If the LED will be enclosed check that the bulb is designed for an enclosed fixture.
What light bulb is closest to natural light?
Halogen bulbs are a type of incandescent that gives a close approximation of natural daylight, known as “white light.” Colors appear sharper under halogen light and the bulbs can be dimmed. They’re a little more energy efficient than incandescent bulbs, but they’re more expensive and burn at a higher temperature.
What are the 3 types of light bulbs?

Why are LED lights better than incandescent bulbs?
LEDs use much less energy than incandescent bulbs because diode light is much more efficient, power-wise, than filament light. LED bulbs use more than 75% less energy than incandescent lighting. … Another advantage of LEDs is the “hassle factor.” LEDs last a lot longer than a regular bulb.
Are LED lights bad for your eyes?

What happens if you put a 100 watt bulb in a 60-watt socket?
Putting a 100-watt bulb in a 60-watt fixture could cause intense heat, melting the light socket and the insulation on the fixture’s wires. Any time you have that kind of damage on wires, you’re at a big risk for arc faults, where an electrical current falls off its intended path— a leading cause of home fires.
