I want to tell everyone what a huge difference full spectrum lighting
can make. I bought one from Ebay recently and ever since my room has
been filled with a wonderful white glow. It's economically and
ecologically friendly as well, taking only 30 watts to produce as much
light as a 150W incandescent bulb would. And it lasts 8000 hours
compared to the normal 1000 hours.
Has anyone else tried full spec lights?
If you haven't, I totally recommend trying it. Not only does it
improve your mood and health, but cuts down the electric bill. If you
buy one, make sure it says 'CRI>95' and that the temperature colour is
6000 minimum (anything under and you won't get the proper 'white'
feeling), and one that has a luminosity of at least 1200 lumens.
The white glow it pervades is instantaneously relaxing. Walking from a
room with normal yellow lighting into that - the difference is just
remarkable. It's also a good favourable condition to work with the eye
charts in, because it renders the blacks in a truly vivid black that
you can't get with normal bulbs.
They are also ideal for gazing directly at (the stronger the better).
If you are living in the UK, just ask and I can tell you some good
links for where to get them. |

I prefer to stare at the sun for an hour a day. The light stays stored
up and I don't need any lights at night at all. |

Nice!
And don't forget, with just the right combo of drugs and alcohol,
one can split that spectrum into really neat colors. |

Wayyyy ahead of you. |

So did anyone try out full spectrum lights?
Any serious comments! |

We're always serious when commenting on your posts.
Generally, you're full of shit, but don't realize it. |

Well, I saw an 'ioniser 32W' full spectrum bulb on amazon a while ago
and it looks really good. I think I will buy it (£10). Colour
rendering index of 95 and colour temperature of 6000 kelvins (noon
sunlight). Brightness of 1800 lumens, very good. To top it off, it
freshens the air! The downside is that most of the sockets in my home
are 'dimmer type' which means that I get a slight buzzing noise
(hardly noticeable if you have the TV on or something, and eventually
you get used to it). And I've heard that the ioniser makes a buzz
too.
My home already looks like completely sunlit, you would think it's
daytime if you didn't look at the clock dial showing '23:45'! I'm
going to give full spectrum bulbs to all my relatives as a gift so
that they can enjoy it too. |

Fluorescent bulbs may not be that well color balanced although it may
appear to be at first glance. A spectrometer will usually show strong
green bands from the mercury vapor discharge.
What is helping your vision the most is the greater blue content of
the bulbs which causes your pupils to narrow giving you sharper
vision.

In the future I think everyone will be using these bulbs (for
conservation of energy etc.). So you might as well switch now! Because
they pay for themselves over time in comparison to the amount you
would have paid for an incandescent non-energy saving bulb. The
futuristic world is a bright, white one!
Eastern countries (such as Bangladesh) are already using these bulbs.
It's western countries that are slipping behind in the technology! |

The future of lighting is in LEDs which now are being used in traffic
lights, but will move to indoor lighting as well as flat screen
backlighting.

| OK, but can you get full spectrum LEDs? |

Sure. And they don't have mercury in them.

well that explains a lot.
I wonder if full spectrum lighting can cure Fuchs? |

First of all, I use a lot of them and they don't last near as long as
they claim. They also grow duller after a few months. Put one in the
fan light and they wear out even faster from the constant movement of
the fans. In my area of the world where it goes below freezing in the
winter months, florescent lights turn on slower and take several minutes
to warm up to full light. I have three 300 watt equivalent florescent
lights in my garage and it is still not that bright during the few
minutes one uses the garage in the winter time.

No, it's not a matter of slipping behind, it's a matter of cost and what
one is used to. Incandescent lights provide a light I'm used to, the
cost is really cheap, and I've had electricity all my life so I'm used
to it. I couldn't care less what Bangladesh uses for their one light
bulb per hundred people and where electricity is no where near as
prevalent (and exaggeration, perhaps). If price was no object, I would
be using LED lights - now that's energy efficient!
I would prefer a light source that mimics the spectral changes in the
sun from sunrise to sunset with very low light levels before sunrise and
after sunset would be ideal. A full spectrum light when your replying
to email right before going to bed fucks up one's natural cycles no doubt.
