Eiki Projector Lamp Replacement: Full Model Index

Eiki projector lamps are usually coded either as an Eiki part number in the format 610-XXX-XXXX or as the Sanyo POA-LMP code for the same assembly, and both codes frequently appear on the same physical lamp. This is because Eiki and Sanyo shared projector platforms for many years, so a large part of the Eiki lamp range cross-references directly to a POA-LMP number. If you have one code and cannot find stock, search the other.

Eiki machines are built for institutional service life and a great many are still running in US schools, churches and auditoriums long after the brand's consumer visibility faded. Lamps remain the main maintenance item.

The two code formats you will see

• Eiki format: 610-XXX-XXXX — a six-digit service part number preceded by 610.
• Sanyo format: POA-LMPXX — the Sanyo lamp module code for the same assembly.

Both codes are often printed on the same lamp housing label. Neither is more correct than the other; they are two catalogues describing one part. This overlap is the single most useful thing to know when sourcing for an older Eiki, because availability under one code is frequently better than the other. See also our cross-reference guide and Sanyo projector lamps.

Finding your code

1. Check the label on the existing lamp module housing — usually both codes are there.
2. Check the projector model number on the rear or underside of the chassis.
3. Check the manual under specifications or replacement parts.

Work from the projector model if the lamp label is unreadable, which is common on lamps that have run for thousands of hours. See finding your projector lamp part number.

Replacing an Eiki lamp

1. Power off and let it cool for at least 45 minutes. Institutional projectors run hot and hold heat longer than small office units.
2. Locate the lamp door. On Eiki chassis it is usually on the side or the underside, secured by captive cross-head screws.
3. Release the bracket screws. Many Eiki modules are held by a small bracket rather than clipping directly into the bay. Keep the screws.
4. Withdraw the module along its rails using the handle. It should slide, not lever.
5. Fit the new module squarely and seat it fully so the connector engages. Never touch the quartz burner.
6. Refit the bracket and door, then reset the lamp timer in the projector menu.

Larger chassis, more airflow to maintain

Institutional Eiki projectors move far more air than a small office unit, and they pull far more dust through the filter as a result. On these machines, filter maintenance is not optional — a restricted filter raises internal temperature and shortens lamp life noticeably. Many Eiki chassis have more than one filter. Our air filter guide covers the routine.

Sourcing for discontinued models

Lamps for long-discontinued projectors get scarcer and more expensive over time rather than cheaper. If you maintain a fleet of older Eiki machines that are still doing their job, buying a spare lamp per machine while supply is good is usually the cheaper decision — and it avoids a hall being out of service waiting on a part.

Frequently asked questions

What is the part number format for Eiki projector lamps?

Eiki lamps use the format 610-XXX-XXXX. The same lamp very often also carries a Sanyo POA-LMP code, because Eiki and Sanyo shared projector platforms for many years.

Are Eiki and Sanyo projector lamps interchangeable?

In many cases they are the same physical part sold under two codes. It is not universal, so confirm the cross-reference against your specific projector model rather than assuming it.

Can I still get lamps for an old Eiki projector?

Often yes, particularly if you search under both the Eiki 610 code and the Sanyo POA-LMP equivalent. Availability tends to be better under one code than the other.

How do I reset the lamp timer on an Eiki projector?

The reset is in the projector's on-screen menu, generally under a setting or lamp counter section, and on many Eiki models requires a button combination on the control panel. Check the manual for your chassis, since it varies across the range.

Why does my Eiki projector have more than one air filter?

Larger institutional chassis move considerably more air than office projectors and use multiple filters to cover several intakes. All of them need cleaning, and a missed one still restricts airflow and raises lamp temperature.
