what is the critical thing to be cared about making a lighting fixture in cold freezer warehouse?

THE FIXTURES YOU ARE USING WILL WORK PEFECTLY!\ncreate a small cubby room and call it the lighting closet.\nhouse your ballasts in this room at 75-80 degrees\nballasts and lights are seperate making startup easy and troublshooting problems easier.\nextra wiring involved but very profitable in the long term\nblow a ballast?\ngo to the comfort of the lighting closet and change it!\nyour fixtures dont care about temperature\nyour ballast needs warmth to operate correctly

It will be fine, just move it to a cool dry dark place like a cabinet.

somewhere around room temp\n\nin a freezer

Under Health and Safety regulations, your environment must be kept at a 'reasonable' temperature.  There is no fixed temperature although there are guidlines.  The reason that there are only guidelines is because someone who is moving around, shifting heavy items is going to require a cooler temperature than someone who is sitting at a computer.  If a number of people find it too cold and you complain, then by LAW something has to be done about it.  If the temps are low due to a short term failure in the heating system, then you may be expected to try and cope for a short period of time.  So in some circumstances YES, you do have the right to walk out, but make sure you have objected first, dont just jump up and say - hey, I'm outta here

Safety, colour, energy efficiency, use of the space, luminosity, age of room users, dimming and mood, position of bulbs, light shades.\n\nFluorescents are more energy efficient than incandescents (20% compared to 5%) so they are cheaper.\n\nAreas for close up work should be lit more brightly. Intensity decreases according to distance from bulb^2 so intensity 2 m from a bulb is 1/4 of intensity at 1m.\n\nOlder people need more light. A 50 year old needs four times as much light as a 10yr old for the same task (This is why children can read by torchlight under the bed.) Make sure the occupant of a desk does not shadow their light source.\n\nIncandescent bulbs have more red -yellow in their emission spectrum, fluorescents vary but white ones are similar to daylight. Note: the apparent colours of furnishings can change dramatically with a slightly different colour bulb.\n\nFeature lighting can be used to highlight objects eg plants, books, artworks on a shelf, hidden strip lights (eg under pelmets) soften the strip light.\n\nIn many settings, several wall mounted lights create a better atmosphere than a single central light.\n\nCheck that light shades don't colour the light or cast annoying / weird shadows around the room. This is more likely if the light is the only source in the room

The short answer, is worker comfort and machine operation.  Semiconductors are assembled in "clean rooms" where personnel must wear special clothes to prevent dust from collecting on sensitive equipment.  It has been said that most of the dust in a house is often dead skin, etc.\n\nSensitive equipment must be manufactured to very close tolerances which could be exceeded with uncontrolled temperature and humidity changes, thus ruining expensive product.  Therefore, buyers and sellers of equipment must agree on specified conditions such that if equipment performs to spec at the factory it will perform satisfactorily at the semiconductor assembly plant.  Air conditioning can be used to maintain steady clean conditions at spec temperature and humidity.  Remember that too little humidity may promote static electricity that can damage semiconductors and too much humidity can promote corrosion and the growth of molds.  Too high a temperature may prevent equipment from losing  heat generated during production and too low a temperature may promote condensation, especially from body perspiration.  Hope that helps.

A "fridge" in the sense you are speaking isn't realistic. If you really want something that cold, get some liquid nitrogen and go nuts.  It's not as cold as, say, liquid helium... but oxygen in the air will nicely dissolve into liquid nitrogen, and you don't have to keep it under any pressure.  If you want to create a fridge, the best way would be to create a vacuum on the inside and line it with copper (silver plated, ideally) pipes all over the place (for conduction). Cycle the liquid nitrogen through a compressor and through the pipes. But why? This would likely cost 3 or 4 grand to get something that actually works.

It would melt the ice above it, which would drip on the candle and put it out. Of course, if you had an entirely frost-free freezer, then it would continue to burn until it uses up all the oxygen as has been suggested. Freezers don't get nearly cold enough to prevent combustion from taking place, if that's what you were wondering.

here is a link which I hope will help. http://www.hgtv.com/hgtv/dc_lighting_other/article/0,1793,HGTV_3466_1372885,00.html \n\nyou may have to adapt the info to the flower pots you want to use.  it has clear pictures to illustrate the process.   have fun!

Lighted garland from railing.  Icicle lights from ceiling.  C-9 multi-colored bulbs on everything else.  A couple of inflate-able figures.  A good timer with multiple outlets will keep the bills lower.

Throw light . \nwhy, doesn't the place get any sunlight.

An ice house..., covered in saw dust lasts all summer..., same with snow..., tree planters cover their trees in winter with snow then saw dust..., snow will last right til August / September...., so just put your cube in there...\n\nthere are many poor conductors for heat..., what I would do is wrap the cube in tin foil..., then wrap in white plastic (some people refer this as a cooler) or white foam..., etc....

You have to turn one light on for a while so that it'll warm up, turn it off and then turn another light on. then you can go into the room and feel the two unlit bulbs - whichever one is warm is the first one. The lit bulb is the second and the cold bulb is the third\n\n=)

Call your supplier and ask.  Though I doubt it is anywhere near as cold as it gets where you are otherwise it is not what people would use to heat their homes.

There are a number of products on the market that will do what you want, and be certified and safe.\n\nMake sure you get a warm LED though: cool white LEDs produce a terrible colour of light.\n\nhttp://www.theledlight.com/120-VAC-LEDbulbs.html

you should rethink the program, maybe you missed something in the blueprint that would help you, Also maybe the program is wrong. Also have you made sure that the fixture you are using is correct...Also it could be the inserts you are using..Try a colbalt...That is what we use.
