Electricity is NOT clean, meaning, it is not 208, 220, or even 240. It usually varies and spikes. The problem with the lights, is likely because it's cold in your shop. Florescent lights do not perform well in the cold. (or they might be getting old).
However, you can test your "average" voltage coming in with your vom (volt omm meter, set on the 240 volt setting).
However, the very existence of surge protectors should give you a clue about the consistency of electrical voltage.

208 volt equipment on 240 volts
The heater will operate over its given specified wattage. Equipment rated for 208 volts and operated on 240 volt will have an output increase. Ohms law stated that current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
For example if the heater is 5000 watts at 208 volts, the current is I =W/E 5000/208 = 24 amps. The resistance of the heater is R = W/I (squared) =5000/24 x 24 (576) = 8.68 ohms. Applying 240 volts on the same heater whose resistance is 8.68 ohms results in this new heater wattage rating. W = E (squared)/R = 240 x 240 (57600)/8.68 = 6636 watts. This is 1636 watts higher than the manufacturer's safety rating.
W = watts, I = amperage, R= resistance in ohms and E = voltage.

What is the maximum volts that can be used on a 208 230 volt motor?
You should not go above 240 volts for that type of motor.
Amp meter is showing 208 volts I need 240 volts?
There is some equipment that will operate on 208 volts even though it is rated to be use 240 volts.See discuss question below.
How many Amps for 3 horsepower at 208 volts?
For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.
I have a electrical dryer 240 receptacle that reads 208 on voltmeter and the dryer display reads Pwr Failure and will not operate were did the other 30 volts go?
I am assuming that you have just moved into a new apartment building. Commercial building power systems are changing to 3 phase. The 3 phase voltages are 120/208. 240 volt equipment will run on 208 voltages but at a reduced wattage output. For example Watts = amps x volts. Say your dryer draws 20 amps x 240 volts = 4800 watts. Now at reduced voltage, 20 amps x 208 volts = 4160 watts. As you can see your dryer won't get as hot and will take longer to dry. Most apartments that come with appliances will be rated at 208 volts. See what your dryer manufacturer has to say about getting around the Power failure alarm or whether it can be bypassed to operate on the lower voltage. Other option is to sell the 240 volt dryer and buy a 208 volt dryer. at 208 volts it will not draw 20 amps either
How do you wire a 4 wire 3 phase to make 110?
In North America the only three phase supply that 120 volts can be obtained from is a 208 volt system. 120/208 is a common voltage connection that is used in many apartment and commercial buildings. The 208 voltage can be used in lieu of 220 volt appliance equipment and the line to neutral voltage results in 120 volts. It is obtained by the following formula 208/1.73 = 120 volts. For apartment distribution panels, two of the three legs are used along with the common neutral. The main distribution is kept in reasonable balance by alternating different apartments on different legs of the three phase distribution service.
Does a 208 volt outlet need a neutral?
No a 208 volt outlet does not need a neutral. 208 volts is the line voltage between any two legs of a three phase 208 volt system.
Can you operate a 208 volt on 110 volt?
The United States is one of the only places in the world that uses 110 volts instead 220 volts. In order to operate 208 volts on a 110 volt electrical current, you will need a voltage converter.
What happens when 240 volt equipment is plugged into a 208 volt source?
It should be ok
What is the maximum volts that can be used on a 208 230 volt motor?
You should not go above 240 volts for that type of motor.
What is a 208 circuit?
The 208 volt configuration is one phase of a three phase source at 240 volts, where the 208 volt circuit is connected between the center tap of one 240 volt phase (usually a grounded neutral, in the style of a standard 120/240 split phase system) and the high delta connection on either of the other two phases. 208 circuit would consist of two phases of a 208 volt wye system or could be all three phases. The voltage between conductors would be 208 volts. The voltage to ground from any phase would be 120 volts. A 240 volt delta system would give you a high leg to ground, somewhere around 190 volts and the other two would be 120 volts to ground.

There is some equipment that will operate on 208 volts even though it is rated to be use 240 volts.See discuss question below.
Can a 230 volt supply be reduced down to 208 volts?
Yes it can be transformed from one voltage to the other.
How will a 3 phase panel give you 110 volts and 220 volts?
A three phase panel will not give you 110 and 220 volts. A three phase four wire panel will, but not at these voltages. The nearest voltages will be 120 and 208 volts. The 120 volt is the wye voltage of 208 volts. 208/1.73 = 120 volts. A single phase three wire panel will give you 110 and 220 volts.
How do you convert 230v to 208 volts single phase?
A source of 208 volts can be obtained from any two legs of a three phase four wire 208 volt system. The two legs are classed as single phase 208 volts. The lead tags can be L1-L2, L2-L3, or L3-L1 all of which will give you 208 volts. Any of these lead tags to the grounded star point (wye) will give you 120 volts.
How many Amps for 3 horsepower at 208 volts?

If you have a 3 phase and 120 volt per phase electrical source how would you connect a heater element requiring 208 volts?
Answer for USA, Canada and countries running a 60 Hertz supply service.It sounds like you have a three phase system to connect to. If it is 120 volts from phase leg to neutral then the three phase system is 120/208. To connect the heater to a 208 supply on the distribution panel connect the load across a two pole breaker. The amperage rating of the breaker will depend upon the wattage of the heater. Amps = Watts/208 volts.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
