How bright can LEDs be?

Re: How bright can LEDs be?

A few years ago we got a new top for our 8' EZ-Up tent, and it actually has a kind of space-blanket material on the inner side. Makes it nice and dark under that tent.

Scott,
Which top was this?

Look for "UV coating" in the description.

Of course it can be done, but the expensive consoles will sell with or without that feature, and the budget consoles can't even consider it.
a quick tally of the X32 brings me to 692 LEDs, not including the actual main screen backlight. to do what you're asking means upgrading every one of those, adding potentially hundreds of transistors if they need to be PWM'd, potentially upgrading the power supply, potentially upgrading or changing the cooling.
It's one of those design decisions where I wouldn't be surprised if they already had the discussion of 'how dim can we make the LEDs before too many people complain'

At that number of LEDs, you can guarantee that they are already being driven in a matrix, and thus PWM is just a matter of software (or FPGA gate-ware).
But it is a matter of individual LED cost. At that number, going from a 3 cent LED to a 10 cent LED that can cope with the greater instantaneous current (brighter) blows the parts cost in a budget mixer. Going over-current on a cheap LED is a sure way to destroy them.
