  • I am using 65 watt bulbs in recessed light cans. Would the ZetaLux LED 7 watt bulbs work in this situation.
    Thanks
  • The Zetalux will produce less light than the 65 Watt incandescent bulbs. It might be a good idea to order just one of them, test it, then order more if it's sufficient. The Zetalux is not dimmable, either.
    
    If you need a dimmable downlight, you might look at this bulb: http://eartheasy.com/energy-efficiency/energy-efficient-led-lighting/lumiselect-par-20-dimmable-led-bulb-9-watt-warm-white
    Keep in mind, however, that it produces less light than a 65 watt incandescent as well.

  • how many led lamps do we require of this type in an area of 150 square metres.
  • When estimating how many 7-watt ZetaLux LEDs will illuminate an area of 150 square meters, the simplest measure is to compare with a 60-watt incandescent bulb. If you are already using light bulbs for this area, add up the total combined wattage and let us know. This would make it easier to do a comparison for you.The height of the ceiling (if you are using ceiling hung fixtures) and the nature of lighting requirement (e.g. task lighting, general area lighting) need to be factored in. It would seem that 20 bulbs may be needed, but this is just an estimate.

  • I am looking to replace quartz lights in a 5 lamp track light fixture. I insrtalled a ceiling fan but had no way to run a switch leg to the track light. Hence I cannot run the fan to circulate heat from a wood stove without running the 250W of track lights even when I don't need them on.
    The quartz lighting is already harsh but bright. Is there a "bare lamp" LED lamp I can replace my current lamps with? I can't afford to leavfe them on, but I want to be able to run the fan most of the time in the winter.
  • A comparable wattage output LED track light is the LumiSelect PAR 16 Dimmable LED Bulb - 6 Watt, Warm White bulb which has a standard Edison base.

  • I am looking at replacing the current 3-way light bulbs in a number of old lamps in my home. A number of the lamps have small harps that have prevented me from replacing them with the compact florescent bulbs that I can currently find in retail stores that are too large (bulbs 6-7 inch length or two wide) . What LED Soft White light bulbs do you recommend to replace the following bulb/harp combinations:
    
    50-100-150 Watt with a bulb length under 5 inches
    70-120-240 Watt with a bulb length under 5 1/2 inches
    100-200-300 Watt with bulb length under 6 inches
    
    Also are jumbo base 100-200-300 Watt bulbs available for some antique floor lamps.
    
  • The ZetaLux 7 watt bulb dimensions are 5.46 in (138 mm) Diameter: 2.71 in (68.9 mm). It is 50 - 60 watt incand. equivalent.
    
    The ZetaLux 2 Pro 7 watt bulb dimensions are 4.21 in (107 mm) Diameter: 2.36 in (60 mm). It is 60+ watt incand. equivalent.
    The ZetaLux 2 Pro is smaller than the original ZetaLux, so it fits in the same fixtures as a standard incandescent.
    
    The EvoLux SH LED 13 watt bulb dimensions are 4.44 in (113 mm) Diameter – 2.55 in (65 mm), with 100 watt incan. equivalent.
    
    These LED bulbs are not three-way. They will, however, work in three-way fixtures. They will deliver the same output at any setting in a three-way fixture.
    
    These bulbs are available in cool or warm light.
    
    Jumbo base bulbs are not available in LEDs to our knowledge.

  • Is $35.95 the cost of one bulb? If so how can anyone afford this?
  • Yes, $39.95 is the cost for a single ZetaLux LED light bulb.
    
    It sounds way too high-priced for a light bulb, but it will save money when compared with a typical incandescant light bulb. Your basic electricity costs go down because the LEDs give the equivalent illumination but at a much lower wattage. Also, over the lifetime of the bulb, it also costs less than the incandescants you would use during that time.
    
    Here is a page with several charts which illustrate how LEDs are cost-effective as well as energy-saving:

  • Can LED lights be used outdoors during cold weather? Or outdoors at all? We can't use CFL's outside in coldweather especially, even in protected light fixtures. Are LED any different?
  • Yes. The ZetaLux LED light bulb has been tested and proven outdoors at efficient at extreme temperature on both ends of the spectrum. It has performed adequately in temperatures as low as -50 and as high as 180 degrees.
