For more light, you simply use a larger area but still get the same benefits. The automotive industry, among others, just couldn't wait to finally lay hands on a LED that can be shaped at will and will no longer emit a clearly visible string of small points. | |

I don't know if this is why you chose it, but at 8:30 he shows a picture he took of the filaments at low current/dim brightness. In this picture you can easily count the 18 individual LEDs hiding under the phosphor, which illustrates the construction nicely. | |
