"We all know what we get from a 60watt light bulb right? 60watts tells us how much energy it consumes, we know what the light will look like in terms of brightness and colour. LEDs and fluorescents also are different
It says 1.2W so it means 1.2watts v. low 4000k is colour temperature & that's cool white verging on blue 20.7Lm = 20.7 Lumens that isn't bright (as a Halogen Dichroic may be 1000-1500Lm)
It would help if the description were more, err, descriptive!
Very low power consumption (only 1.2watts) Very low output only 20.7Lm (For decorative use) Colour temperature 4000k (bluish White)"
"I like these, but probably wouldn't recommend them. Though they are the same size as halogen bulbs, these lamps aren't a replacement. They don't cast nearly as much light - you probably need at least four times as many so the installation cost is very high in comparison. Over a number of years, the lower power consumption ought to repay you. The light they give is a cold, bluish white, which is interesting in the right application. You need an LED controller to use them - a halogen transformer won't do."
