This is the only FSL Laboratory Certified Replacement Bulb For Your Full Spectrum Lamp. Works with Lamps Designed For 42-Watt Full Spectrum Bulbs.
Don’t be fooled by imitation “Full Spectrum Bulbs” that guarantee a 10,000 Hour Life Span. They test their bulbs by turning them On only once and timing them until they burn out. Our Bulbs go through a FSL Laboratory Certification Process where they are turned On and Off Hundreds of times during testing. By subjecting the bulbs to maximum surge strains we know they will last a minimum of 8,000 hours under the most frequent use.
The FSL Laboratory Certification Guarantees all of our Bulbs project True Full Spectrum Light, not imitation florescent light that claims to be “Full Spectrum”. If you enjoy the Earth's Natural Sunlight then you will Love our Full Spectrum Light Bulbs.
