Lumen / Watt various lamps

how much energy I put into it and how much visible light do I get in return?

Outside of the color temperature and Colourfastness this is the main thing you want out of a lamp. You will often see an expensive lamp a higher luminous efficacy (lumens / watt) than the cheaper ones. Outside the lifespan, this immediately shows why ...

At present LED displays about as much light than a good TL5 fluorescent or discharge lamp CDM. Thus, as a substitute for a fluorescent lamp or PL, it is interesting (if one want to maintain the light level) to apply LED. As for incandescent halogen lamps -and it is highly advisable to replace them with LEDs!

Also a very good application for LED coolers and freezers, here LED is certainly interesting as a replacement for a fluorescent seen LED does not suffer from cold. Here is a little table with different lights and the values ​​thereof. This at an ambient temperature of 25 degrees.
