1 Watt or Less Efficient Led Light Project

Hi erfandl, thanks for the reply.
Both coil layers are wound in same direction, though that would not matter anyway, as they are separate coil layers.
I bought the ferrite toroids here: https://www.sciplus.com/ferrite-toroids-55644-p

Hi gyulasun, thanks for the reply.
The light fixtures focus seems to be well enough and is making a smaller area brighter, as you point out.
The circuit is oscillating at a fairly high frequency, as heard using my headphones close to the coil, so faster diodes for the bridge would probably help.
This is a project, so I plan to tweak and make inprovements where possible, keeping with the 1 watt or less input idea.
peace love light

How many tuns primary and secondary

thanks for answer. is layer 1 is under the tape ? or like the below picture ?

thanks

Hi ed, i did not count the turns.
Hi erfandl, the circuit drawing says it clearly, first layer is 1 full layer of 30 awg. magnet wire, which is on top of the ferrite core, with thick paper covering the core, then the coil.
The second layer is 1 full layer of 24 awg. magnet wire.
The tape or coil mess you see in the picture, is because the 30 awg. snapped on me while winding the first layer and i soldered and taped it together, so it is sticking out a bit in the middle area.

Edit: hmm, interesting, i placed another diode in parallel with each of the diodes in the homemade full wave bridge, specifically, 1n4002's, as i have no more 1n4004's on hand.
Surpisingly, the light output has increased noticeably, while the input dropped slightly.

thanks.  I understood. sorry for noob questions
