I had some Screwfix LED failures. The catalogue advertising blurb claimed if I recall, 30,000 hours, but they failed within six months. Manager refused to replace them as they only replace duff items withing 30 days. I complained to HQ and pointed out the consumer rights legislation. These lamps were not as described E.G 30,000 hours and were not fit for purpose . Anyhow, they replaced the lamps, eventually. LEDs dont like heat, so its a good idea to be selective about the fitting they go in to. A sealed bathroom globe might not be an ideal environment for LEDs!

As for inrush current destroying the electronics, I like to shove a thermister in series. It just takes out the hard knock on switch on.

Hi,

I found Lotoxane (Arrow Chemicals) to be really effective and it doesnt stink.

Hi,

Modern fluorescent fittings with high frequency instant start control gear usually operate at about 30kHZ so are well suited for illuminating over lathes. And, now most people consider LED to be the new kid on the block, old style fluorescents are really cheap. Look for fittings that have T5 lamps (thats the skinny lamps). Also, reputable manufacturers claim up to 50,000 hours lamp life. And new style fluorescents are really efficient. As mentioned previously in this post, LEDs are not necessarily robust. Heat is the main killer and quite often the difference between a high end LED fitting and a cheaper one is heat management.
