The LIFI plasma arc light from Luxim is one of the most exciting, promising new technologies which is taking many different lighting application by storm. Street lights, the military, the aquarium hobby and alternative lighting applications are all very anxious to see how the LIFI will perform once it is released into the wild, outside of the few beta fixtures which have made it to the Monterey Bay Aquarium and the Steinhart. The spectrograph above was a kind email gift we received from Wyatt Patry and used with explicit permission from Luxim to show how the LIFI sheds certain wavelengths of light as the power level is reduced. The reefers in the house will surely rejoice to see that red light disappears first allowing us to have a dusk to dawn dimming cycle which more closely replicates natural sunlight as seen from several fathoms under the sea. The color of the spectrum plot lines was artifically inserted by ourselves to show the shift of the perceived color temperature; please note that at <25% intensity the calculated color temperature (CCT) approaches infinity which basically means that it’s too blue to put any real kelvin numbers to it. Needless to say we can’t wait to see the first production LIFI-equipped Seashine lights from Stray Light Optical at ReefStock in just under two weeks. Huge thanks to the Monterey Bay Aquarium and Luxim corporation for sharing this awesome data image with us. Follow the break for some real values regarding a selection of wavelength peaks.
The following is a short summary of the notable wavelength peaks of the LIFI at the full intensity of approximately 250 watts for the emitter:
- 380 nm – 0.04 watts
- 400 nm – 0.08 watts
- 420 nm – 0.118 watts
- 449 nm – 0.156 watts
- 460 nm – 0.164 watts
- 500 nm – 0.190 watts
- 521 nm – 0.183 watts
- 548 nm – 0.187 watts
- 591 nm – 0.205 watts
- 599 nm – 0.190 watts
- 662 nm – 0.140 watts
- 671 nm – 0.113 watts
- 730 nm – 0.048 watts
- 757 nm – 0.057 watts
