• 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.
• many are now controllable by proprietary WiFi solutions and some can be controlled via the more universal DMX controller systems

• 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.

• some are AC only which limits use
• some have DC inputs
• some have a proprietary built-in lithium ion battery
• some have a proprietary swappable lithium ion battery
• some have a V-mount battery plate which allows industry standard batteries to be used
• some have an Anton-Bauer battery plate

• see http://www.theicelight.com/ice-light-2/
• invented by Australian pro photographer Jerry Ghionis and manufactured and marketed by Westcott
• NB. version I had some quality issues and fixed battery, and vII is 50% brighter and CRI is better
• uses removable lithium battery pack as well as AC power supply via the DC adapter (optional car adapter)
• USB is only for firmware upgrades NOT power supply
• 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
