These in the sense similar, made for Philips in China, the rest of the work is done here.
Older designs had a separate LED board and driver board...and cheaper designs used RC networks to drive the LEDs!


I can see the members from more advanced countries rolling their eyes...

NareshBrd, you seem well informed about these LED bulbs.

Mine is a broken Tesco 8.5W 2700K. It refuses to glow.

Using sophisticated tools I have disassembled successfully and now just need advice on where I obtain a new yellow coil before gluing it back together.

The yellow coil is clearly split and broken apart.

I suspect it is the INTEROCITOR coil. I would further guess, as a layman, the overall device is an "interocitor incorporating electron sorter" and "intensifier disk" combined. But could be wrong.

That is a Ferrite transformer, the old designs were like that: separate driver and LED boards. In a 9 Watt, the supply is constant current 27V.

For 20p I would not bother, just keep aside for when another pops with a different fault. Then mix and match...check that the LEDs are OK.

I have supplied LED flood lights, bulbs, panel lights, and filament LEDs as a trader, and have had a reputable run, because I sold A quality material, with wide band supplies and surge protection.

Here the government had a subsidy scheme, gave millions of bulbs at cheap prices to users, with a three year replacement guarantee.
Poor people could make part payment over six months.
So these suppliers were in contact with my importers, and I had knowledge about what was happening.
Supermarket price for 9 watt bulb is less than 100 Rupees, Philips T bulb is 10 Watts, about 150 Rupees.

1 Rupee is about 1 UK penny at this time.

Closer inspection of the coil reveals it looks like some vandal in the factory sawed through it with a hacksaw!

Can't imagine how else it happened...

Think I'll just give up.

I prefer this

I have some Phillips, but most of my LED lights are 4$ Chinese from eBay. Never had one fail in 5 years not that they are lit up a lot.

My main lights are now "Smart" bulbs that can be RGB, Warm, cold, or a blend between warm/cold. These ones are 12$ a piece but I can turn off the lights from another country lol

They are cold in the day, warm 30 minutes before sunset, and the I turn them red at night.
