Ordinary Bulbs / CFL's
This is a guide to the difference between the power output of an ordinary light bulb compared to the power output and brightness achievable when looking to convert to an energy saving or energy efficient light bulb. Some Megaman products have a different equivalent wattage output due to their extended life so be sure to check on each product's individual landing page where the exact difference is shown. Please note that this chart is not valid for LED wattage equivalents.
Standard Wattage Energy Saving Equivalent
40 Watt = 7 Watt
50 Watt = 9 Watt
60 Watt = 11 Watt
70 Watt = 13 Watt
75 Watt = 15 Watt
90 Watt = 18 Watt
100 Watt = 20 Watt
110 Watt = 23 Watt
125 Watt = 25 Watt
150 Watt = 30 Watt


The colour temperature of a compact fluorescent lamp, more commonly known as an energy saving light bulb or energy efficient light bulb, defines the colour output of the lamp itself. You will notice that each lamp has either a colour reference or figure with the letter K next to it.

What does this mean?
A traditional incandescent lamp will put out the equivilent to 2700K which is about as close as you can get to the yellowy glow of a normal light bulb.
2700 Kelvin Extra Warm White - Traditional light bulb
3000 Kelvin Warm White - slightly less yellow
3500 Kelvin White - sort of speaks for itself!
4000 Kelvin Cool White - losing the yellow and replacing it with a blue tinge
6000 - 6400 Kelvin Daylight. Fantastic for sufferers of SAD or people working in offices. It replicates a cold, blue daylight feel. We use them in the offices for ebulbshop.com which is why everyone here is so happy!!
