Low Energy Lightbulbs
Posted: Fri Dec 22, 2006 9:02 pm
As there are a perplexing number of low energy lightbulbs on the market, at a wide variety of prices, I've been trying different ones out. I thought it'd be a good idea to have a thread reviewing them.
I can't bring myself to call them 'energy saving', despite that being what they are sold as - they don't save energy, they just use less of it. In use, the most noticeable feature about them is that they all have a warm-up time, starting off being quite dim, and then getting brighter during the following half minute or so. Trust me - you get used to this very quickly, and it isn't long before you hardly notice it. I was also surprised at the difference in the quality of light; it is subtly different from a filament bulb, but usually not at all unpleasant - just that things are a slightly different shade of colour. Again, you soon hardly notice this.
Feel free to add your own reviews or comments.

MAKE: Philips
MODEL: Genie
WATTAGE: 11 & 18W
CLAIMED EQUIVALENT FILAMENT BRIGHTNESS: 60 & 100W
TOTAL LENGTH: 115 & 130mm
CLAIMED LIFESPAN: 6 years
PRICE: Dunno - given to me
WHERE BOUGHT:
DATE:
COMMENTS: These are probably as good as any of the current bulbs available. They are pretty dim at startup, but with a fairly quick warmup to full brightness (30 seconds-ish). Fairly compact with 3 and 4 fluorescent loops. Not sure I'd say they were quite as bright as they suggest they are.
MAKE: Philips
MODEL: Stick
WATTAGE: 20W
CLAIMED EQUIVALENT FILAMENT BRIGHTNESS:
TOTAL LENGTH: 135mm
CLAIMED LIFESPAN: 12 years
PRICE:
WHERE BOUGHT:
DATE:
COMMENTS: Bulkier than the Philips Genie bulbs, with 3 fairly big fluorescent loops. A bigger and slightly brighter bulb, but otherwise see comments above.
MAKE: Pearl
MODEL:
WATTAGE: 11W
CLAIMED EQUIVALENT FILAMENT BRIGHTNESS: 60W
TOTAL LENGTH: 140mm
CLAIMED LIFESPAN:
PRICE: £1
WHERE BOUGHT: PoundLand
DATE: 10/06
COMMENTS: Horrible, cold quality of light, but most significantly, these have an unacceptable, headache-inducing flicker to them. Really awful. They were only a pound each, but I was robbed.
MAKE: Oasis
MODEL: XM25
WATTAGE: 11W
CLAIMED EQUIVALENT FILAMENT BRIGHTNESS: 60W
TOTAL LENGTH: 140mm
CLAIMED LIFESPAN:
PRICE: 99p special offer
WHERE BOUGHT: Wickes
DATE: 09/06
COMMENTS: Good light to begin with, and half a minute-ish to full brightness. Doesn't seem to be quite as bright as, say, the equivalent Philips Genie, and has two fairly long fluorescent loops.
MAKE: Ring (Focus' own brand)
MODEL:
WATTAGE: 20W
CLAIMED EQUIVALENT FILAMENT BRIGHTNESS: 100W
TOTAL LENGTH: 160mm
CLAIMED LIFESPAN:
PRICE: £1.99
WHERE BOUGHT: Focus
DATE: 11/06
COMMENTS: A long bulb with three fluorescent loops. There is a disconcerting moment's delay between flipping the switch and the bulb lighting up; this seems to result in a fairly good light at startup, but it doesn't seem to get much brighter. Not particularly bright for its wattage - in fact I'd be surprised if it was as bright as a 60W filament bulb, let alone a 100W. Also, it hums; not loudly, but in a bedside lamp, too loudly.
MAKE: Wickes (own brand)
MODEL: Energy Saver
WATTAGE: 12W
CLAIMED EQUIVALENT FILAMENT BRIGHTNESS: 60W
TOTAL LENGTH: 115mm
CLAIMED LIFESPAN: 6,000 hours
PRICE: £1.69 (special offer - half price)
WHERE BOUGHT: Wickes
DATE: 12/06
COMMENTS: This is about the size and shape of a filament bulb, without any of the loops of tube that most of them have. Good quality of light, starts off pretty dim but gets brighter over the next minute or so. Probably as bright as it claims to be. But I can't forgive the meaningless claim on the box "Uses 5 times less electricity". I presume they mean to imply that it uses one fifth of the electricity compared to a similarly bright filament bulb.
