The word "transformer" was for many years used to describe a wire wound device which would transform the voltage, there were current transformers, but they were for specialist use, only seen them as a power supply for aircraft runway lighting, and were often called drivers, but the lighting industry likes it seems to describe a new device using the old name, so we have transformers, power supplies, and drivers which often do the same thing, but one has to carefully read the description as the names seem to swap around.
As far as I can tell, the Philips Hue uses a 24 volt DC supply, I personally would not call that a transformer, although it clearly does transform the supply. A google found me a 100 watt version with two output connections, but seems odd as most the strip lights are 20 watt, so would have expected five output connections.
I have TCP and Lidi strip lighting, and they can be cut and a non illuminated joint used to span an area not wanting to be lit, but the 20 watt of power needs to travel through the strip, so even if a 40 watt power supply was available it would likely overload the strip as it passes through it.
So if you need to have three 20 watt outputs from the power supply, one has to ask why not use three independent power supplies? Combining into one big supply seems pointless.
Mine I thing have 6 tracks in the strip, which I assume are return, high colour temp, low colour temp, red, green, and blue. The total the strip can put out in watts is something like 60 watts, but it would burn out at this power, so the controller will not allow full output on all together, both makes are similar, so would expect to find this is a common way to ensure the strip and power supply are not over heated. That return track carries the current for all the LED's what ever colour or colour temperature they are.
Mine cost around £25 each, and I would not want to do anything which would result in them needing replacing, on Amazon I found a 100 watt "transformer" labelled as being Philips Hue, at £80, but it is shown powering uplights, wall lights, and spot lights, not strip lights, the advert is here
https://www.philips-hue.com/en-gb/p/hue ... 9514414273 however in around 2015 I decided to use Philips CFL golfball bulbs in the living room and dinning room, up to then I had considered Philips as a good make, but it seems they were no longer a good make, and the bulbs had to be all replaced within a year when spec said should last 5 years, they it seems are no longer Dutch, but Chinese, and not good Chinese either, so I now keep away from Philips, it is over priced tat in the main. Pity they were good. Have V2000 video for years, the best of the three. But now living on their name, but no longer the good quality they were.
