Comparison of LED lamps by Philips and CREE

led-lamp-100w-0

In this review we will be comparing LED incandescent counterparts at 100 watts.Measurements and photos made counterpart, the foreign electronics lover. They provide high levels of light flux.

Test samples are full analogues of the usual 100 watts and provide 1600 lumens, even with the stock, and I think their standards of quality LED lamps for the home. Many other manufacturers, half of them from China, taking advantage of low awareness of buyers, with luminous flux 900-100 lm write that they replace incandescent lamp 100W. A renowned manufacturers such do not, the quality and integrity above all else.

The parameters of the test samples

Here are the declared parameters. Socle they can be not only E27, E26 and oriented at an American size.
In high foreign standards, such as the Amazon store,
It is believed that:

  • LED analogue to 75W = 1145 lm, 15W;
  • analogue 100W = 1600 lm, 19W

Philips Ambient LED Household A21

  • luminous flux of 1620 lumens;
  • consumption lamp power 19W;
  • the color temperature of 2700K;
  • color rendering CRI 81;
  • price of $ 22.

CREE 100W LED bulb

  • power consumption 18 watts of electricity;
  • brightness of 1600 lumens.
  • the color temperature of 2700K;
  • CRI 81.

To measure power consumption and current no special meaning, such popular manufacturers always accurately indicate the specifications of LED lamps .

Measurements of the spectrum of light

To measure used spectrometer UPRtek MK350 and software MoreSpectra.The graphs presented in intensity depending on the wavelength of light that is the color.For clarity on the graph plotted colors themselves.

For a visual test and facilitate comparisons use the box for photography.Light Warm white light, but the photo was used white «incandescent lamp» balance that compensates for the yellowing of light.

Since they are equal in terms of technical specifications, it is comparable to other types of Cree, ordinary energy-saving and incandescent 200 watt.

Test with an incandescent lamp 200 W Test with an incandescent lamp 200 W

We compare the brightness CREE to 100W with other of the same manufacturer and the same series. From left to right:

  • analogue 60 watts, 800 lm;
  • analogue 75 Tues 1100 lumens;
  • analogue 100 Tues 1600 lm.

Test with other CREE LED : 60, 75, 100 watts. Test with other CREE LED : 60, 75, 100 watts.

Colour Rendering Index

Color Rendering Index CRI, which determines how well indulge in color when illuminated how a light source.Even with the same color temperature of the luminous flux, color rendering may be different.

 

CREE Color Rendering Index 81 CREE Color Rendering Index 81

CRI Филипса CRI Philips 81

Lamp with Color Rendering Index 93 Lamp with Color Rendering Index 93

The results of the comparison

Both bulbs just showed excellent results in brightness. They use different proprietary diodes capable to maintain their performance when the temperature rises to 135 degrees Celsius. With the power of 18 and 19 watts, they are decently warm, due to the small radiator. If you place a bet on the exemplary quality, they will pay off better than some of the Chinese with the same parameters
