    Une Led haute luminosité s'alimente en courant constant et non en tension constante or ici on ne connait pas l'intensité et je sais par expérience qu'il vaut mieux éviter de se fier à la puissance pour en déduire l’ampérage (puissance arrondie, max ou exagérée). Sous 12V précis je mesure de 450mA (à froid) à 500mA, elle ne chauffe quasiment pas et est déjà bien éblouissante. À partir de 900mA un radiateur devient obligatoire. Je l'ai testée jusqu'à 950mA (env. 12.5V) ce qui correspond à 12W et je trouve son échauffement très raisonnable en comparaison de sa luminosité.

    I have received my COB LED's today and have had a little play and they are very bright indeed. I tried single twin and triple COBS together, the amount of light is fantastic. I have purchased these to make a site work light and think they are going to do the job great.

    The quality is excellent. Light is good and they can be connected directly to 12V led drivers without current regulator. The working temperature is good and they don't need heat sink. The lateral holes allow easy fixing.
