Arcadia Reptile GoldenSun coloured reptile heating lamps, have been specifically designed to produce high levels of bioavailable energy at a slightly lower colour temperature than has been possible before in standard incandescent lamps. As lighting experts, Arcadia have been able to create a whole lamp range that emits a colour of light at CCT-2300k, this creates a highly naturalistic sun-like golden hue which is deeply warming for captive reptiles and maintains a high CRI. GoldenSun coloured lamps maintain the production of bioavailable heat, being optimized for deep tissue warming, whilst creating a visually warming golden colour.
