|Manufacturer||LimitlessLED / Futlight (other LEDs from LimitlessLED / Futlight)|
|Fitting Type||E27 (other E27 LEDs)|
|Review Notes||Claimed light source: 12x Samsung LEDs. Includes Digital Wireless 2.4GHz Remote. Claimed Replacement for 60W Incandescent. Eleven step incremental dimming using remote. Ten step increments from warm white to cool white using remote (3077K to 6016K). 0.2s start-up delay when turned on from power switch. Manufacturer specified Power Factor: 0.65. Bulb was tested on Step 6 on the 1 to 10 range of colors. Not compatible with standard wall dimmers. Dimming tested using remote. Dimming and CCT settings controllable via Android or iOS app connected via WiFi network with additional purchase of WiFi Receiver Bridge $17USD. Individual dual white bulb costs $14USD + remote $8USD. RGBW Color + Warm White version also available for $23USD. Similar white light capability and much cheaper alternative to Philips' Hue globe.|

Graph notes: Dimming performance can be highly dependant on the type of dimmer, the number of lights in the circuit and other factors. Results in your house might vary. Mouse over the graph for more details. Position 10 = Not dimmed. Position 1 = Fully dimmed.
Angle: 156° (±78° from bottom), Maximum lux:
Graph notes: Shows the intensity of the light when viewed from different angles. Normal omni-directional globes have a fairly constant output all the way around (excepting directly above). Downlights have a narrow range at the bottom in which the light is emmited, this determines their angle.
Graph notes: Shows the breakdown of the LED light into its component colors. With short wavelength ultraviolet on the left and long wavelength infrared on the right. The green line represents the relative absolute strength of the light at each frequency, while the red line represents what the typical human eye would see. The human eye is most sensitive to green light, but much less sensitive to purples and deep reds.
Percent: 1%, Index: 0.002 (lower is better in both cases)
Graph notes: Shows variation in light output over 1/10th of a second, with relative light output on the Y axis and time on the X Axis. Measured with a photodiode connected to an Oscilloscope. Ideally the yellow line should be flat. Low frequency high amplitude waveforms mean there is a possibility of noticeable flicker, but sensitivity to flicker varies between people.
