thought i would start a thread to give info on c.o.b panels and what C.O.B actually means.
here's a simple article explaining what they are all about.
http://www.prophotonix.com/resources/Technical-Overviews/about-chip-on-board.aspx
"COB LED means chip on board LED, it’s one of bare chip technologies, which interconnect bare chip to substrate by conductive or non-conductive adhesive, and then wire bonding to achieve its electrical connection. COB package is attach number of chips directly to the substrate, then packaged together by silica gel, epoxy resin or other materials, the yellow part is phosphor."
where as surface mounted LED's or "SMD LED" is an abbreviation for Surface-Mount-Device Light-Emitting Diode. An SMD LED Module is a type of LED module that uses Surface-mount technology (SMT) to mount LED chips on printed circuit boards (PCB).
also now there are new technologies know as "modular designs" which are basically a number of diode clusters placed into a unit that are easily replaceable should anything go wrong during a grow.
basically non modular panels are the most likely to have a fault that will hinder your grow. if one of the LED's on this type of panel goes out it will more than likely cause a group around it to go out as well. if this happens you will have the option to either finish your grow with partial wattage or send the light back to have it repaired but that definitely wont be good for your plants. and also surface mounted LED's can face this same problem but most likely only one chip will go out rather than a bunch around it. the types of LED grow lights people should be looking to buy are modular designs that have parts that are easily replaceable as then down the line when something goes wrong you wont be running into big headaches. then you can think of your light as a long term investment that can be upgraded in the future rather than something that gets worn out once and is no longer of good use.
an example of a C.O.B panel would be the mars sun series from mars hydro:

an example of a surface mounted LED's is hydro grows SOL models (although they incorporate a modular design as well) :

and an example of modular design would be the GSX series from Grow Standard LED:

any further relevant info anyone wants to contrbute you are more than welcome!
