These 100% blue spectrum lamps are an excellent source of longwave ultraviolet light required for growth in marine invertebrates. The lamps' spectral energy peaks at 420 nm, simulating the blue chlorophyll absorption peak used in photosynthesis by zooxanthellae.
The lamps have a color temperature of 8,000 Kelvin, are T12 bi-pin and feature a 180 internal reflector to maximize light output.
Available in standard wattages and very high output (VHO). We recommend that Actinic 03 lamps be used in combination with Actinic 50/50 lamps.
Note: Lamps are also known as bulbs.
