School me on light bulbs! My lamp and overhead light bulbs just died, and I'd like to use the opportunity to rethink the type I'm using. I'm totally ignorant in this area, so I'll give as many details as possible, inside the fold....
I'm in the UK, if it matters. My lamp bulb is currently a Crompton 60W Triple Life Plus (can't find it in stock online, so no link). My current overhead bulb is currently a Philips Ambiance 20W
, which seems to have a color temperature of 2700 Kelvin. I'm not sure whether this is a halogen bulb, but apparently halogen bulbs are Very Bad, and we're meant to be switching to energy saving bulbs (I believe these are equivalent to Compact Fluorescent Lights [CFLs])? I found some bulbs of this type that look good
, and was perfectly prepared to buy them, and then I read some disturbing things about their carcinogenic potential
. I then looked into LED bulbs, which look awesome in that they seem to use even less energy, but I can't seem to find ones that produce very much light
Basically, I'm hoping that someone can explain the various types of bulbs and their pros and cons, as well as whether they can be installed interchangeably in my various lamps and overhead lights. If an LED or CFL light says, for instance, that it is 30W but produces 110W worth of light, I can put it in a lamp that advises not to use a bulb more than 100W? Is there any advantage to buying a special (and expensive) "daylight lamp"
, versus simply buying a daylight bulb for my existing bog-standard lamp? What's the difference between watts and lumens?
Special snowflake details: I have SAD and live in England where the days are often gray, so I'm looking to have my room as bright as possible, and I much favor things that mimic natural daylight rather than something too orangey. I'd also prefer to avoid cancer as much as possible, especially from my light bulbs. I read in my room for 10+ hours a day. At home I have a lamp that seems exactly like this one
, and I LOVE it. According to the website, it's a CFL bulb of 27w that feels like 150 watts. I like the clear, intense, steady light it provides. This makes me worry that LED bulbs won't be bright enough. I have a large room currently illuminated with two overhead lights hanging from the ceiling, with shades, as well as a lamp on my bedside table. I believe all of my light fixtures use bayonet bulbs that are standard sized. I'd be prepared to buy more lamps if the consensus were that I should get lower wattage and more lamps. I don't pay for electricity (included in my rent), so a dramatic savings in electricity bills isn't on my priority list, although I like to help the planet as much as the next liberal. In short, I'm totally confused about what my options are. I see a couple of old Ask MeFi questions, but am hoping the products have improved in the past several years. Help me before I blow a fuse!
