Review (positive): Osram or Sylvania LEDriving white LED bulbs in W5W or 501 wedge socket format. This design is identical in size and shape to filament types, and has a forward projecting single chip behind a subtle diffuser lens.

These replace 5 W filament bulbs although the configuration means they will not suit any ‘sideways’ mounting. Available in 4000 K “warm” (more of a neutral pure white) or 6000 K “cool” (i.e. blue). I wanted sidelight bulbs that would be close in color to high end halogen headlight bulbs but also a neutral white that looks good on its own.
Reviewed characteristics include the bulbs’ design, power, and color.
* Claimed: 4000 K / Measured: 4150 K
* Claimed: 1 W / Measured: 0.6 W (still brighter than a 5 W filament)
* 5 year non-commercial warranty, claimed life 5000 hours.
