The answer to this question is simple: there are no
white LED chips, they simply do not exist.
Philips’ MASTER LED GLS lamps have an
unusual yellow appearance yet still achieve a colour temperature of 2700k. As
soon as the lamp is turned on its yellow appearance disappears. This new
innovative lamp is available in 13, 17 and 20w BC and ES caps, is dimmable and
has 25,000 hours life.
The lamps colour is enabled by its remote phosphor
design. To emit white light, a blue led chip is used and a yellow phosphor is
applied over it. The combination of these two colours invokes the phenomenon
known as metamerism. Metamerism occurs when our eyes and brain perceive two
different but complimentary colours as mixing together to create a third
complementary colour. When the blue
light shines through the yellow phosphor it is down-converted into what our
eyes perceived to be white light.

| Philips MASTER LED's omnidirectional beam capabilities |
The powerful specifically positioned blue LEDs are countered
by the yellow phosphor coating producing a bright white omnidirectional light.
The light emitted from the lamp can be radiated in any direction, even
downwards, allowing it to emulate an incandescent lamp.
