The LED itself needs a heatsink as well. Like power transistors and CPUs, power LEDs produce loads of waste heat (less than incandecent or CFL but still a signifcant amount). Also LED life shortens significantly when heated above 50C or thereabouts, so the heatsinks need to be relatively large to dissipate enough heat at a small temperature difference.

"What," said Trillian in a small quiet voice, "does sundive mean?"

"It means," said Marvin, "that the ship is going to dive into the sun. Sun... Dive. It's very simple to understand. What do you expect if you steal Hotblack Desiato's stunt ship?"

"How do you know..." said Zaphod in a voice that would make a Vegan snow lizard feel chilly, "that this is Hotblack Desiato's stuntship?"

"Simple," said Marvin, "I parked it for him."

"The why... didn't... you... tell us!"

"You said you wanted excitement and adventure and really wild things."

I second prints for the still images, but printing photos is my job so I may be biased. Still, I regularly handle prints from over 80 years ago and the majority is pretty well preserved. Color prints from the '70s tend to fade badly and slide film (even precious Kodachrome) is even worse.
I think nobody in the world knows how long modern prints will last in real world conditions, despite the extensive lab testing that has been done.
