My understanding is that LEDs have a very specific, peaky distribution. Heating a wire results in a wide distribution of color temps, but solid state lighting is a really narrow band of color. I have a photo panel that needs two separate color LEDs to produce a balanced feeling color temp.

As I wrote (https://news.ycombinator.com/item?id=19919819 https://news.ycombinator.com/item?id=19919819) LEDs usually have a single color: blue. However the resulting spectrum generated by the phosphor can have almost any shape, some high-quality LEDs even have a pretty perfect black body spectrum without a blue line. Of course they are more expensive and also less efficient.

    In terms of commercially available bulbs, the 'Philips Master LED ExpertColor' (all in spotlight 'GU10' etc. format) have an extremely high quality halogen-like spectrum.

    Search for "high CRI LEDs". This should turn up LED module vendors which usually have the data sheets which should include a LED spectrum. The warmer the LED temperature is, the smaller the blue peak. For example here: https://www.led1.de/shop/files/Datenblaetter/Osram-OS/Oslon/GW_CSSRM1_BM_-_OSLON_SQUARE_CRI_95__EnglishDeutsch_.pdf https://www.led1.de/shop/files/Datenblaetter/Osram-OS/Oslon/... or here https://lumstatic.com/9p/Vt/uRNvyjbnQnfzzgO6rg.pdf https://lumstatic.com/9p/Vt/uRNvyjbnQnfzzgO6rg.pdf.
