105w Warm White Bulb (BC)
"Shock and Awe" might well be the best way to describe this range of lamps.
At 105w this is a low energy lamp that produces a lot of light. Think small-sun, amounts of light. OK so maybe that's exaggerating a little, but this lamp is the brightest low energy lamp we have ever seen. It blows everything else out of the water. With the consumption of just over 100 watts of power this lamp produces 6800 lumens, which is roughly the same as a 500w incandescent light.
If you need a lot of light for any reason, this is the lamp for you: Visually impaired people, photography studios, artists, animators - you have to see this to believe it.
The only downside is the size - at 300mm long and a maximum diameter of 100mm (the glass tube part of the lamp) it's not a small lamp, but more size equals more light.
The plastic base is slightly narrower at 87mm.
Comparing light bulbs
When you're comparing light bulbs to decide which one to buy, remember that light output is measured in lumens. Some bulbs produce more lumens for the same amount of electricity (measured in watts), which means that not all bulbs of the same wattage are the same brightness.
