    Why are my LEDs so dim?

    I have 5 x 5W LEDs connected to a 12V transformer powering the lights in my kitchen. The transformer is described as 20 - 60W so at 25W I'm above the minimum load requirement. The lamps are described as 10 - 30V 5W LEDs so with the transformer output at a stated 11.6V I'm within the tolerances...

    Flickering leds

    Hi I've checked other posts but not quite the same, if the kitchen four light spot bar hasn't been on for a few hours it flickers for two minutes then settles down, whereas if I turn the other kitchen light on they stop flickering straight away. At the same time the Lounge light will flicker...

    MR16 LEDs - less video shimmer from dimmable lamps?

    Hi - I have a room lit by two undimmed strings of six x 4.5W MR16 no-brand non dim lamps. This system originally had 50W halogen MR16s and 2 x 300W torroidal transformers. Visually this was OK, but video flicker on a webcam was terrible with the LEDs (none in daylight or with a halogen lamp)...

    Max circuit length for LEDs powered by constant current driver.

    Hi all. Constant current LED lighting is a new concept to me. Not that difficult to get the head around, but I cannot find an answer to the following question: How do I determine the maximum length of a ELV LED lighting circuit powered by a constant current driver? For a constant voltage ELV...

    Power adapter for LEDs caught fire?!

    So I’ve bought a cheap set of LEDs on Amazon and the power adapter broke after three uses. After fiddling with the adapter (bending the wires) it would begin to work again for a couple of seconds before cutting off again. Eventually, at the right position the LEDs turned back on and it seemed...

    Why are my leds flickering?

    I bought new led fixtures to install (6) on a circuit with nothing else on it but a few more leds. I’ve got them on a Lutron dimmer switch. They flicker pretty regularly. I’ve tried swapping all the bulbs out, and also changed the dimmer switch. It doesn’t matter what brightness I have them at...

    TP24 vs Sylvania LEDs - won’t fit

    Hi, My house came with a couple of dozen TP24 downlights fitted, they are GU10 with the long stems (74mm) I’ve found them very expensive to replace (about£4.50 each) I have bought some Sylvania equivalents from Amazon, and whilst the stem pins look identical they will not turn into the TP24...
