Medical Forum / General / Vision / May 2008Full Spectrum Lighting
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. > I prefer to stare at the sun for an hour a day.

And don't forget, with just the right combo of drugs and alcohol, one can split that spectrum into really neat colors. > > > I prefer to stare at the sun for an hour a day.

So did anyone try out full spectrum lights? Any serious comments! > 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 sh.t, 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. > 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'!

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. -- Ron 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! > In the future I think everyone will be using these bulbs (for > conservation of energy etc.). So you might as well switch now!

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. -- Ron OK, but can you get full spectrum LEDs? > OK, but can you get full spectrum LEDs? Sure. And they don't have mercury in them. -- Ron >> OK, but can you get full spectrum LEDs? > > Sure.

The > futuristic world is a bright, white one! 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. > Eastern countries (such as Bangladesh) are already using these bulbs. > It's western countries that are slipping behind in the technology! 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 f.cks up one's natural cycles no doubt.

SignatureDan Abel Petaluma, California USA dabel@sonic.net Hi Pramesh, thanks for the message. It's actually really easy to get used to full spectrum lights (it took me only 5 minutes) in fact I enjoyed it so much more than incandescent that I think 'getting accustomed' is not even an issue. About it affecting your natural pattern, well from personal experience I can say these bulbs have improved my sleep. I don't think they have any negative affects. I am thinking of getting some LED lights for my home now after reading you and Ron's messages. Do you know what the price is for a 150 watt equivalent, also do you know where I can buy them? And will they work with the Bayonet fitting which I have in my home? Or do I need a special type? Hope you will answer these questions. Merci xD > Hi Pramesh, thanks for the message.

I have tried some full spectrum lights and didn't care for them. I have a full spectrum light designed for use in the winter. I tried it for a while but it did nothing for me. > About it affecting your natural > pattern, well from personal experience I can say these bulbs have > improved my sleep. I don't think they have any negative affects. Depends on when you use them. Full spectrum light when you should be winding down, melatonin should be increasing as your body prepares for the night will mess you up over time. > I am thinking of getting some LED lights for my home now after reading > you and Ron's messages.

You will save 80% with full spectrum fluorescent lighting! In fact over time, they pay for themselves! Incandescent is a waste of money and energy because it gives off lots of heat with relatively teeny amount of light. You will spoil the environment if you use those old bulbs (halogen, incandescent) because they give off some carbon dioxide emissions and pollute the atmosphere! >> No, it's not a matter of slipping behind, it's a matter of cost and what >> one is used to.

They burn out to easily, much sooner that they claim, and they get duller with time which is unacceptable. Their lumens need to be constant over time and they often are not. > In fact > over time, they pay for themselves!

My electric bill is only a couple of percent at most for light. > You will spoil the environment if you use those old > bulbs (halogen, incandescent) because they give off some carbon > dioxide emissions and pollute the atmosphere! Tweedledee, Tweedledum. I could walk everywhere, live in the mountains in a cave, and eat off the land too. I'm sitting in my den right now where there are 6 60 watt lights and 4 150 watt lights that are florescent and 6 65 watt lights that are incandescent which means they can work with a dimmer. I have two fans going in an air conditioned home because I like the air moving. There are seven computer monitors functioning with several computers that run 7*24, and a very large TV. That's only my den. I own a very large home, more than 5000 sq/ft, with a lot of people who all have computers, tvs, etc. Does it seem like I'm worried about saving a couple of pennies on lighting? My den has the more florescent lights than the rest of the house but I have to change them almost as often as the incandescent lights. Most of the lights are can lights and florescent has a lot lot lot shorter life in such a fixture. As they burn out, I'm putting incandescent back in. I do like efficiency not because I'm an environmentalist but because I like to be independent and self sufficient. I looked at geothermal for heating an cooling my home, I have investigated solar and energy storage so that I can be off the grid, I have looked at wells, pumps, etc., etc., with the plan to design my own home someday that is large and spacious, well apportioned, on several dozen acres with woodland and farmland and completely off the grid. Reducing my "carbon footprint" is the least of my concerns. SignaturePramesh Rutaji p297tongue6221@newsguy.com - remove tongue to reply > ... I get a slight buzz... well that explains a lot. I wonder if full spectrum lighting can cure Fuchs?
