Barcelonaled R39 4W And 5W R50 E14 Reflector LED Bulbs

Thanks again to BarcelonaLed for sending me these bulbs to be published on the blog.
These are the first reflector led bulbs that I analyze with what I take to add a new section in theranking of bulbs with this category: bulbs that have E14 or E27 socket, but whose angle concentrated more light than spherical normal bulbs to light up in a more pronounced way.
This model R39 is also the led bulb of smaller size which I analyze so far and it is a new model that mounts leds smd 2835 (model that’s currently on the website of BarcelonaLed corresponds with a similar light bulb but 3W and different characteristics or performance).
Tests
According to Ledbulbbay.com, the LED bulb consumption is between 4.1W and 4.4W, with power factor quite low of only 0.42 surely due to the small size that has and the limited space available to place the driver electronics.
Still does not produce any interference in the radio if plugged it into the same socket, so unless the driver is better insulated and must be of better quality than the of other led bulbs analyzed.
Although I could not remove it, you can get to see points of light from the leds and seems to be riding 7 leds.
In the ranking of bulbs is incandescent 40W E27 above a light bulb giving more light to the front but less at the sides (which in the end and after is what is intended with this type of bulbs focusing more light).
The temperature that reaches the bulb is between 26 ° C and 55 ° C, heats but does not burn after a while turned on although it is so small that only has power 4W.
The holes between the body of the light bulb and Cap you can look inside having aluminum to help the dissipation of heat and away from the leds.
Reflector bulb E14 R50 5W:
This bulb is exactly the same size as a Philips R50 incandescent reflector of 40W and 30º angle of light:
Consumption: 5W (measured 5.2W)
Energy rating: A +
Equivalence: 50W
Lumens: 410
Color: 4000K
Angle: 120 °
Power factor: measured 0.55
CRI: 80
Adjustable: No
Dimensions: 83 x 50 mm
Duration: 25000 hours

And this is the new model of reflector R50 of 5W which also mounts 2835 smd leds and is the same size as the incandescent R50 reflector of 40W Philips I have to compare the performance of this type of light bulbs.
On the BarcelonaLed website there is a model R50 4W but it is not the same since it also has different features and benefits as is the case with the R39.
Tests
The measured consumption is in the 5.2W with a 0.55 power factor and again also produces no interference on the radio if we connect it in the same socket, so the driver seems to be better insulated, or better quality than the one of other analyzed bulbs.
With the lit bulb can be see points of light from the leds, which in this case seems to be that mounted 10 leds.
With respect to, the operating temperature is between 24 ° C and 60 ° C which reaches some point of the bulb, heats but not to burn. And like the other bulb can also be seen through the holes at the edge of the CAP which has aluminum to dissipate the heat inside.
In terms of light that gives, in the ranking of bulbs is above the previous reflector of 4W, giving one 36% higher average light spending only 1W more and closer to the light that gives an incandescent bulb of 60W.
I have done the test onto the floor lamp from the dining room where I have a low consumption of 7W bulb and the bulb comes on instantly and gives the feeling of light at least twice (in the direction where it says lamp).
Even placed in the bathroom mirror light up surplus basin surface (although not lighted part of the roof off):
I also have to say that unlike other led bulbs that have analyzed with socket E14 and sometimes are “damn” enough with some Socket not making good contact (for example the Ledare of Ikea) because the shape of the CAP and the thickness of the body of the bulb won’t let them screwed well, these two bulbs have well entered the first and have not given me any problem.
Conclusion
The shape of these reflective bulbs concentrated more light than normal, what are suitable not only for installing them in hot spots where already had reflector but also in lamps or hoses where we want to illuminate mainly in one direction, achieving approximately the same intensity of light that an incandescent but with a consumption of between 8% and 10%.
They have an angle of light larger than the classic reflector that tend it to have very closed (which I have have an angle of 30 degrees and I’ve seen others only 25°), by which also illuminate more area.
Both lamps seem to fit better than others tested electronics since they do not produce interferences (even if the power factor is quite low).
And although they become hot, not reach temperatures of 80°C which can be found in other led bulbs, on the one hand because they have little power (4W-5W) and also by way of “mushroom” that are making the bulb body have greater surface area in contact with the air which facilitates the dissipation of the heat.
