I think people are misunderstanding the term COB- it stands for Chip On Board- a type of LED. It doesn't refer to the style of lamp- specifically looking like a corn cob.

In COB lighting, single LED chips are placed directly on a circuit board (or substrate) which has thermal properties to disperse heat. Heat dissipation is a very important aspect of LED lighting because it can have a major impact on the life expectancy of the luminaire. Traditional LED chips are not placed directly on the substrate and therefore there is greater thermal resistance.
Unfortunately Chris, your correction will fall on mostly deaf ears as you'll see this misunderstanding of what a COB LED bulb is repeated endlessly on these forums. :S I've been using 16 of these non-COB LED bulbs, each consisting of 24 5050SMD chips, for a year now with no failures at all, no RFI disruption of the radio, bright with a rated colour temperature of 3200K, in fact no complaints at all from me.
Sourced at a reasonable price from this offshore vendor ... and while certainly not the latest & greatest in terms of LED construction have worked just fine for me. :B
