In addition to dizziness, migraines, eyestrain and fatigue, it has also been shown that seizures can be triggered by the flicker of traditional fluorescent lighting i
Understanding Power Factor of LED Downlight And How It Effects Your Electrical Systems ?
Power factor is the relationship (phase) of current and voltage in AC electrical distribution systems. Under ideal conditions current and voltage are [in phase" and the power factor is [100%." If inductive loads (motors) are present, power factor less than 100% (typically 80 to 90%) can occur. In AC circuits, the power factor is the ratio of the real power that is used to do work and the apparent power that is supplied to the circuit. The power fact

This means that insulation cannot be cleared away from LED downlights and drivers in spaces such as loft and top storey. The normal LED downlights and drivers can not survive in the insulation due to temperatures generated by the driver itself, which results in overheating.
What's the different between SMD led downlights and COB ?
Have you ever wondered about the actual light source of an LED downlight? The 2 most popular types of LED downlight are SMD (Surface Mount Diode) and COB (Chip on Board) downlight. Both produce high quality light, have a high life expectancy and are extremely efficient. WHAT IS SMD (SURFACE MOUNT DIODE)? SMDs are more efficient than COBs because the light source produces higher lumens per watt, which means they produce more light with lower wattage. They produce a wider beam of light that extends over a larger area
