The back side of the device features a cluster of LED lights.
I've replaced my old lights with LEDs and made my own up-lighters that use clusters of LEDs.
Light output from clusters of LEDs were channeled into columns of slits under user-control, generating moving stripe patterns, whose speed, intensity and horizontal width could be altered during the experiments.
According to Newlaunches.com, "It houses a cluster of coloured LEDs and optical fibres that form a screen.
Now, is Google+ simply leading the charge to replace your bulb with a stylish cluster of red LEDs?
Blue-light irradiation of yeast cells was performed using custom-build sets of light-emitting diodes (LEDs): high power LED stripes (18 LEDs, 465 nm; revoART, Borsdorf, Germany) or StrawHat LED clusters (6 clusters of 42 LEDs, 465 nm; revoART, Borsdorf, Germany); both sets were equipped with a dimmer to select an appropriate light-flux.
To compete with the light output of a single 60-watt incandescent bulb that emits about 800 lumens (a measure of light power as perceived by the human eye), companies such as LED Lighting Fixtures and Permlight of Southern California are designing lamps based on clusters of white LEDs that achieve a similar lumen output, but consume a fraction of the power.
Crystal irradiation was performed using a cluster of seven UV LEDs (400 nm) placed 8 mm above the sample.
Obesity and clustering markedly increased the likelihood of LEDs in this sample and identified a group for whom preventive activities may reduce the risk of future disability.
Blue LEDs can be combined on a cluster with other LEDs to give all colours, including white, for full-colour moving displays.
Even after the exclusion of individuals with diabetes, results for the associations of LEDs with cardiometabolic clustering-obesity phenotypes remained virtually unchanged for peripheral neuropathy alone and PVD alone and only slightly attenuated for the combination of both peripheral neuropathy and PVD.
