Sapphire Eduion | The Natural Sapphire Company
Here at The Natural Sapphire Company, we use standard full spectrum lighting Kelvin Temperature bulbs. This is similar to the lights that are used in most commercial office buildings (They are standard 4 foot florescent bulbs, but do not have the yellow tint that is common in older 4 foot florescent bulbs).
