A look at the insides of an ASDA branded LED lamp. I noticed they seemed to be clearing out their stock of certain ranges and doing the same with the overpriced Duracell branded lamps too.
First surprise was the thickness of the plastic LED cover. So thick and solid that I thought it was glass with a protective coating. Perhaps that's part of the heat dissipation system? The cover was removed (with extreme force) to reveal a universal potted module inside with the array of LEDs mounted on a mtal core PCB which was then mounted on a stepped aluminium plate and then an aluminium shell that contained the circuitry potted in an easily removed white rubbery heat transfer compound. The only components protruding from the module were the capacitor and fuse. Presumably to keep the electrolytic capacitor away from the heat and also to allow the module to be used in a wide range of narrow bases.
The circuitry looks like a buck regulator and uses a chip with the following three numbers on it:- TCP1213 (possibly a manufacturer and date code)
CDO8617
TnD3221
I couldn't find any data on the chip online. I presume it may be a standard regulator chip but with custom markings.
Actually quite a neat lamp.

That's an amazingly eleborate LED globe, it even has a chassis.
The good-old 480p 10fps YouTube videos…
I am late seeing this one. Hoping you see my comment. Have you ever "taken to bits" a Lohas LED bulb which I have had really good luck with.
I run on ASDA lamps as it's just across the road and they were dirt cheap for me at the time, 2 for a fiver or poss 8 quid, but absolutely dirt cheap to run. I use 0.2 to 0.6 unit a day now in total of electricity.
Clive, So sorry about Walmart. Here they tend to run all the local stores out.
Hi Big Clive. Love your channel. Having purchased 3 of GE 7 watt CFL SES bulbs for my kitchen light from Tescos I have been amazed as the first 2 bulbs have gone long ago maybe 2 years after purchase. I think I purchased in 2013. The third one is mind boggling and is still working to this day. Could you do a video explaining this. It glows pink on start up so thought it would be suitable for your channel. Lol. I'm amazed and confused as to why this one is still working 2 years after the other pair have been assigned to the black bin of death. Lol
For a couple of months now, Tesco have been doing a 100W equivalent LED for £7. For £8 they have a dimmable 100W equivalent.
I've bought one of the non-dimmables. Light output is good. It runs hot. The shell is too hot to touch for more than a second or two. I'd love Clive to do a tear-down and give an opinion on the innards before I spring for another. Maybe a Y-adapter and two 60W equivalents is a better way to go.
i prefer globe lamps to candle lamps. they appeal to me more.
So that's the face?
I wonder if the TCP1213 could be related to TCP-branded lamps (as can be found in Homebase)?
ASDA, as I am sure you know, used to be ASsociated DAiries.
Love your videos but over the shoulder is a better angle and seems sharper.
I was surprised to find 60 and 100W incandescent lamps on Amazon. The CFL's we have just don't cut it. By the time they have warmed up you are in bed :)I am trying a LED G10 lamp now in a spotlight.
