I would like to present my latest project. You will see that this time I went a little different way than usual. This project is a book example of reverse engineering of the product. I based it on an outstanding quality GU10 light source made by a well-known Polish Niviss company.
Below, you'll find the original, base product DS:
https://www.niviss.com/product/attachment/38783/nGU10.pdf
The radiator is made of numerically machined aluminum with a large margin of capacity in relation to the power with which the source works. Total active power taken from the 230V grid is 4W (after heating, the average power for basic color options is 3.8W). The temperature reached by the heat sink after heating at room temperature is ~ 50 * C. Onboard driver is equipped with the isolated and very fast output (frequency 60-70kHz) which means a complete lack of tiring eyes flickering LED source (strobo / flickering effect). The power system has high-quality components (including the Rubycon BXC series electrolytic capacitors)
I used 3030 Liteon Opto Series AQL and SL medium power LEDs (for special options) with high CRI min. 90. Liteon is a well-known producer of excellent quality LED emitters (one of my archived products based on AQL CRI emitters min. 90 on the spectro-photometric test achieved the result of 95 CRI). MCPCB made by MR Elektronik based on aluminum core laminate with a ceramic dielectric (3W/mK).
The two-structured diodes, The Liteon 3030, are connected in the 2s2p topology and supplied with a current of 140mA per emitter. An isolated driver gives the output ~ 11.5V voltage and current 280mA which gives the power ~ 3.2W with which the LEDs work. The measured efficiency of the inverter is ~ 80% with a power factor PF = 0.6 Optics – textured reflector. Wide angle of total emission approx. 120 *.

I would say go with the powermodule cause a t5 and led combo is the best.
