GE 35800 EKP/ENA

GE 35800 EKP/ENA — Quartzline® Multi-Mirror® MR16 80W 30V Projection Lamp, GX5.3 Base, 3350K

The GE EKP/ENA (order code 35800) is an 80W 30V Quartzline® Multi-Mirror® MR16 halogen projection lamp with a GX5.3 two-pin base and a CC-6 filament. It runs at a colour temperature of 3350K with a rated life of 25 hours and a typical lamp working distance of 1.75 in. The lamp measures 1.750 in maximum overall length by 2.000 in diameter. GE lists its primary application as 8mm slide projection. Burn position is restricted to horizontal ±15° or base down. This is a pressurized halogen lamp and must be operated in an enclosed fixture rated for it. Confirm the ANSI code, base, working distance, and burn position against the equipment before ordering.

Availability notice: GE lists this product as no longer manufactured. Remaining stock will be sold. Contact ADL Supply to confirm current availability before specifying it for a project or planning ongoing spares.

Technical Specifications

Product Overview

Projection lamps are precision optical sources. Unlike general lighting lamps, they are built with tailored filaments positioned to close tolerances so the light source sits exactly where the equipment optics expect it. That is why working distance and burn position appear on the specification alongside wattage and voltage: a lamp with the right base and wattage but the wrong filament position will not focus correctly.

This is a GE Multi-Mirror® lamp — a halogen Quartzline® filament tube combined with a faceted dichroic reflector and assembled to a rim reference, so the lamp snaps into alignment on installation rather than needing adjustment. The dichroic coating passes infrared rearward through the reflector instead of forward with the beam, producing a cool beam that reduces the heat load on film in the optical path. The faceting delivers an efficient, uniform beam with precise control. The typical working distance of 1.75 in is the distance from the reflector rim to the film plane in the optical system this lamp was designed for.

The quartz envelope and halogen fill cycle return evaporated tungsten to the filament, so the bulb does not blacken or blister as an ordinary incandescent lamp does, and output and colour temperature stay effectively constant across the life of the lamp. Rated life is 25 hours, which is normal for a projection lamp of this class where source brightness and optical precision take priority over service interval.

Burn position matters on this lamp. It is rated for horizontal within ±15 degrees or base down. Operating outside that range shortens life and can cause early failure, because the halogen cycle and the mechanical support of the filament are both designed around the intended orientation.

EKP/ENA is a multiple-ANSI-coded lamp. GE assigns several ANSI codes to some projection lamps for customer convenience: the first code, EKP, is the ANSI code and the one marked on the lamp itself, while the secondary code identifies a lamp this one directly replaces. Equipment calling for either EKP or ENA can take this lamp.

Compatible Applications

• 8mm slide projection (GE listed primary application)
• 8mm and slide projection equipment
• Microfilm and micrographics equipment using MR16 projection lamps
• Optical instruments requiring a 1.75 in working distance
• Replacement lamp for equipment specified with ANSI code EKP
• Direct replacement for equipment specified with ANSI code ENA

Before Ordering — Verify

• Confirm current availability. GE lists this product as no longer manufactured and remaining stock will be sold. Do not specify it for an installation requiring ongoing replacement supply without confirming stock.
• Confirm the equipment calls for ANSI code EKP or ENA. ANSI codes assure mechanical and electrical interchangeability between manufacturers, so this is the primary cross-reference.
• Confirm the socket is GX5.3 two-pin.
• Confirm the supply is 30V. This is an unusual projection voltage and is not interchangeable with 12V, 21V, or 24V MR16 projection lamps that share the same base.
• Confirm the required working distance is 1.75 in from the reflector rim to the film plane.
• Confirm the equipment accommodates a 1.750 in maximum overall length by 2.000 in diameter lamp. Listed lengths include maximum tolerances, so actual lamps are generally slightly shorter.
• Confirm the equipment holds the lamp horizontal within ±15 degrees or base down.
• Confirm the fixture is an enclosed type rated for this lamp. This is a pressurized halogen lamp and must not be run in an open fixture.
• Note the 25 hour rated life when planning spares. Rated life is a laboratory median at rated voltage, not a service life guarantee — shock, vibration, voltage fluctuation, and temperature can all shorten it.
• Confirm package quantity — this item is supplied as a bundle of 20.

Safety and Handling Guidelines

• Turn power off before inspection, installation, or removal. Risk of electric shock.
• Allow the lamp and fixture to cool before handling. Risk of burn.
• Turn power off before installing the lamp.
• This is a pressurized lamp. Unexpected rupture may cause injury, fire, or property damage. Use only in an enclosed fixture rated for this product.
• Avoid direct water, liquid, or metal contact with the lamp.
• Do not exceed 110% of rated voltage.
• Do not use the lamp if the outer glass is scratched or broken. The lamp may shatter and cause injury if broken.
• Dispose of the lamp in a closed container.
• Keep combustible materials away from the lamp. Risk of fire.
• Do not touch the quartz envelope with bare hands. Skin oils cause localized overheating of the quartz and can lead to premature failure or rupture. Clean with isopropyl alcohol if the envelope is touched.
• Observe the horizontal ±15° or base down burn position restriction.
• Ensure the equipment provides the cooling airflow it was designed with.
• This lamp contains no mercury. Recycle or dispose of it in accordance with local requirements.

Compliance

• Refer to GE's published cautions and warnings for this order code before specification or installation.
• Contains no mercury. Not subject to mercury lamp disposal or shipping restrictions.
• Rated life is stated per ANSI standard design life.
• Dispose of in accordance with local regulations.
