Remez luminaires with solar spectrum

The Remez brand, known for the world’s first LED lamps with a solar spectrum, produces not only lamps, but also luminaires with the same SunLike LEDs. I have tested three models.

The luminaires are equipped with Tuya-compatible Wi-Fi / Bluetooth modules and can be controlled from the smartphone app (you can use both the proprietary Remez Smart Light app and the Tuya or Smart Life apps). Ceiling lights are also controlled by the included remotes.

All luminaires are dimmable, and ceiling luminaires also change their color temperature from warm to cold.

Lamp Leda looks unusual in photographs.

The light of each LED turns into a beautiful volumetric luminous figure.

The lamp is a plastic ring with a diameter of 50 cm.

The declared parameters: power 60 W, luminous flux 100 – 4000 lm, color temperature 3000-6500 K, CRI color rendering index (Ra)> 95.

The luminaire contains LEDs of two color temperatures: “warm” and “cold”; by mixing their light, intermediate color temperatures are achieved.

I tested the lamp in three modes: warmest, neutral, and coldest.

The spectrum in all modes is flat, corresponding to the SunLike spectrum, the color rendering index is very high – 97-98. There is practically no light ripple, both at full brightness and when it is reduced. The color temperature of the “warm” LEDs is 3000K, and the color temperature of the “cold” ones is about 5500K.

The power in different color modes varies from 57 to 60.6 watts. Taking into account the average efficiency of Sunlike LEDs of 67 lm / W, the luminous flux of the luminaire in warm light mode is about 3800 lm, in neutral and cold light modes about 4100 lm.

In the mode of the minimum brightness of warm light, the luminous flux of the luminaire is 4% of the maximum.

When the light is turned off in the app or from the remote control, it draws about 0.4W.

The remote control is infrared, the buttons glow in the dark.

There are on-off buttons, off after 30 seconds, selection of three color temperatures (warm, neutral, cold), minimum and maximum brightness, in addition, brightness and color temperature can be changed by smoothly pressing the central ring.

The luminaire remembers its state after power off. With an ordinary switch (in fact, by a short-term power outage), you can change the color temperature (warm-neutral-cold).

This is how the luminaire body looks from the back.

The luminaire has a limited illumination angle and does not shine back at all. This leads to the fact that the ceiling and corners of even a small room remain dark, and the center is brightly lit. For those who prefer uniform lighting, additional lighting may be needed around the perimeter of the ceiling or in the corners of the room.

Second ceiling light Wisper has a diameter of 60 cm.

The declared parameters: power 50 W, luminous flux 100 – 3300 lm, color temperature 3000-6500 K, CRI color rendering index (Ra)> 95.

The results of my measurements in three modes.

The spectrum is the same even, the color rendering index is very high – 96-98. There is also no light ripple in all modes. The color temperature of the “warm” LEDs is 2800K, and the color temperature of the “cold” ones is about 5100K.

The power in different color modes ranges from 44.5 to 47 watts. Luminous flux in warm light mode is about 3000 lm, in neutral and cold light modes about 3200 lm.

In the mode of the minimum brightness of warm light, the luminous flux of the luminaire is 4% of the maximum.

When the light is turned off in the app or from the remote control, it draws about 0.45W.

The console is using a radio channel.

There are buttons for selecting a color temperature, turning off after 30 seconds, three brightness modes (minimum, quarter, two-thirds), on and off buttons. The maximum brightness is set by switching the color temperature. There is a possibility of smooth adjustment of brightness and color temperature using the buttons of the central ring.

Like the first luminaire, the Wisper has a limited illumination angle and does not illuminate the ceiling.

The luminaire consists of a ceiling module and a flat block with LEDs, suspended on cables-wires.

The declared parameters: power 40 W, luminous flux 100 – 3150 lm, color temperature 4000K, CRI color rendering index (Ra)> 95.

The results of my measurements.

The spectrum is excellent, the color rendering index is almost 99. There are no ripples. The color temperature is about 3900K.

Power 38.1 W. Luminous flux about 2550 lm.

In the mode of the minimum brightness of warm light, the luminous flux of the luminaire is 1% of the maximum.

When the light is turned off in the app or from the remote control, it consumes about 1.5W.

Whenever turned on (by switch or from the app), the light turns on smoothly. When turned off from the application, there is a smooth fading out.

The luminaire can be used both for general lighting in a room with high ceilings (most likely several of these lamps will be needed), and for local lighting when placed above a table.

This is how the luminaire control interface looks like in the application.

I made a short video about Leda, but Wisper got into it too.

Remez luminaires, thanks to the use of Sunlike LEDs from the Korean company Seoul Semiconductor, provide the most comfortable and safe light with an even “solar” spectrum.

Ceiling luminaires have a limited illumination angle and do not illuminate the ceiling, therefore additional illumination may be needed to evenly illuminate the room.

The parameters of the luminaires are close to those stated. Thanks to the ability to change the color temperature of the ceiling lamps, you can adjust the light so that it is as comfortable as possible for everyone. Smart functions allow you not only to control lamps from the application, but also using voice assistants, but also to set up scenarios, in particular, to change the color temperature of lighting throughout the day.
