We are steadily replacing old incadescent, CFL and halogen bulbs in our house with LED bulbs. They tend to be the 2700k for the warm colour. We tried the daylight colour ones but they were too bright.
From my standard grade physics I know that LEDs are low powered devices that need direct current so does an LED bulb contain a transformer? Even at 5 volts an LED needs a resistor inline, so do they all contain resistors as well? Could these components wear out in an unsafe way? I only buy the bulbs from supermarkets like Tesco, Morrison's or Sainsbury's. They're CE marked and seem to be well made. I don't buy them from eBay or Amazon. In the bedrooms we are currently using Philips Genie 40W CFL bulbs but when they wear out we might replace them with LED. All circuits are MCB and dual RCD protected.
First of all we fitted a 5.5W (40W equivalent) one at the top of the landing for instant light. It was hard to access because the stair case is curved so we wanted something that would last a long time. It has been running for 2 years fine. We also fitted one in the bathroom and that works well. That replaced an old torroidial transformer track light that we couldn't get a replacement transformer for. Scottish Gas homecare had to qualms about installing them. The bathroom one has a strange shaped holder for protection I think.
From a health point of view we tried LED spotlights at work but we could work under them for a full day because they were too bright. One colleague who suffers from migraine also complained about them triggering headaches. We ended up using standing lamps with halogen bulbs. I don't want to install anything that could be electrically unsafe or harmful to the health of my family's eye sight.
