Lightbulbs in office


I have an office with 4 in wall canned lights in the ceiling. they are arranged in a 2x2 grid located in the center of the room. There is a fan located in the center of the room, attached to the ceiling of course. The problem is, the lights (I think) get too hot, and emit too much heat for this room. What wattage light bulbs would be best to change to so that the room does not get so hot?

That's tough to answer. Lower wattage equals less heat. CFL and LED bulbs emit less heat.

Or, you could replace the switch with a dimmer.

Well, having no idea what lamps you are using now, there is absolutely NO way to advise you what you wattage options are.

I agree with Seattle, have a dimmer installed.

Go with LED replacements. No heat, and will last longer. As for the dimmer, I would check to make sure that the dimmer you get is compatible with CFL & LED bulbs, same for the bulbs are compatible with dimmer switches. Also if you have a iPhone on Android, there are apps, that use the camera as a light meter, and you can check the LUM of the room. Too bright, you start having headaches, too dim, you start getting eye strain.

There is still a fair amount of heat, even with LED "bulbs". But, not as much as incandescent.

Is your heating & cooling system tied into your office?

So I have attached a photo of the description of the lightbulbs. Should I switch to lower wattage or lower lumens?


Please see attachment!

Oh, the 620 in the lower left is the lumen number.

Incorrect. CFL's and LED's do not give off any heat. The heat they do cgive off, is due to the rectifier circuit in the base, and it is minimal.

Lightbulbs in office


Thank you for the great feedback, but here are my questions.

1. Do I need to reduce the wattage of these lightbulbs? What wattage would be best?
2. Where is the best place to buy LED lightbulbs? Where is the cheapest place that I can buy LED lightbulbs for my office? What is the best brand of LED Lightbulbs?
3. How long do LED lightbulbs last?
4. Will I really need a dimmer if I put these LED lightbulbs in? Should I either put in a dimmer, or put in the LEDs?

Thank you so much!

Again, it is the rectifier inside the ceramic base, not the bulb. All a CFL is, is a whole fluorescent fixture miniaturized into a compact unit.

Do not know where you are getting that CFL's give off as much heat as incandescent bulbs, but both you and Seattle2k are way off base on this one.

LED's will last longer than the fixture will last. Average lifespan is over 25,000 hours for the low end bulbs, 50,000 to 100,000 for the more expensive units.
