Master LED 5.5W MR16 Review
General Information
| ID | #284 |
|---|---|
| SKU | N/A |
| Series | MASTER LEDspot |
| Manufacturer | Philips (other LEDs from Philips) |
| Fitting Type | MR16 (other MR16 LEDs) |
| Light Type | Downlight (PAR) |
| Height | 42mm |
| Diameter | PAR16 (50mm) |
| Weight | 44g |
| Warranty | 5 Years |
| Test Date | 2014-06-10 |
| Review Notes | Non-dimmable. Carries RCM and CE approval label. More efficient and similar lumen output to Philips' 7W dimmable MR16 from the same series. Excellent power factor. Good CRI and lumen output for it's price. This is the highest-scoring non-dimmable MR16 tested here to date. We wouldn't normally suggest using a MR16 fitting for LEDs, but if you do want a MR16, this is one of the better options. |

Distribution Graph
Angle: 66° (±33° 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.
Spectrum Graph
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.
Flicker Graph
Percent: 3%, Index: 0.003 (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.
