23W Tuna Blue LED Bulb Coral Reef Optimized Spectrum 11-Band PAR38

The 23W Tuna Blue Reef Bulb is designed for reef keeping. Eleven different types of LED chip are combined to produce a broadband blue spectrum that more closely mimics the natural ocean environment. The tuna blue light is bright and beautiful with plenty of actinic light to make corals pop. By spreading the light out across a wide range of wavelengths, the bulb produces bright light that grows healthy corals without overwhelming the zooxanthellae living in their tissues. This reduces the risk of bleaching. The broad spectrum light is designed to accentuate florescence and improve contrast. The light is designed primarily for the health of corals, but it also provides a beautiful and colorful viewing environment. The Tuna Blue Reef Bulb is designed and assembled in the USA using efficient chips and quality components. 15 high power LED chips use a true 23W of power. An integrated ball-bearing cooling fan quietly keeps the temperature down allowing the power to be cranked up to a level that would not otherwise be possible with a bulb this size. This product is backed by a 3-year manufacturer's warranty.
