[EnergyPlus_Support] Fluorescent Vs. LED

["alexvlachokostas@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Dear Forum,

I am modeling Fluorescent Vs. LED lighting in EnergyPlus (EP). 

In particular, I use the following values from the 'Input-Output Reference' EP documentation, for a surface mount fluorescent luminaire configuration:

-return fraction= 0, 

-fraction radiant= 0.72, 

-fraction visible= 0.18, 

-f_convected= 0.10.

1)

Does anyone know of any well referenced values for LED lighting? 

-fraction radiant= ?, 

-fraction visible= ?, 

-f_convected= ?.

 

2)

Also, if fluorescent uses X amount of power (Watts) how much less does LED use?

I found a lot of information on websites but not in a well referenced document.

Thank you in advance.

Best,

Alex Vlachokostas
