Lights Out

Lights Out

How to tell which light is burned out on Chritmas lights?

Is there an easy way to figure out which light is burned out on a string of Christmas tree lights when the whole string goes out just because of the one burned out one? This frustrates me every year.
I already know starting at one light and going thru everyone. Ughh. Just wondering if there was an easier way. We have a prestrung tree and some work and some don't. So I cannot really buy new ones as they are attached already.

Find It With a Tool:

Take a look at this site:

http://www.ciphersbyritter.com/RADELECT/LITES/XMSLITES.HTM

It recommends a tool for this purpose called light keeper pro, which sells for $35 (for one) but many places instead sell 8 of them together for $180 -$240 (higher due to season at some places).

This tool may even fix the problem while highlighting the problem, and even when it doesn't, it has a backup method to detect the 60 Hertz line voltage hum on connected (but partially dead) Christmas lights, to find where the dead light bulb is (look at the pictures and the description on the site I mentioned above).

This tool can also find loose bulbs, which is apparently quite common.

You could use this tool many years, even help your neighbors/relatives.

Note: If you may convert to cool-to-touch low-power LED lights in the next year or so, know that this Christmas light tester tool does not work with LED lights, according to the author of the web page above (he also has a page for LED Christmas lights; follow the link on top of his page).

Find It Yourself:

Now, maybe you don't want to buy such a tool just for this purpose. What's the best way to find the problem bulb?

First, push all the bulbs in a little to make sure none of them is loose. The lights still don't work? A bulb has probably burned out...

Well, where there is fire, there is smoke...

Often, a burnt light bulb will look darker. The burnt filament may leave a charred dark spot inside the light bulb. It may even make the whole bulb much darker.

If you are asking "what's a filament?", look at the images of incandescent light bulb, and Christmas light bulb:

Its filament will be broken, and even a loose piece may be in the bulb. I think a cheap and easy way to try to find the broken Christmas light is just to look carefully.

1. Prepare:
+ Unplug the Christmas lights!!
+ Get a small clean white piece of paper (preferably bright white, without lines on it)
+ Get a magnifying glass if you can
+ Use an evenly distributed bright light source
(flashlights that display patterns could be confusing)

It's better to wrap up the lights and take them indoors, keeping bulbs closer to each other to see darker bulbs more easily. If this would be hard to do, just examine them in place, but make sure you have enough light.

2. Look:
+ Start with the darkest looking bulbs or just go through the light string.
+ Turn each Christmas light bulb upside down if possible (so its tip looks down)
+ Hold the piece of white paper behind each light bulb
+ Examine the light bulb closely

3. Find:
+ If the filament is broken, this bulb is dead.

Other things may also happen when a bulb burns out, and these are easier to see.

+ Does the light bulb look darker than usual?
+ Is there a loose piece of filament floating around in the bulb as you rotate the bulb?
+ At this angle, a broken filament may be dangling towards the bulb tip.

If you notice any of these, examine the filament closely. Quite probably, the bulb has burned out.

Also, if the bulb is broken, or even if it is cracked, just replace it even if the filament looks good; bulbs should not have any air inside them. Oxygen + hot filament would cause fire (hopefully a tiny one that touches nothing).

4. Fix (Replace) and Test:

+ Replace the bulb.
+ Test by plugging in.

5. Continue:
If lights don't come on:
+ Unplug the lights again!
+ Continue testing (back to 2)...

Good luck!

At the beginning of the 1980’s in the United States Professor Rosenthal discovered the benefits of light therapy lamps.  At first they were used in cases of seasonal depression also called SAD (Seasonal Affective Disorder).  Light therapy is today practised in a number of hospitals a number of pathologies, but mostly with trouble linked to the upset of the biological clock (circadian rhythm problems) like insomnia and generally trouble sleeping.

Light therapy reveals its effectiveness in numerous cases, and helps to quickly find energy when a lower morale lets us feel the changes in the seasons.

Light therapy lamps and seasonal depression or SAD.  The principal symptoms of winter season depression start to show at the end of summer when the days start to grow short and become dull as there is less light it is the seasonal change that affects a number of people.

In a number of cases it is Winter Blues which we all suffer from in one way or another, it is a simpler version of winter depression, and this in no way stops us from continuing with our daily lives.

In the cases of SAD people will suffer from a depressive state, tiredness and will have a tendancy to isolate themselves socially.  Also noticing a significant rise in their appetite with a tendancy to gain weight or even bulemia due to sweet foods, gloomy humour a tendancy of insomnia and an excessive need of sleep, loss of concentration and motivation with a loss of interest and a loss of out put.  The people suffering from seasonal depression do not automatically show symptoms, this is why it is important to contact a doctor for a check up.  The signs of this depression disappear with the arrival of beautiful days and sunlight.

Light therapy lamps : How does it work?

Light therapy consists of facing a light therapy lamp which transmits light to the eyes. The intensity of the light should be between 2500 and 10 000 lux (light units).  It is the retina via the neurotransmittors that inhibit the melatonin, a sleep hormone which is at the root of the problems linked to a loss of light.  This homone is normally secreted at night for us to sleep. The fact that this sleeping drug is naturally blocked during the day helps us to find out natural energy.

How to use the light therapy lamps

First you have to remember that light therapy lamps used as treatment in hospitals and at home respond in the same way as any normal medecine.  This is why you should verify that the lamps have an agreed EU license.

The origin of light therapy lamps are reserved for medical use (by a GP or at the hospital).  Today light therapy lamps may be used at home, at the office in response to normal usage.

The power will be the first factor in the choice of a lamp, of course the more powerful the lamp the more the use will be a greater comfort.

Each session should be done in the morning.  The user must place the lamp at eye height or just underneath the eyes.  It is not necessary to look at the lamp but it is important that the retina swims in the light coming from the light therapy.

The length of the session must be between 30 minutes and 2 hours (30 minutes at 10 000 lux or 2500 lux for 2 hours).

The effects on the morale can be felt quite quickly, from the first couple of days, but may take 10 days for others.

There are very little indications against light therapy but it is important to consult a doctor when the person suffers with their eyes or is taking photosensitive medication.
