I have been having a big problem with my cheap light bulbs. I replaced three halogen lamps that had independent drivers (transformers) rated upto 60W with 3 Osram 12v MR16 LED dowlighters rated 1.2W each. Needless to say, all these LEDs blew up within the first two weeks. I then purchased an LED driver branded Osram and rated 60w. According to the shop attendant & the user manual, i only need one driver for all three lights. I proceeded to remove all the halogen transformers and replaced them with the new LED drivers. When i connect all three lights to one transformer, they light up but go off after a couple of seconds and sometimes flickering is noticed. When i connect just one LED Fluorescent Replacement, it stays on for hours.
What i need to know is must i connect each LED to its independent driver or is something wrong with my connections?
P.S, i have oconfirmed and reconfirmed that there is no short circuit in my wiring. Please assist You might be using a regular 12 volt dimmer which is modulated width pulses and not made for LEDs. That would cause the flicker. A transformer as a 12 volt source would also be bad for LEDs. They need steady DC, not AC or DC with a ripple.
Places like led strip lighting have a selection of the right stuff.
Have you ever made underwater fish pond lights yourself, HOW ?
I refuse to spend 80 dollars or more on little 12 volt LED lamps or other types. What about LED lamps in water-tight containers, SELF made? Has anyone here done it, and what problems did you encounter? The solutions?
Thanks. My goldfish pond is 3 feet deep in the middle, and maybe 6′ x 8′ rectangle. 33 fish. Some babies every Spring.
Something you could look at is LED Fluorescent Replacement. It is a string of LED’s inside of rubber tubing so the bulbs and wires are sealed from the elements and your connections can be on the surface. You can get them in different lengths and colors. I bought a bunch from Home Depot after Christmas for $15 each for 18 foot long strings.
