SSSS LCD Projector Replacement
Analysis Criteria
•
•
•
•
•
•
•
•
•
•
Minimum SVGA (800x600); preferably SGA (1024x768). SXGA will be expensive; do NOT want VGA (680x400)
1500 to 2000+ lumens
“Multipurpose” or conference room-type projector
Lower wattage bulb if available: last longer, stay cooler, more energy efficient
“Economy mode” desirable
Minimal f:number change at different zoom settings
All-glass lens will be better visual quality
Check replacement lamp costs
Additional useful items: USB Plug-&-Play; wide range of input types; remote; picture adjustment (manual or
automatic)
Initial investment between $500 & $1000
Boxlight replacement lamps: unsure of exact model, but everything I found online was $399 - $499 regardless of model.
