The new warmer white GU10 lamps in Poundland claim to have a higher light output than the cold white ones. (I'm not convinced they do). But lets check out the PSU anyway.
One moment please…

i have this light bulb and its having a horibble flicker
They're selling a 5w GU10 now.
I am amazed how it's possible to build a power supply in a milion ways 🙂
Dear Big Clive, thanks for all your interesting videos.
I was hoping you could test a IR thermometer against your thermal cam, if it can take close-ups.
I use IR thermometers to try to see the junction temperature(the relevant measurement for me) of many types of high power LEDs.
Simply taking pictures of some 0.5W 1W 10W 100W and comparing to holding the thermometer directly on top of it, what do you think?
Could be a great video, thank you for your time 🙂
I don't like any of the energy saving lamps they all give off RF rubbish in my opinion Incandescent light bulbs for me all the time .Another great video thanks for posting
Nothing more entertaining then seeing a grown man scream like a girl when he gets that white sticky stuff on his fingers 😛
I bought three LED GU10 lamps yesterday, rated 5 watt (allegedly equivelant to a standard 50w lamp) to replace the halogen GU10's in my bedroom light fitting. I got them from Lidl and I have to say I was pleasantly surprised at how nice and fairly bright they were for a five LED warm white lamp.
Clive, you should do a show on how to smooth out those cheap power supplies so the LEDs dont flicker as badly on video.
Is the silver LED holder bit metal? I asks as the mains to secondary side clearances on the PCB are no where near enough for safety.
Is it possible that the heat sink may become live due to the pcb not being epoxy potted or at least heat shrinked. Bloody cheap Chinese junk.
And that's why I refer to it as heatsink spooge… 😛
It may also be that the figures for the warm white LEDs are slightly newer, and maybe the chips have gotten a few percent more efficient since the labels were made for the cool ones.
Of course, it's probably still just marketing wank.
It may be important to note that you need to be careful putting the screws back in on the LED board, I torqued one too much and twisted the head off and had to use the power of DRILL to liberate it. Anyways not the LED board has bigger stronger screws and it doesn't flop around in the casing which is why I took it apart int he first place..
IDK if this is a thing in GU-10 types but in the E27 types I found it a problem in a few now.
You do make me laugh clive, your reaction to heatsink grease lol 😀
Don't like sticky white stuff on your finger so? neither do I lol.
