I find the big problem with inferred is so hard to quantise the effects. One would need a flesh coloured receptor to measure the effect, and it would need to have a standard amount of moisture a kind of wet/dry reading to work it all out, and it would only be valid for the person it is modelled on. Lighter or darker skin, damper or drier skin, and the results are invalid.
However an Anglepoise Lamp one would think would be reasonably close.
Clearly a thermometer is not going to help, but I do know we had no problems with a programmer turning the central heating on/off and a single temperature thermostat regulating the temperature until the 6 x 60 watt tungsten bulbs were changed for first 6 x 11 watt CFL, then 10 x 8 watt CFL, then 10 x 3 watt LED and finally 10 x 5 watt LED.
We noted we felt cool in the evenings, during the day we were active, so 18ºC was fine, and with 360 watt of tungsten bulbs the central heating temperature at night was not altered, but as we dropped to 66 watt we noticed at night it was cool, and also seemed dimmer. So thermostat swapped for a programmable type, and in the evening we went to 20ºC.
The biggest problem was moving to Philips golf CFL as we also went from 6 x BC22d to 10 x E14 so could not return back easy, and the 8 watt bulbs would start with orange glow and slowly get brighter, but were never bright enough. So 66 watt to 80 watt and the result was a dimmer light.
However the move to 10 x 3 watt candle bulbs seemed brighter, however we could not read a book, hence change to 10 x 5 watt.
But I look are one area of the kitchen which was 65 watt fluorescent brighter than required, went to 58 watt fluorescent still a little brighter than required so going to 22 watt LED was fine for that area of the kitchen, son did not like the fitting so swapped it for 16 x 3 watt GU10 lamps, nearly back to the 58 watt of the fluorescent tube, but no where near as bright. I assume as not being reflected off white ceiling.
However same 3 watt GU10 lamps are fine for reading lamps, and one does wonder why anyone would use a 100 watt tungsten in an Anglepoise Lamp. The lamp is best suited to a directional lamp
I have always used a reflector bulb as other wise the shade gets too hot, I went to website to look at max bulb size, actually took some finding, but does not give it for tungsten bulbs, it simply says
Bulb included: Yes
Bulb type & rating: 1x E27 LED – 6W
Bulb output: 470 Lumens / 2700 Kelvin
Bulb lifetime: 15,000 Hours use
Bulb replaceable: Yes
Max Bulb Rating: 10W LED E27
Dimmable: Yes - Additional electrical hardware required
that seems a lot short of 100 watt tungsten, I would normally use a 40 or 60 watt reflector bulb.
tends to be mounted on a printed circuit also designed to remove heat, putting a globe in front of the chips be it candle or bulb shaped, will to some extent defuse the light, but still most goes forward in the direction the chip is pointing.
have a spread more like the tungsten, but often a clear bulb, so not defused as with a pearl bulb, so it really matters as to orientation of the bulb.
shine up to white ceiling and are reflected from the ceiling giving a reasonable shadow free spread, but reverse it as with this 
example and to get the spread the fitting needs to be high, this one over the stairs, the dangling bits do defuse the light a little, but not really enough, however it was got to look nice, more than to get the light required.
rated at 24 watt, 2452 lumen is going to emit far more light to a 100 watt tungsten, but one £12.49 and two the wrong direction, we can google it for you but sure you could do the same without the link.
one it shows although a candle bulb, all LED's face away from base, but also second picture shows the reasonably large smoothing capacitor which should stop the strobe effect.
