For new genie bulbs it's about 3 seconds, there used to be a 30 second rule.
because you have 3 or 4 loops on these genie bulbs, that's what delays them to get to there potential. If you tried the tornado bulbs which holds a single spiral tube then these are instant (after an initial few times of use).
No sorry, all new bulbs on the market should use the 3 second rule. the 30 second rule is the older type of bulb which most people think of when the hear about energy saving, these bulbs are no longer available (in most shops)Sorry, are you saying some of the new energy saving bulbs don't take 20-30 seconds to reach their full brightness?

well I'd honestly say that if you want to dimm any bulbs, then use the eco classic style. These bulbs use the halogen based G9 bulbs and are better for the increase in electricty, also these bulbs can be used in touch lamps.
with what I was saying ealier, halogen based bulbs produce about 30-50% more light for their wattage. What the manufacturers have done now is calculated the actual output and worked back so that the extra light is now a saving, hence the eco classic based bulbs.
For the eco classic 30's you can get 28w/40w - 42w/60w - 70w/100w and 105w/150w
for the eco classic 50's I've only seen 20w/40w - 30w/60w
G9's are also available as 28w/40w
I personally don't trust them and they won't last no where near the life span they state yet.
the cfl bulbs were never intended to take varying amounts of electrical input but the halogen bulbs are proven in my opinion.
Far too bright anyway. 60w is where it's at.
lifespan - measured in either hours or years(1,000 hours is equivilant to a year [equals on average 3.3 hours a day])
