LED bulb replacement project



I picked up a large quantity of LED replacement bulbs, to cut down on electric use, and heat, on several lamps in the house. The left side above shows what the incandescent bulbs looked like before being replaced with LED bulbs on the right.

The first row has a chandelier with a couple burned out bulbs, so comparing the amount of light between the two is not quite equal. The LED light is nearly the same as before, and the main way to tell which picture is which, besides the former shot missing some brightness, is the triangular flare near the center. This was caused by the specific pattern the LEDs are shaped in on each bulb -- a bit of a pyramid within the pointed shape.

The second row shows the kitchen lamp, where one of the 5 incandescent bulbs was dead before the replacement. With the dark tint of each glass enclosure, this set seems a bit dimmer than before, but is still acceptable.

The third row is a two bulb fixture. The center cylinder with the power cable, that is threaded for the glass stopper is almost too small for the LED bulbs, which only fit after slightly bending the socket. The incandescent bulbs that were replaced had a smaller diameter than the new bulbs. On the left is a flare from the Edison type filament, and on the right are two flares from the sets of parallel LEDs in each bulb. Because the glass enclosure is open to dust collection, the right picture appears much cleaner and clearer because I polished it.

The fourth row is of the hall light that had 4 sockets, only one of which was lit by incandescent before the LEDs were put up. Unfortunately the old bulbs were small spheres, while the new ones are larger ovals that don't quite fit in the enclosure. I needed to let it hang there without being completely screwed in as it should be. Next time I'll measure the old bulbs.
