How many lumens do you need to see projection in the daytime? Pro-test new nuts L6_H projector

Exterior

Throw away the packaging straight to the topic! Nuts L6_H does not use too many fancy elements in the design of the product appearance. The large lens with a square body is a little traditional business style. However, in the production process and full touch operation is still "sold out" of its unusual, silver casing presents a metallic color, especially the upper cover uses a spiral drawing process, metal texture is full, so that the product as a whole becomes even more a sense of future technology .

The highlights of Nut L6_H are quite numerous, the most attractive of which is the 3500 ANSI super high lumens, and 1080P physical resolution is also the current HD standard. Other features such as automatic focusing, trapezoidal correction (up and down ± 45 °, left and right ± 45 °), independent Bluetooth speakers and so on also add to the performance of the projector.

Nut L6_H uses a highly transmissive all-glass lens. As we all know, all-glass lenses have better light transmittance and heat resistance than resin lenses. They are the material of choice for projection lenses. In precision optical instruments, the introduction of resin material has greatly reduced the cost, but the problem of the resin is also obvious. In the imaging, the distortion and edge sharpness control are not as good as the glass material. A lens, especially a projection lens that is often subjected to high-temperature baking, uses a large number of resin lenses not only results in a poorer image quality than a full-glass lens, but also makes it difficult to play the virtual focus for a while, so it is recommended that during the purchase of the projection, The all-glass lens can be used as a mandatory option, which can eliminate lens defocus, ghost focus, and run out of focus.

According to current ultra-high pressure mercury bulb technology, high lumens means that high heat is generated at the same time. The problems of heat dissipation and noise suppression have always been difficulties encountered by high lumen projectors. The nut L6_H adopts a symmetrical air outlet design to make the heat dissipation more efficient, promote the internal air duct diversion, and cooperate with high-power turbofans and large air outlets to achieve noise and heat dissipation. The light that was lost inside was not wasted, and the cold light of the projection was used to create a bright and dark three-dimensional light hole. The effect was soft and not dazzling, and played a very good decorative effect.

The light source uses OSRAM brand ultra-high pressure mercury bulbs, made in Germany, the advantage is long life, often used in high-end projectors. The bulb is nominally rated for maximum power and can accumulate over 4000 hours. This data is quite satisfactory, but it is also very sincere. Many bulbs marked over 10,000 hours actually contain time after the brightness has significantly decayed.

The Lens L6_H lens also has an optical zoom function with a zoom ring at the top of the lens and supports 1.2x manual zoom. This function is very suitable for changing the size of the projected image without sacrificing the pixels without moving the body. For a common fixed-focus projection, it is equivalent to one more lens and can be used for more use scenes.

All the physical interfaces of the nut L6_H are centrally designed on the backplane of the projector. These interfaces include S/PDIF audio interface x1, USB2.0x1, USB3.0x1, HDMI interface x2, Ethernet interface x1, and one for technical maintenance of the manufacturer. The service interface. Abundant interfaces can meet common device connections, use these interfaces to achieve more application requirements, and full coverage of office entertainment. For example, the USB interface can be connected to input devices such as mouse and keyboard for game and document presentation. USB3.0 interface and HDMI interface make it easier to play super clear content on external devices.

The shape of the remote control is still continuation of the nut features, fewer buttons, simple and practical functions. The curved infrared emission window has a good remote control range. In use, the remote control can be smoothly performed in the room as long as it does not block the emission and the projector receiver. In addition to using the original remote control, the Nut L6_H projector, like many smart devices, can also be controlled using the mobile phone APP, making it more flexible and convenient in terms of control.

The nut L6_H projector has a 1/4 international standard screw hole for attaching a tripod at the bottom and an M4 normal screw hole for fixing the lifting bracket. The projector's own body weight is 2.5 kg, and the center of gravity is centered. This ordinary tripod and lifting bracket can support stably.

Bluetooth speaker experience

Among the many highlights of the Nut L6_H projector, the Bluetooth Independent Speaker is a delightful design. The speaker can be used when the projector is in a standby state, ie, the power supply is free from listening to music after being powered on. The audio source is only a multimedia device with Bluetooth. The hardware configuration of the speaker belongs to the desktop high-quality level, built-in 5W * 2 symmetrical speaker, independent three-frequency dynamic tuning. Personally think that the output sound quality has a great relationship with the sound source, as the latter nut L6_H performs differently under different input sources. In general, the bass is heavy, the high sound is transparent, the sound is resistant to hearing, and the effect is satisfactory.

Projection experience

The reason why this projection is of interest is because 1080P full HD +3500 ANSI lumens, super high lumens to see the video in the "light day of the sky" is to start its purpose. Here we use this wall as a curtain to perform the projection experience. Although the visual effect is not as good as that of a professional curtain, if the projection brightness can achieve the purpose of viewing the movie, it proves that its high lumen is true.

Before the official projection, the brightness contrast is compared. The left eye of the figure below is a 1000 ANSI lumen projection effect of a certain LED projector, and the right eye is a 3500 ANSI lumen projection effect of a nut L6_H projector. The brightness of the environment is a dark room interior with a 24Wx6 Philips energy-saving lamp set. The brightness of the photo is close to what the naked eye actually sees. The eye picture is the same copy. According to the figure, the brightness of the right eye is higher than that of the left side, the proportion is faithful to the original picture, and the details are rich, the sharpness is higher, and the overall picture quality is obviously better than the image shot by the left projector.

Keystone correction

To reach a 150-inch delivery size, the projector needs to be 5 meters away from the wall. Because the width of the living room is not enough, the projector can only be placed diagonally. The position of the camera in the picture is the position of the projector. At this time, the image obtained on the wall surface is not correct, and the angle of the inclined surface exceeds the range of automatic correction. The image needs to be corrected by the user. With the vertical and horizontal ±45° trapezoidal correction function of the nut L6_H, it is convenient to realize this special angle projection.

The effect of the 150-inch giant screen is that the tens of inches of LCD TV can't bring about, and it can reach the 70% shock of the cinema. The following figure shows the effect of turning off the lights in the dark room. The visual effect is basically equal to the LCD TV! At the same time, the diffuse reflection of the projected light illuminates the room to create a better viewing environment. This diffused light can protect the eyes compared to the direct light of the TV.

Day-to-day viewing has always been the goal of the projector, and the nut L6_H is no exception. Here's a look at how a projector with 3500 ANSI ultra-high lumens can pull down curtains and watch movies in the sun.

This is the weekend morning, the winter sunshine is not dazzling, the interior light is soft. This kind of ambient light is very obvious for low-lumen projectors. It cannot be seen without pull-out curtains. The so-called projection "sees dead-light" is also derived from this. The following figure shows that the 3500 ANSI super high lumens of the nut L6_H projector breaks the bottleneck of the projection “seeing dead”, and the white wall and black characters show clearly.

Automatic focusing + 1080P physical resolution, so that the picture is more clear, relative to the dark environment, this time the picture clarity by the external light interference becomes lighter, close to the window position is more obvious, but still can see the details.

In color and picture quality, the nut L6_H projector uses DLP display technology, square pixel distribution, layering is better than the previous diamond-shaped pixels, the edges are soft, the overall picture is more moist.

System Experience

The smooth system experience is inseparable from the high-speed and stable network connection and hardware support. The nut L6_H projector uses 2.4G/5G dual-band WiFi in the wireless network connection, and the compatibility is better. The ultra-clear video is not played with 5G WiFi. Secondly, the system adopts self-developed JmGO OS. This system is based on deep optimization of Android. It is the simplest to use, and the clear functional areas make it easier for users to get started.

In terms of content, iQiyi covers more than 95% of the new movies in the domestic theater line. If it is a VIP member, it is almost impossible to download videos on the PC. There are almost all of them here. The embedded iQiyi is a wise move for the Nut L6_H projector. Here is the paradise of the drama. The timely update makes people unable to stop.

Education applications are also integrated in the system. These applications are suitable for children and adult ages. There are abundant teaching resources and many of them are free applications. Here, you can teach children of different ages some supplementary teaching, or you can charge yourself. All kinds of teaching videos can be easily found. Even Yale University's teaching videos can be opened with you.

Wireless screen is a kind of fun for the mobile phone to enlarge the screen. To download the audio screencast assistant on the mobile phone side, you need to pay attention that the mobile phone and the projector need to connect to the same WiFi. After a simple two-dimensional code scan, you can achieve the same wireless screen. The same screen has a delay of less than one second, and the time is very short. This is acceptable in practical use. The connection is stable, and the game that has been tested for more than ten minutes is not disconnected and the picture is smooth.

Not just ordinary video playback, nut L6_H projector also supports 3D playback, active shutter 3D technology, just wear matching 3D glasses to watch! Unfortunately, this 3D effect cannot be captured by a lens camera. In addition, the Nut L6_H projector can also use the remote controller to play games. There are many remote control games that can be installed based on the Android system. Several of them have been tested in the “Dangbei Market” and they can perfectly support the projection of the big screen. The experience is very good! You can also use the two USB ports on the backplane to connect gamepads. It's a good idea to play double-doubles with this giant screen, but be careful to be too close to the screen to be dizzy.

The larger the projection screen size, the greater the effect of external light on the projection effect! This is caused by the attenuation of light energy, and reducing the size of the delivery will increase the brightness of the screen. When the screen is reduced to 80 inches, the brightness of the screen suddenly increases, and the midday sun that shines through the window can still perform well. Even ordinary walls can achieve day-to-day viewing.

The projection is not limited, whether it is the projection angle or the face of different ambient light, better adaptability is the best experience to use the projector. The nut L6_H performed satisfactorily in these two aspects. The reason is that the 3500 ANSI high lumens play a major role. No matter which projection, the current projection technology does not have high lumens and it is difficult to achieve the normal daytime experience. effect.
