Ceiling Lamp

After my first project

https://www.instructables.com/id/LED-Box-Room-Lamp/

I moved onto the corridor lamp and using the same bits from the china lamp I stuck the led strips with the heat sink paste to the lamps steel casing.

I then linked the strips in series and as in my previous project used the china lamp inner's as supply.

Both this and the other lamp are now much more efficient and last way longer as they now have a heat sink to cool down the led strips.

I have also realised that no matter how many led strips I use the supply voltage changes to feed each led its 3 volts.

When I tested 36 led's the voltage measurement was 108v

With the same bulb inner circuit I then used 50 led's for this project and the voltage went up to 150v.

I don't know why but the voltage seems to increase with the amount of led's fitted.

I have also read that this circuit could be improved using a 100 ohm resistor at the positive side just before the first led strip as a fusible resistor and changing the dropper capacitor for an x rated capacitor.

This is something to try with my next lamp.

Anyone tried this before or have any experience with capacitance dropper circuits?
