How much power does a 120 inch projector need?
えい ほうAs a projector manufacturer that expands the possibilities of home entertainment, Aestiquo often receives the question, "How much power supply capacity is required for a 120-inch projector?" The "power supply capacity" here actually refers to ANSI lumens (luminous flux), and the appropriate value varies depending on the screen size and room brightness.
According to a survey by the Japan Electronics Manufacturers' Association (JEMA), 2000 to 3000 ANSI lumens are recommended for comfortable viewing on a 120-inch TV, but there are some tips on how to choose the right one.
Selecting ANSI lumens to suit the brightness of your room
Dark environment (cinema-level darkness): 2000 ANSI lumens
In a well-lit room, 2000 ANSI lumens provides sufficient brightness and contrast.
The Aestiquo P1 's 2000 ANSI lumens are ideal for this, delivering deep blacks and vibrant colors, ensuring even the finest details in dark areas are clearly reproduced when watching movies at night.
Semi-bright environment (indirect light from hallway lights or windows): 2500 ANSI lumens
For use in dimly lit bedrooms or living rooms, 2500 ANSI lumens is recommended.
The Aestiquo Q1 's 2500 ANSI lumen model maintains clarity without washing out the screen even in rooms with indirect light.
Bright room (living room or office during the day): 3000 ANSI lumens
Rooms with direct sunlight coming through windows require 3000 ANSI lumens or more.
In this case, combining it with Aestiquo 's hybrid projection screen will reduce reflections and ensure brightness.
ANSI Lumen Calculation Formula: Knowing Your Actual Luminance Needs
Required brightness (ANSI lumens) = Recommended illuminance (cd/m²) x Screen area (m²)
Example: The screen area of a 120-inch (16:9) is approximately 2.6 m2
Recommended illumination in dark environments: 750 cd/m² → 2.6 × 750 ≈ 1950 ANSI lumens
→ 2000 ANSI lumens is appropriate.
Aestiquo P1: 120-inch optimal solution for dark environments
The Aestiquo P1 is equipped with 2000 ANSI lumens and is renowned for its ability to reproduce dark areas at 120 inches.
Equipped with Android TV 13.0 and a 270-degree rotating stand, it supports various installations, including ceiling and wall installations. It also supports 4K and can project up to 350 inches on a large screen, making it ideal for watching movies and sports.

Summary of points to consider when selecting brightness
- Measure your room's brightness : Check the light level with a light meter app and choose from 2000-3000 ANSI lumens.
- Check the throw distance : The Aestiquo P1 achieves 120 inches at 3.5m, so adjust it to suit the size of your room.
- Combine with a curtain : In bright rooms, use a high-contrast curtain to compensate for the lack of brightness.
