I have slowly been converting all the light bulbs in our house from tungsten filament to LED and I have purchased from a wide range of sources - ebay, local garage, discount shops etc and they have all worked fine. Today I happened to be in B&Q so purchased four 5.5W bayonet cap candle shaped bulbs to fit in some wall lights in our conservatory. Unlike my previous purchases all of these new bulbs exhibited a pronounced 50Hz hum and had to be taken back. Has anyone else had this result?
I recently had a bathroom redone and it has 12 GU 10 bulbs. Halogen were hot, and I have replaced them with “Cree” LED’s - 5w = 50W , glass housing ,”warm white” from Wickes. They have a central orange/ yellow bulb so the light is excellent- not blue at all, and they are cooler than halogen, and hopefully far longer lasting.
Some interesting comments but in response to wee eddie I have since replaced the B&Q bulbs with some purchased at a local discount store called Buyology (don't know if this is just a local Plymouth store or a national chain) and put them into exactly the same light fitting. No buzzing heard at all now so to my mind it is a feature of the bulbs and not the fitting. Incidentally the fixture did not buzz when it had tungsten bulbs either. I paid £5 each at B&Q and £2.20 at Buyology, same wattage same bayonet cap fitting.
I purchased four bulbs from the rack at B&Q, all the same brand, all the same wattage and all four were tested and exhibited the same humming noise, which is why they were returned for a refund. The shop assistant was told the reason for the return. Was it a bad batch? Are they all faulty? They all lit up fine. What I do know is that four different bulbs from a different store, same wattage light up and do not hum.
I will close this thread, it is just meandering on and all I really needed to know was if anyone else had LED mains powered bulbs that hummed. Thanks to all for their comments.
I have 2 LED lamps in use at the moment. One is an SES 3w spotlight as a replacement for a 30w Tungsten one. Much brighter lamp with a 3000k colour temp. The other lamp is a 10w LED in my living room standard lamp. Again 3000K. The light is a little whiter than the old tungsten lamps but certainly not blue. You need to pay attention to the colour temp. The higher the number the whiter/bluer the light. I've had no problems with buzzing although I initially had problems with the bulbs not lasting very long. These were replaced by the Amazon seller and have been OK since.
