Philips is releasing a new type of design for the 60-watt incandescent replacement LED bulb. Philips's SlimStyle LED removes the heatsink found on most LED
bulbs. Without heatsink the light should cost
significantly less to manufacture, which translates to lower selling price. Philips hasn't disclosed any retail price yet.
CNET compared the SlimStyle to Cree's A19 60-watt incandescent replacement LED bulb. Both bulbs show similar specification, but in actual there are some differences.
(1) SlimStyle is slightly more natural and less yellowy in tone than the
Cree.
(2) Even though both claims to be omnidirectional, meaning
that they cast light evenly in all directions, distinct dim areas are seen on each side of the SlimStyle's
arc. Cree's A19 shows a much even light distribution.
(3) Cree comes with 10-year warranty and Philips only offers 3 years.
In the end, it will all come down to pricing. If the
absence of heatsink is enough to keep the cost per bulb way below US$10, then SlimStyle stands a good chance to capture the market share.
