I think you got the wrong category...try home improvement...

The range 50 to 80 degrees is above room temperature, so you need an electric heater and a power supply.  For small lab samples, a surface mount resistor is a good choice.  If precise control is needed, mount a thermocouple as close to the sample as possible and run the output to an A/D converter linked to a computer.  A very simple computer, or micro controller will do.  I used the original Apple for the job 20 years ago.  The computer should switch the heater on at a frequency proportional to the difference between the target and actual temperature.  This will give a damped settling to the target temperature and stability to better than 0.5 C.  For better stability, include the temperature derivative in your model.

something really harsh like paint stripper would have an effect as its quie volatile. if you can pour a flammable liquid into the tube such as petrol etc this will light from a distance but be super careful

You can download the Safety, Health and Welfare at Work Act 2005 from the first site below.  The National Irish Safety Organisation in a FAQ on Workplace Conditions answers the following question regarding the above act:\n\nIs there a maximum temperature for an office?\n\n"There is no maximum temperature stated under the regulations but as a guideline a minimum comfortable working temperature for indoor sedentary workers is 17.5 degrees centigrade and upper level for comfort is 27 degrees centigrade (when undertaking light duties)."

A person needs more info. What is ambient temp for design. What is the wall, floor and ceiling construction, insulation thickness and type. \n\nThese will determine the minimum design load, from that the condensor and evaporator coils can be sized. \n\nYou need an HVAC engineer or tech to do this.

The rule of thumb for tungsten filament resistance as a function of temperature is R = R20*(1 + 0.0045*(T-20)), where R20 is resistance at 20C (room temp) and T is temperature in deg C (ref. 1).  Operating temperature of incandescent bulb filaments ranges from 2500C to 3000C (ref. 2). So expect a 12- to 14-fold resistance increase from room temperature to operating temperature.

Zero. They won't do it. Engineers are too busy to change light bulbs and it's beneath them. Just one and he/she will tell you.

At work we just got motion sensitive switches.  If there isn't any movement for so long, the lights turn themselves off.  Saves a bunch on electricity.  Of course they automatically turn themselves back on when we walk through.

Yourself, taking time to turn off lights that are not being used and turning down the thermostat and wearing warmer clothing.Then insulation and florencent light bulbs that use a fraction of the energy over regular bulbs.

with the aid of a ballast which controls current to each side of the bulb and the bulb is filled with a luminescent gas that when heated will illuminate

check our pcdj.com they have a new lighting program for pc control with full dmx protocol\n\nits called " DMX"\n\nyou can program the lights to go with certain songs...etc,  its amazing!

I would think that for atmosphere Dark (like Theatres) is best.\n\nI hate watching TV in bright light anyway..\n\nPersonally I prefer to watch with a Table Lamp on in background or subdued light as is easier on the eyes....Cheers...
