Brightness and colour of “Varilux” you can with a simple wireless remote-control LED lamps “LightMe”. The system is simple, requires no additional peripherals such as Wi-Fi or Smartphone and offers as a very low threshold in the “Smart lighting ‘ world.
Infinitely remote LED light with variable brightness and color temperature do you know so far mainly of relatively complex systems such as Philips “hue” or”Lightify” OSRAM. Sometimes there is but also as a ‘ stand-alone ‘ solution withBluetooth, radio or infrared remote controls.
Many “average Joe” want or need but no advanced technology with countless programming and Automation apps – instead as easy access to the most important functions is sufficient. This target group wants to use the IDV brand “LightMe” with their “Varilux” series.Which currently only consists of two products: A Starter Kit with 6.5 watts of strong E27 LED bulb and 2.4 gigahertz – wireless remote (without batteries, EIA €34.95, online partly even considerably cheaper) as well as the “Pear” solo as freely scalable expansion (MSRP €14,95).
Within the radio range of up to 30 meters, as many lamps can be connected to four groups into three – and controlled; a lamp can be paired with up to four remote controls. per FB it assignable to one of four groups. Conventional dimmer must be connected not with the “Varilux” lamps – just normal switches are allowed.
Lamps note the selected setting
The light colour selected previously via FB and brightness setting is not lost by the turning off and on.Theoretically you could set so a fixed lighting scene, the remote control (links, photos: W. Messer) lock and use only the wall switch.
That would deprive you but the flexibility of the system itself (below the back of the Pack): infinite dimming between 100 and 10% of the maximum nominalluminous flux of 470 lumen (control buttons up, down), of independent, continuous change of colour temperature between approximately 2700 (“warm white”) and 6500 Kelvin (“cold white”) with both left and right buttons.
In addition, there is a “night light” function with approx. 2% brightness and preset “cold white” light color. Here a much “warmer” tone seems appropriate but. Who needs already industry emergency color temperature at home – in the middle of the night?
Largely confirms Watts details
My hobby gauge showed an amount of consumption over the dimming range between 1.2 (for all temperatures) and 6,0 (“neutral white”), 6.1 (“warm white”) and 6.9 Watts (“cold white”) after two hours of steady – with a maximum electric power factor of 0.62.Arguably the highest lumen is achieved with this setting, which roughly corresponds to the brightness of a conventional 40-watt light bulb.
In my offenenen, hanging test version, the lamp at this point to 61 degrees at the top,hottest Housing Authority and maximum 26 degrees at the bottom of the hood heated up. The “night light” moved around 0.8, “Standby” up to 0.6 Watts; It developed no appreciable heat.
Not a perfect round spotlight, but still OK
The normal desk there was a delay of some less than one second; It was completely dark within a scant half-second after switching off. With the FB-switch which reversed largely: about 0.5 seconds of thinking time when switched on, hide in about one second.
The half value angle is not known “LightMe” Unfortunately, should be based on the lamp type and my light pictures at around 200 degrees but – for many applications this is sufficient “round”. I can not offer this time unfortunately exact measurements from the lab, because my master technicians resides until the end of the month in the well-deserved vacation. As illustrative examples I the “warmest”, medium and “coldest” color temperature lamp photographed (from left to right):
Light quality for many areas of application sufficient
Is the color rendering index RA > 80 estimated, might change slightly but, depending on the light color. In principle offers the “Varilux” lamp at least an acceptable quality of light, as well as the two fidelity images with my standard model show 916 in miniature against a white background – a site Ducati. Left there from above around 2700 Kelvin, right 6500 K (white balance “cloudy”, without post processing):
The colors are well identifiable and distinguishable; the “warmer” settings also reasonably suitable for human skin tones and the assessment of makeup experiments. Unpleasant color casts are not noticed. However, the display showed a slight flicker, which was confirmed also by the “Flicker Tester” app my digital camera (right screenshot).
The index by 0.1 and the rate of 28% are not really dramatic – especially since the rule frequency apparently is a very high range of several kilohertz, which may not consciously be perceived also by sensitive eyes. A modern IC switching regulator is probably responsible.
Faint whirring at lightest settings
Disturbed another phenomenon could affect, which must not, however, occur at each (see comments below): silent environment buzzed the activated lamp something audible at distances between 5 (dark setting) and 30 cm (brightest control). I would not use therefore prefer the “Varilux” in a night table lamp near the pillow; Maybe she’s in your house power supply but also quiet.
Not much to expose there on the efficiency of about 72 lumen/Watt (EU eco-label A + with consumption rounding up to 7 kWh / 1000 hours, Pack snippet links) and the nominal lifetime of 25,000 hours of light, as well as 40,000 cycles. The latter figure is probably rather carefully conservative.
My test result:
Flexible and from a distance of up to 30 meters the brightness and colour temperature of LED light bulb change – without sophisticated programming, sensors, Georefenzierung, Smartphone, Tablet, Wi-Fi and / or Internet: technology lovers would probably ignore that as “Kid stuff”. “LightMe” but has”Varilux” other users in their sights: for example, families with children, seniors, singles and couples without special Smartphone game drive.
You get a relatively simple system in hand, that there are also used in some hardware stores and should be supplemented with other types of lamps for Less than 35 Euro. So far the offer is unfortunately still somewhat thin and limited to E27 sockets -“Pear” with 89 grams of weight, length 114 mm, 60 mm maximum diameter and nominally 470 lumens, which offers just that in my opinion, however no longer promises “LightMe” -. Light “Gourmet”, for the LED lamps only start 90 half value angle color fidelity values from RA to 300 degrees, and need to shop elsewhere. For my strict LED scale gives solid
