The CeeLite 7500 and 11000 Kelvin panels are the first flat flexible
lightbulb to contain Light-Emitting Capacitor technology. Flatlineinverters maintain 99% uniform backlighting and make it possible
to offer motion and/or photo sensors with external sensing jacks,
while providing dimming, fading and flashing standard features.

Skyport is a light collecting panel that sits on your rooftopto transmit light into your home. It uses a fibre-optic wire
to send the light to specially designed 'lamps'.
The light can be transported up to 15 meters. With a 7meter cable, the light intensity can reach 4000 lux, and
with two Skyports mounted on an angle will bring in bothmorning and afternoon sun
