It is an explanatory article there is no reason to delete it.
On the other hand, as there are so many types of led on the market, I do not quite understand what type of led the article compares to SMDs when it says "traditional led" ...
Disadvantages of an SMD led bulb:
* The SMD led heats much more than a traditional led when we try to get the maximum it can offer us which is not without consequence since the life of a led lies in its possibilities to keep its lighting power and heat is one of the 2 factors that can influence this lifespan with the overvoltage.
* For the most powerful SMD LEDs, their dimensions limit the number of LEDs according to the space that contains them, so it is not possible to put as many as conventional LEDs.
* More complicated to weld, they require very specific welding equipment since very often we use the technique of fusion soldering (to simplify the soldering is already on the underside of the led and the heat causes the led to solder on the printed circuit ) which makes any subsequent intervention quite difficult if you wish to replace a defective LED.
* According to our tests, the Lumens / watts ratio is the lighting power divided by the power consumed is lower than traditional LEDs.
I do not agree at all with the 2nd point: on 50 mm in diameter there are rarely more than 60 classic LEDs and on the last point: the lm / w output is catastrophic with traditional LEDs ...
In terms of benefits:
Advantages of a SMD led bulb:
* It is a surface component, it reduces costs but above all the finesse in thickness of the products designed.
* The larger SMD LEDs offer more power per LED per unit, for example we can reach 10 ~ 12 lumens per LED when the best 5mm LEDs we use are around 4 ~ 6 lumens per LED, however these LEDs use 3 light chips instead of just one so it's difficult to compare them.
* The angle of diffusion, it is generally quite wide and very often offers an angle of 140 ~ 150 ° nevertheless certain traditional LEDs offer the same performances.
We actually have 4.6 Lm / Led which shows that the LEDs are not too boosted, favorable to their lifespan but I have never had a traditional LED bulb that had such a lighting angle.
In terms of heating, I have not yet measured anything yet, but to the touch, the 3W GU10 SMD model heats less than a GU10 3W model in Luxeon ... Yet the Luxeon model has cooling fins and not the SMD model.
