continuous source LED photographic and video lighting

introduction

  • LED lights have largely replaced flourescent and tungsten continuous light sources as they run cool, without flicker, are generally balanced for daylight, are dimmable, last longer, and are much more portable and require lower power consumption and thus smaller, lighter power sources
  • avoid cheap LED lights which are not designed for photography as they generally do not have good colour quality, although for monochrome work or where colour is not critical, they may be very handy and affordable.

how bright are they?

  • these lights are generally rated in output levels in lumens where 1 lumen = light flux from 1 candle
  • the Westcott Ice Light 2 is rated at 1750 lumen at full output, and at around 1m from the subject, this gives exposures of around 1/125th sec, f/2.8 at ISO 400 (light value of around 3) which is about 1-2 stops brighter than average household lighting levels, but certainly would not be useful in sunlight or even cloudy days, and really is best used indoors or after sunset outdoors. It could be useful for macro work in the shade when held 6“ from subject.

  • comes with 2 clips to allow gels to be used
  • 1,740 lumens at 15W maximum output level allows f/2.8, 1/100th sec, ISO 400 when held about 1m from subject and battery lasts ~ 1hr at this output
  • LEDs are daylight-balanced at 5500K with 73deg beam angle and Color Rendering Index (CRI) of 96 (max. score is 100) for excellent skin tones, and rated for 50,000 hours, or 17+ years if used 8 hours every day
