McKnight mounting and screen geometry

Existing installation

Screen sizeApproximately 11′10″ wide × 8′11″ high (roughly 4:3)
Calculated diagonalApproximately 177.5 in. / 14.8 ft
Estimated throw distanceApproximately 50 ft from projector lens to screen
Estimated throw ratio600 in. ÷ 142 in. ≈ 4.23:1
MountingLarge commercial projector mounted high at the rear of the auditorium, projecting forward to the main screen

What the 50-ft throw implies

Sharp offered multiple interchangeable lenses. At the estimated 50-ft throw and 11′10″ screen width, the required ratio is about 4.23:1.

  • AN-P30EZ: 3.0–4.5:1 — fits the current estimate and is the most likely range.
  • AN-P45EZ: 4.5–7.0:1 — would become plausible if the true throw is about 53.3 ft or longer for this screen width.

The installed lens model has not yet been positively identified. Before buying a replacement projector or lens, measure from the lens surface to the screen and record the lens model from its label.

Important replacement constraint: a normal fixed-lens 6,000-lumen projector is not a drop-in replacement at this mounting location. Any future projector should be an installation-class unit with an interchangeable long-throw lens and adequate horizontal/vertical lens shift.

Dual-lamp redundancy

How the two-lamp system works

Each Sharp XG-P610X-N contains two AN-P610LP lamp assemblies. These are two internal lamps feeding the projector's single projection lens—not two projection lenses.

Sharp provides several Lamp Mode settings:

  • Lamp 1 Only: Lamp 1 is used normally; if it fails, Lamp 2 can automatically take over.
  • Lamp 2 Only: Lamp 2 is used normally; if it fails, Lamp 1 can automatically take over.
  • Both Lamps: both lamps operate together for maximum light output.
  • Equal Use: the projector alternates usage to balance lamp hours.

Why this matters at McKnight

For Sunday worship, the single-lamp modes provide useful built-in redundancy. If the active lamp burns out during service, the projector can continue using the second lamp rather than immediately losing the main screen.

Recommended documentation step: verify and record the current Lamp Mode on both McKnight projectors under Options 2 → Lamp Mode. If the main projector is set to Lamp 1 Only or Lamp 2 Only, document which lamp is primary and which lamp is acting as the backup.

The backup behavior depends on the Lamp Mode setting, so the second lamp should not be described as an automatic backup unless one of the single-lamp modes is actually selected.

Replacement lamp / bulb information

Sharp specified part

AN-P610LP

Sharp specifies this lamp unit for the XG-P610X / XG-P610X-N. Each projector uses two lamp modules.

280 W lamp; approximately 2,000 h normal / 3,000 h Eco.

Genuine / original-bulb market

True Sharp-branded new-old-stock is now scarce because the projector is discontinued. Historical Sharp list pricing was about $549 per lamp module. Current “original bulb” specialist listings can still be around the high hundreds depending on stock.

For an 18-year-old projector, paying very high NOS OEM pricing may not be economical.

Current compatible pricing

iFixit: about $129.99 per AN-P610LP lamp + housing (current listing).

ProjectorLamps.com: XG-P560W/AN-P610LP family “genuine original bulb” listing around $186.

Low-cost aftermarket: listings can be near $61, but quality can vary.

Suggested McKnight inventory: keep at least two known-good complete AN-P610LP lamp modules on hand; four modules would provide one full matched set for each projector. A reasonable quality-replacement budget is roughly $260–$750 for two to four lamps, depending on supplier and whether the lamp contains a genuine/original bulb.

Sept. 28, 2026 troubleshooting record

  1. Both the main and spare projectors had experienced lamp-related problems after previous lamp replacement attempts.
  2. One unit displayed a blinking red LAMP 2 indicator and would not operate normally.
  3. The lamp compartment was inspected. Lamp 1 was difficult / unable to be removed from one projector; Lamp 2 was removable and became the focus of testing.
  4. Replacement modules on hand were labeled AN-P610LP but appeared to be aftermarket assemblies rather than clearly Sharp OEM assemblies.
  5. Lamp 2 was removed, reseated/replaced, and its lamp-hour counter was reset using the projector control-panel reset procedure.
  6. After continued troubleshooting, one projector was successfully returned to operation.
  7. The spare should still be repaired and then tested long enough to confirm it is a dependable backup.

Original purchase / replacement value context

Estimated original system cost

The XG-P610X-N carried an original MSRP of approximately $13,995 without a lens. A suitable AN-P30EZ long-throw lens historically listed around $3,095, and Sharp's ceiling bracket was historically about $395.

That puts a rough 2008-era list-price equipment package near $17,500 per installed projector before cabling, lift/access, labor and dealer discounts. McKnight's actual purchase price is not currently documented.

Long-term replacement planning

Because these projectors are now roughly 18 years old, significant electronic repair should be weighed against replacement. A modern 7,000–8,000+ lumen laser installation projector with a long-throw lens is the appropriate class.

A planning allowance of roughly $9,000–$15,000 for projector + long-throw lens remains reasonable, subject to exact measurements and dealer quotes.
