What is this bulb used for?
This is a replacement 36W tube for the Maplin full-size SAD light (A20HW). It boasts an impressive 8,000 hour lamp life and offers a 10,000 lux fluorescent light that is designed to help combat the symptoms of SAD.

What is Seasonal Affective Disorder (SAD)?
Seasonal affective disorder (SAD) or ‘winter depression’ is linked to reduced exposure to sunlight, which may affect your production of melatonin, serotonin and disrupt your body’s functions and patterns. Melatonin is a hormone that makes you feel sleepy, and serotonin is a hormone that affects your mood, appetite and sleep. Lower serotonin levels are linked to feelings of depression. Your body also uses sunlight to time various important functions, such as waking up, so the lower light levels during winter may disrupt your body clock and lead to symptoms of SAD and general fatigue.

How can the light help combat the effects of SAD?
Using a SAD light for a few hours at a range of 15cm away will help increase your levels of serotonin and decrease your levels of melatonin, this in turn will brighten your mood and make you feel more awake – giving you more energy.

please could you tell me the exact length and width of these tubes

I am sorry but as this is a specific replacement part for a specific item, therefore we are not supplied with any in-depth specifications as the item is not intended to be used in any other purpose.
