How to convert old bulb to LED bulb

There is a great quantity of evidence pointing to the energy savings of LED bulbs but in contrast they do have a particularly high price tag. Another factor in their benefit is long life and high reliability so how do you evaluate whether they are worth purchasing? If you want to get a correct perspective on the commercials you need to work out the total cost of ownership and use of LED Bulbs and compare this to established incandescent light bulbs.

The advent of 12-volt LEDs with bases designed to fit most 12-volt bulb-holders makes replacing 12-volt bulbs a realistic task for people with little or no electronic knowledge. Here, let’s find how to convert a 12V Bulb to a LED Bulb.

1 Switch on the power supply to locate the bulb and the wires supplying electricity to the bulb holder. Use a digital millimeter to establish which wire is positive and which is negative. Connect the positive and negative probes across the bulb holder. If the millimeter shows a positive reading, the positive probe is on the positive wire. A negative reading means the positive probe is attached to the negative wire. Mark or label the positive wire. Now switch off the power.

2 Remove the bulb and place it somewhere safe. Check the polarity markings on the 12-volt LED. Insert the LED into the bulb-holder so the positive side of the LED connects with the positive side of the bulb holder. Push the LED firmly into the holder but do not use excessive force.

3 Switch on the bulb. If you connected the LED correctly it will illuminate. If the LED does not illuminate, switch off the power, remove the LED, turn it through 180 degrees and reconnect it with the polarity reversed. Switch on the power and check again. If the LED still fails, try a different LED or put the bulb back in the holder to make sure the power is still working.  anty881209wong 140225

How to use LED Grow Light

Are you still annoyed that your lovely plants won't grow well in the cold winter or cloudy weather when they need natural lights to complete photosynthesis in your inside garden. In this science society, you do not need to this problem anymore. With the advanced LED bulb technology, now the LED grow light can be helpful for garden management. If you are new at use the LED grow light, the following words can help you know more about the use of LED grow light.

1 Determine the optimal lighting requirements for your particular plant or plants to thrive if they were living outdoors. Figure out the intensity of light and for how many hours a day it is needed. Often this information is on the plant tag or little plastic pick stuck in the soil of your plant. Online garden resources can help you make the determination if your plant is unmarked. This is what you need to mimic indoors with LEDs. If your plants grow outdoors in shade they need less light indoors.

2 Provide a mix of red spectrum and blue spectrum LEDs. Plant photosynthesis is most responsive to these two spectrums. According to research conducted by NASA, mixing at least 80 percent red LEDs and roughly 20 percent blue LEDs is a successful ratio for growing plants indoors. You can easily switch out a few of the blue LEDs for white without harming the plant growth. This will allow you to see what's happening with your plants much more readily because white LEDs have a spectrum of green, yellow and orange, which is more easily visible to the human eye.

3 Adjust your LEDs to hang above your plant tops by anywhere from 5 inches to 20 inches, according to the plant's size and light intensity requirements. Your goal is to have the plant greens showered in light to their edges but not have the light spill or be wasted on surrounding areas where there are no plants. Height adjustment of lighting helps achieve this economy as plants grow, changing in both shape and size. anty881209wong 140102
