LED GU10 Downlighter bulbs

LED GU10 Downlighter bulbs
I have just bought some GU10 LED bulbs to replace the Megaman Cold Cathode bulbs I did have in my kitchen.

A few years ago I tried some LED bulbs and found them to be rubbish but now, with the modern SMD LED chips I thought I\'d give them a go

I can honestly say I am really impressed with them. They really are extremely bright, brighter than the cold cathode ones I had and pretty much the same as a 50W halogen. The light is a really pure white too, not with a blue hint to it.

I bought four 7Watt, 48 LED bulbs and was so impressed I have just bought some more.

If anybody is looking to replace halogens with LEDs I would seriously recommend these

(you may need to select the relevant item from the lists)
I have nothing to do with the seller, just offering personal experience if anyone is looking for a suitable bulb.

They have built in electronics too so just fit straight into a 240V GU10 downlighter

yes, the modern leds are good, I fit a lot of sealed units as most come with a 10 year guarantee and are as bright as a 50w halogen

Just heads up for people, I do not know about these exact ones, but I have ran projects on LED bulbs. Testing them in accredited test houses against the safety standards. There really is a lot of dangerous ones out there, and they do look visually ok. I personally now would only buy from reputable retailers.

there is also a big problem with some of the florescent tube replacement ones, what happens with some is that when one end is fitted, the pins on the other end are live if the light switch is in the on position,

Some of the cheap LED lights have substandard reactive voltage conversion (just a cap in series with a rectifier). If you switch them on off enough and catch peaks in the mains cycle or have a dirty switch contact, the higher frequency just wafts through the cap and blows anything downstream (potential fire hazard). I\'ve had a couple like this. And some that have been absolutely perfect as well. Luck of the draw what you get if it\'s eBay...

There was something about the spectrum of light the led use, too much in the blue or similar, that will damage the eyes and blind you creating a dark spot on the retina... Or something similar...

Not being an electrician, does the CE RoHS stamp imply that the dangers mentioned in the above posts would not be present?

Thanks for any insight....
