Effect of Incandescent, Fluorescent and LED lights at 900 lumens on the concentration of vitamin C content in oranges and their effectiveness on metabolic efficiency

Incandescent generate light by use of filaments and when power is applied, the filament glows generating heat and therefore light. Due to incandescent bulbs hot filament, they produce a continuous spectrum as all wavelengths of lights are present (Fielder 1). On the other hand, led produces lights through a cold process as it is stimulated by electron movement, hence creating photons, therefore, visible light and its wavelength is the only thing emitted by led bulbs (Lighting Division 1). Fluorescent lighting uses electricity to excite mercury gas and in the process emits ultraviolet light (Nave).

Environmental Mangement - Upland Burning in Ireland and the Effects of the Heritage Bill 2016.

The Heritage Bill 2016 will also Acts amend and extend the Wildlife Act 1976 and outline the powers issued to the authorized bodies under the Act. Provisions will also be made in the Bill to amend the Canals Act 1986 (Department of Arts, Heritage and the Gaeltacht, 2016). The Bill comes as a manifestation of the Irish Government?s poor record in listening to the cohorts of people who value our natural heritage. This is evident in the lack of scientific rationale to support these changes (birdwatchireland, 2017).
