LED vs Incandescent Picture Lights

I learned today of a large building with several thousand art works all illuminated by incandescent lights. While the initial cost was relatively low, the cost of ownership has proved very expensive for the labor and material of having to constantly replace burned out bulbs. Not to mention the damage to the artwork from the heat and possibly ultraviolet radiation from the lights.

An organization installing our Ektralamp LED-based lamps today would ultimately have a lower cost of ownership while eliminating heat and UV radiation of other types of lighting.

  1. I was just wondering how to take a 5mm LED light with two little wires coming off the bottom, and hook it up to a light switch using a 9volt rectangular (I forget the name/letter) battery. Would I need more wires? What kind? How could I do this? Thanks..

  2. Sherwood Cox – I certainly like the idea of reindcug my power consumption and would change all of my bulbs as they burn out to LED’s. Unfortunately even the newly marketed warm 3000K and 2700K LED’s have a funny blue green color cast to them and aren’t as warm as they claim. I just tried a couple in my kitchen and took them right out and put some par 20 halogens back in.As an architectural photographer I have a lot of trouble shooting commercial buildings balancing the CFL, LED, florescent and halogens with daylight from the windows and my strobes or hot-lights on photo-shoots. I have to shoot with each light source on one at a time and correct their color separately before blending them together in photoshop. Basically the same way I did it in the film days except with no color temperature meter and not color correction filters, just a gray card. I can’t wait for the technology to get better. It would be nice if engineers could get all of these types of lighting to pout out the same color temps of light so we could choose weather we wanted warm or cool lighting without a color cast.

    • Nice, concise sumarmy. You are quite right, the best and the most frugal are not the same at least, not yet.LED lighting technology has been advancing rapidly. There have especially been major gains in efficiency in the past year. Cost is also coming down.I have seen two LED lighting units in the lab that are hands-down winners over incandescent, halogen and fluorescent in terms of the quality of the light produced, intensity, and the variability (dimming without a red shift). One unit is a reading lamp. The other is an uplighter equivalent to a 480 watt halogen, using a fraction of the electricity. This won’t be available to buy until patents are filed, but what they do for art books, tapestries and paintings has to be seen to be believed.At my blog you will find out why each type of lighting currently doesn’t look quite right. You will also learn what improvements are coming.
