Solar Crystal (Brilliant Light!!!)

A golden crystal block with what looks like a mini sun within it.

Would create light over a wide area with brightness like that of the sun, and cause things close to it to catch on fire.

Two possible functions for it.
1. That if glass is arranged in a pattern near it, it will result in a effect like a magnifying glass, creating a beam of light that causes things that enter the beam to catch fire and take damage. Though it does no damage to blocks that can't burn.

2. If surrounded on all sides with TNT, which then detonate at the same time, would function like a nuclear bombs implosion, and result in a huge explosion that looked like the sun, the more TNT around it that detonates at the same time, the bigger it's blast.

As an aside, if there is ever a Heaven or such to contrast the Nether, this would really fit with such a dimension of Light.
