(1) OSRAM light bulb: halogen eco classic A 64542 A ECO 28 Watt 2700 K, E27 threads, 345 lumen light output
(2) LUMIXON LED lamp, 88 LEDs, 4.4 Watts, 320 lumens brightness, 3300 K E27 thread, E27-1227
Inventory: Pentax K20D camera. Lens: Tamron AF 18-200mm 1: 3.5-6.3 (IF) macro, tripod, test box with two versions.
First pictures were made in a Manuel darkened module so that you can better judge the rays of light and light intensity.
It would the aperture to F4, exposure 1/180, set ISO 100 and focal length 28mm.
The lamps test is there is not a 1 to 1 luminous intensity getraue. In the original, the lamps light much brighter!
According to manufacturer information, should the OSRAM halogen lamp be strong 345 lumen and a 35 watt bulb replace consumption of 28 Watt.
The LUMIXON LED lamp, however, 320 lumens strongly to a 45-55 watt bulb replace. Talk at less lumens, the LED lamp to replace stronger bulb.
LED lamps test against light bulb
LUMIXON LED lamp 88 LEDs
On the test image, we can see that more than an incandescent lamp a led lamp actually. Although the LED lamp is a little longer and thus something sits deeper about 3cm, but along the light, it can be seen that the LED lamp makes a steady and strong light.
In particular you can see this one generates not even light on the light bulb. When the LED lamp is the reproduction of the light evenly and cleanly. The LED lamp has 360 ° light angle and has a very wide light radiant left and right.
When the light bulb the light is before uneven, rough breaks off and is brighter than on the other in some places. The minus axis is the light weaker than for the plus. Including the object receives no light.
On the next screens we tried to allow as much as possible represent the light ratio high-fidelity. The following settings would be taken: aperture of F4, exposure 1/45, ISO 100, focal length 33mm.
LUMIXON & OSRAM light comparison

Here, too, you can see that the LED lamp is much brighter and the light has a clean and uniform distribution.
The light bulb has the same problem. Left minus axis is weaker and the related object is illuminated very weak among them.
With the tests, you can see that the LED lamps not only to almost 90% consume less energy, but also much brighter light bulbs are halogen than that. With LED, it has a clean and uniform distribution of light lamps.
