Threeline GU10 LED Bulb

Here I present another “bulls-eye” led bulb GU10 led COB and who claims to be equivalent to a 50W halogen bulb.
The features are similar to other COB GU10 bulbs already discussed in this blog, but in this case they climb the lumens up to 580 (or 600 for cold light) and the duration up to 50000 hours.
This price of this GU10 led bulb is €15.87, above the average of €13 (bought in a shop of electrical components), but it can be found on the Internet by €13.60 in LEDBULBBAY.
The light angle is 60 °, and mounts a lens similar to the COB Optomax or Barcelonaled with external driver. According to the manufacturer, it is “a lens in PMMA for high quality-optimized to provide a defined and homogeneous distribution of the beam of light entering within the group according to the standard risk-free 62471”
This is the V2.0 of this model of light bulb, according to manufacturer it dissipates less power to win in temperature and reliability and also has an improved and more stable internal power supply.
Bulb size is small and the appearance of the bulb seems to be finish grey anodised (cover of fire-retardant thermoplastic with internal aluminium body)
The led chip Cob mounting is Luminus and in theory gives a luminous efficiency of 76 lumens/W
Highlight, in the container where does is made (suppose it Made in China all), and also indicates the number of power cycles.
Tests
With respect to the light which gives, as it has an angle of 60 degrees instead of 100 degrees as the other COB of Rled, gives twice the light at the front and half in the 45 ° angle, so globally could be giving the same amount of light.
You can see in the ranking of lights that is what more alumbra within cob 8W bulbs being above the Rled and below 12W Microluz.Y Optomax effectively giving more light than a halogen bulb GU10 50W.
And as regards the temperature reaches, after half an hour on some points of the bulb are at 67°C,so that not can not touch heated even GU10 connector terminals.
Sure the connector terminals are at this high temperature indicates that the part of the driver of the heatsink is not isolated and therefore Electronics is subjected to the same high temperatures which probably shortened his life.
I think that the 50000 hours are too optimistic as usual, but we’ll see how much they hold, because these bulbs are mounted on an industrial team that is going to be quite a few hours a day on and already say me if one stops “prematurely”.
In general, except for the issue of temperature which in my opinion is too high, is another light bulbs led 8W we can keep in mind to replace a 50W GU10 halogen COB.
