My first post. Thought I would repost the deal from last week as they were oos. Just ordered.

Or you could just do the math... assuming replacing 75w bulbs:
75w-8.7w = 66.3w (energy saving)
66.3 * 15,000hrs = 994500wh (watt-hours, over bulb lifetime. Assuming 8 hours a day, that's 5~ years)
/1000 = 994kwh (total saved energy usage in kwh)
994kwh * £0.1 = £99.45 (assuming rate of 10p/kwh, conservative)

£99.45 * 5 bulbs = £497.25 (total saving with 5 bulbs)
So yes, hundreds indeed. Perhaps before you start being condescending and patronising, check your facts first. Took me literally 1 minute to work out.
