I do not use LED lamps in my home. White light is not a single wavelength; it is produced by a combination of different wavelengths across the visible spectrum, including red, green and blue.. Exposure to blue light may have long-term effects on the brain and circadian system. Bright light, especially blue-enriched light, can stimulate the brain’s circadian system and influence the hypothalamic–pituitary–adrenal (HPA) axis, which regulates cortisol. Intrinsically photosensitive retinal ganglion cells (ipRGCs) detect this light and send signals to the suprachiasmatic nucleus (SCN), the body’s biological clock. Some research has also suggested that blue light may influence behaviour.

Research by Professor Glen Jeffery at University College London suggests that mitochondria, the powerhouses of our cells, may benefit from red and near-infrared wavelengths. His research indicates that exposure to these wavelengths can influence mitochondrial respiration and cellular energy production. This suggests that the lack of a natural light spectrum may be more than just a matter of eye strain; it may also have broader biological effects. Studies have found that exposure to specific red and near-infrared wavelengths can influence mitochondrial activity, glucose metabolism and oxygen consumption.  Choose your home lighting wisely. The right light matters.

SOCAR

SOCAR will be shutting down its car-sharing service in Malaysia on 31 August 2026. It was a good service—convenient, affordable and reliable.

No more SOCAR. Use TREVO.

Lee Thiam Wah, the billionaire behind 99 Speedmart, is also associated with Burger King, while his sister, Lee Lay Liang, owns Nature Century Development. These examples illustrate how family and related-party ownership can extend across seemingly unrelated industries, including retail, food and beverage, and property development. The same pattern can be seen in other Malaysian business groups. Jakel, for instance, is widely known for its textile, but the group has also expanded into property development through Jakel Development. Similarly, Naza World is not simply an automotive business. It is part of the diversified, family-owned Naza Group, which has substantial interests in property development through Naza TTDI.

Beyond these family-owned conglomerates, the Klang Valley is also home to some of Malaysia's largest and most established property developers, including Mah Sing, MK Land, S P Setia, Sime Darby Property, Sunway Property, IOI Properties, Gamuda Land, EcoWorld and IJM Land. When you look at the broader picture, it becomes easier to understand why the Klang Valley continues to expand and why property development appears almost continuous. The region's urban growth is not driven by property developers alone. It is also shaped by the diversification strategies of Malaysian business families and conglomerates, many of which have accumulated substantial capital, landholdings and long-term interests in property development.
