Removing the front glass of a GU10 is quite simple: when you “boil” the lamp in a thin layer of water (approx. 1cm) for 5 - 10 minutes. The hot water causes the glue to lose its strength and the glass can easily be pried off by means of a thin screwdriver or a knife.

What I personally do is I use a hair dryer.

Method worked well on Philips GU10. Took about 2 minutes before it popped off easily. Followed by 15 minutes of explaining myself to my partner why I'm boiling a perfectly fine Philips bulb.

They arrived at 5W by pulling the shenanigans that many generics do. Those seem to be 250mW LEDs, so they just did 18 LEDs x .25W = 4.5W + driver inefficiency or rounded up to 5W. Unfortunately they also often rate the lumens based on what they would have been at 250mW and 25C temperature.when the actual output is probably closer to 150lm.

i calculated power draw for this schematics and its 7.05Watt.. i dont get the 2.5W meter reading at 1:04, my manual says that under certain wattage it does not work properly.. edit: i forgot to involve power factor which tends to be around 0.5 for these crappy ones so it would bring theoretical value to 3.5Watts, close enough to your measurement with that device's uncertainity..

You forgot the equasions: For really shitty vendors Watts = ChinaWatts / 3 For less shitty vendors: Watts = ChinaWatts / 2

what's the purpose of the 470nf cap and 1M ohm resistor ? current limiting ?

+BillyNoMates1974 Yes. The capacitor lets through a fixed portion of current on each half cycle as the polarity changes across it. The resistor is to discharge that capacitor when the lamp is unplugged as otherwise you can get a zap off the lamps base.
