Artificial lighting systems are transitioning from incandescent to compact fluorescent lamp (CFL) and light-emitting diode (LED) bulbs in response to the U.S. Energy Independence and Security Act and the EU Ecodesign Directive, which leads to energy savings and reduced greenhouse gas emissions. Although CFLs and LEDs are more energy-efficient than incandescent bulbs, they require more metal-con...

All artificial lighting devices undergo some color shift over the course of their useful lifetime. Unlike incandescent and halogen lamps, which display a gradual shift along the Plankian locus, energy-efficient lamps degrade Color-Correlated Temperature (CCT), in a non-blackbody manner. This exacerbates a generally poor appearance, and can impede public acceptance, especially among residential ...

The use of solar modules to meet the needs everyday life is something interesting use. Harmonics a phenomenon power quality deviation that can distort voltage and current waveforms. In this experiment, simple inverter with 1000 W capability will be used, then loaded water pumps other household appliances. method used measure factor harmonics generated by using measuring device. process assessed...


 The circulation of Energy Saving Lamps or Self-Based in Indonesia, which promises the shape lamps, variations lamp power, life, comparison offered brightness, low power absorption with brighter light, has caused many people to switch from using tube lamps and incandescent other types lamps. this lamp. Indonesian Government regulation that requires LHE manufacturers include National Stand...

the experiment was carried out to study the impact of chilling and night break on the flowering of ornamental plants in their off-season period. larsenianthus careyanus (benth.) w.j. kress & mood is a wild potential ornamental ginger naturally growing in the evergreen forest of north eastern states of india was selected for the current study. the rhizomes were collected and stored at 15oc f...
