For years African violets have been successfully grown under florescent tube lighting. For the last 5 years I have been growing some of my plants under LED (Light Emitting Diode) lighting. The bulbs (lamps) have been historically very expensive costing as much as $100 per bulb. Recently I saw a demo with a LED chip lamp. What was so striking was the significant electricity savings possible even when you add in the total cost of the new bulbs (lamps) and fixtures. I worked up a spread sheet so the variables can be accounted for and anyone currently using a florescent set-up can do a simple comparison on the linked spreadsheet by just adding what they have and what they want. It will calculate the potential savings, how long before you break-even after you purchased the new equipment and what amount of savings over seven years can be expected. Feel free to download the spreadsheet if you wish or just use it here on site.———–>Electricity Calculator
I have attached some digital images below of what the LED Chip Lamp looks like and a close up of the tiny little chip that essentially converts the current into light at a >85% efficiency rate. This means it only loses less than 15% in heat.
A magnified view of the yellow chip inside the LED lamp. Note the 6 tiny diodes in the center, this is the source of the light that will be emitted when the power is turned on (double click on image to enlarge).
Below is a nice video I found on youtube that gives a brief discussion about the chip tech LED. The actual discussion starts about 18 seconds into the video.
