The "T" number indicates the number of 1/8th of an inch in diameter. A T7 would be 7/8" diameter, and T8 would be 8/8 or one inch in diameter. But from what I can tell, the length of the bulb is the big factor most people run into. Most incandescent T8 bulbs I find are 2.5 inches tall over all, and T7 bulbs appear to be 2.25-ish.
Try it and see Having a T7& T8 like I have prevents me from walking without the aide of a walker. Had the injury been lower there would have been a chance for me to walk without a device. Spinal Cord Injury is not a one size fits all. Perhaps there is someone out there with a T7 & T8 who is waling without a devise. Usually the T7 & T8 causes a weakness in your truck area..lose of control over your bodily functions..weaken abs. Exercise is key to your recovery and health. Anything is possible..believe in your ability to make it happen!

t8 68% of people have their lower (inferior) angle of the scapula at the level of T7-T9. So the mid point of this is naturally T8 but there is some variation.
In a T* ballast and T8 bulb more energy efficient then a T12 ballast and a T8 bulb? A:Depends on the CURRENT through the tube. When the Tube is run at 100% of rating, The T12 Takes more CURRENT to give a certain Brightness. Because the surface of the T8 is closer to the ion stream through the tube, it takes less CURRENT to light up the T8 to the same brightness. However, IF you use a T12 in a T8 ballast, you will get LESS CURRENT through the tube, and LESS POWER consumed ALONG with LESS Light.
There are t1, t2, t3, t4, t5, t6, t7, t8, t9, t10, t15, and t20 sizes.
Yes a T12 lamp socket will take a T8 tube. The T8 tube will not operate. The T8 ballast is an electronic ballast where as the T12 ballast is a magnetic type. If you are changing over fluorescent fixtures to the smaller T8 lamps then the ballast has to be changed and the end sockets have to be rewired. The schematic on how to do the rewire is on the electronic ballast's label.
By far the hottest of the two light sources is the light bulb.
I had very similar symptoms at that location. An mri revealed it to be a tumor in my spinal column. Fortunately it was benign and was removed surgically. Suggest you get an MRI to determine the issue as soon as possible.
We will use the quotient rule here. express sqrt(2) as 2 1/2.d/dx[f(x)/g(x) = [g(X)f'(X) - f(x)g'(x)]/(g(x)2d/dx[t7 * (2 1/2)' - 2 1/2 * (t7)']/(t7)2= t7 * 0 - 2 1/2 * 7t6/t14return to sqrt(2)= 7sqrt(2)t6/t14============ cleaned up7sqrt(2)/t8========
Depends on how high it is off the floor. Make sure you buy a T8 and not a T12. The T8 puts out more light and will operate at a lower temperture. On a normal 8' ceiling a 2 bulb T8 will cover around 36 square feet of space. If the room is pretty large then an 8 foot 2 bulb HO light is a much better choice.
