COBs are the near future, they just need to catch up a bit. But whatever, here's the future today. Fuckin hell, you just can't make any damn statements anymore without some wiseass inventing the next big thing while you're asleep. LOL. Courtesy of LED Inside

Genesis Photonics’ (GPI) 3D Chip On Board (COB) successfully integrates blue
LED components with a variety of remote phosphors. Compared to the average COB product, 3D COB has better lighting quality and has the advantages of greatly reducing lighting system costs, and expanding the market for new lighting applications. Moreover, using a combination of high powered blue LED components with patented remote phosphor offers lighting fixture manufacturers additional patent protection.
GPI’s 3D COB integrated solution can be used with dimensional lighting or plane lighting remote phosphor solutions. Compared to single or group LED packages, where phosphor is placed very close to the die and receives near range concentrated light source stimulation, the remote phosphor used in 3D COB are is located further away from the die and excited by long range light source. The advantages provided by such an arrangement include excellent lumen maintenance, small differences in hot-cold factor, and slight color shifts. In addition, by applying remote phosphors in GPI’s high luminous efficacy Match LED, it is also able to get improved color uniformity and diverse color temperature options. For luminarie manufacturers, these technological advantages open up a lot of opportunities for luminaire manufacturers to create more flexible light fixture designs.

| Hot-cold Factor | Slightly | Normal |
| Design Options | Can be matched with many remote phosphor stimulation solutions. | Phosphor painted on the package interior |
| Luminaire design/ components used | Flexible with low inventory risks. | Standard specifications that are prone to inventory risks with changes in client demand. |
Standard specifications can cause inventory risks when client demand changes. GPI’s 3D COB’s core light source employs the patented blue light Match LED component, a technology developed by the company. The component is constructed on the foundation of AT chips, and includes the following features: wire-bond free, compact arrangement, low thermal resistance, and high light efficiency. From the AT die, MATCH LED component, to the 3D COB light source solution, GPI has been cooperating with top international phosphor brands, to provide sophisticated light efficiency levels and patent protection. This also helped improve luminaries’ clients’ opportunities of entering the global market. Currently, GPI’s 3D COB is being introduced to lighting manufacturers in the U.S., Japan, Europe and China. The company is currently cooperating with a top global distributor to promote and sell 3D COBs.

. COBs aren't there yet in radiometric power IMO, so trying to keep your light on the plant is paramount to me if you want to grow with a COB right now. As Chroni, (What up bro?) has pointed out LED light bulbs are using COBs now and while 120 degrees is great for lighting a room it isn't the best for growing and flowering cannabis when your light source isn't all that. Yet. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- You know what's funny Bumping? I was just reading something and it stated that according to Haitz's Law, sometime in 2015 RGB based white diodes will pass phosphor based whites in performance, (Shhh. Don't tell SDS, He got all bent out of shape last time when I stated that RGBs are better than his fuckin precious phosphors. LOL) So basically, you'll probably see the death of remote phosphors around 2016 and questions about what pump to use will probably be moot, but who knows. From what I know all COBs are remote phosphors but the phosphor is in the body of the device, not on the chip so you want the highest efficacy for your chips, with the least amount of cooling necessary. Still you do need a certain level of performance to grow with so ideally you want the smallest chips that produce the most light. Of course this may be cost prohibitive to most, so compromises need to be made. But then again this is just all talking till companies start putting out MCOBs and maybe phosphors will still have a place in our future. Peace.
Thanks for the clarification.
I found an ant and a little spider (one of the little jumpers you find on the side of your house) in my veg tent today! They must have come through the 10" exhaust duct from my window AC that's hooked up to the attic.
