
then back off ½ to ¾ turn (¾ turn recommended) to give at least 1/64 inch clearance but not m ore than 1/32 inch
clearance between the color cap and escutcheon nut (f or up to 3/16 inch panel). For the ¼-inch panel, the color
cap will be flush with the escutcheon nut. Tighten the pal nut against panel to 10 to 12 inch-pounds of torque.
