LEDs going slightly over wattage

I just had someone install a new Harbor Breeze ceiling fan and I went to put in some LEDs that I had that were 800 lumens and 8.5W. The ones that came with the fan were 6.5W and 600 lumens. There was a warning not to exceed 6.5W.

So my question is can 2W really make a difference? Is that a fire hazard if I put in the 8.5W? What does the community think? Thanks

Are you certain the fan said 6.5 maximum or does it say 65 watts maximum? I am accustomed to seeing fixtures that have a 60 or 100 watt maximum but I've never seen anything specify a maximum as low as six and a half watts.

Yes I'm certain it was 6.5w since it says the lights are for LEDs

Then I would say that's the max you should use.

Additional 2 watts is a 33 percent increase. Do not exceed the manufacturers rating. Buy another fan/light that allows for higher wattage bulbs if that is what you want.

How many bulbs in that fixture?
Are the bulbs fully enclosed?
I agree with the skeptical thought that the max is 6.5W.
Unless there is something special about those lights the extra 2 watts is insignificant. However, forum guidance will not allow me to recommend exceeding mfg guidance.

Check their web site and/or contact them to get their advice.

6.5w is not much, I'd be looking for a different fixture,

If the device is UL approved, any change that increases power is significant because it has not been tested. If not UL approved and you want to experiment, make sure you understand you homeowners policy. You may need to use it.

Yea, I find it hard to believe that fan manufacturers are retooling and changing their design to only accept a light bulb at 6.5 watt ratting. LED's already use very little power and produce a lot less heat that an incandescent bulb. However, they do produce heat and should be vented to outside air. If in fact the fixture is rated for only 6.5 watts then the design factors are very close and I would not use anything higher.

A guess here. I suspect the fixture was an import and strange labels are to be expected as the translation often get as little care as the making of the products. IMO, the light will handle much more than the 6.5 watts that is reported. If the fixture went through UL the testing people would have covered a wider range as they too would know that is ridiculous.

The op simply needs to make some calls and send some emails and, again my opinion, clear this confusion up.

For the record my employer sent many products off for UL approval and they were always accompanied by an engineer to discuss the application.

thanks everyone for responding. I have to call the manufacturer monday. There are stickers on where you put the bulb that do say 6.5W max. HOWEVER in the manual it says use replacement bulbs no more than 60w max and it says use incandescent, cfl or LED.

To answer another question it is not enclosed the fixture. LEDs produce such little heat its hard to imagine 2 W doing anything. Maybe the sticker is wrong?

Is there a "made in (?)" sticker there? Sounds like the 60w is correct, let us know.

I'm betting the 6.5 watt is a mis-print.

I called the company harbor breeze. They have no idea. Basically said I don't know why the sticker would be so different from the manual. A supervisor also said they didnt know.

Why am I not surprised? You might be able to dig through the UL.COM link and find the test specifications, I looks and chickened out.

Make some notes about what you asked and what they said, names if you got any and save it. A reasonable assumption is the 6.5W label is a mistake. I know the super cautious approach would be to believe it but that is contrary to the experience everyone here should have.

You could also contact the place where you purchased it and ask for clarification.

Also keep that manual.

What is the Lowes item number?

I can guarantee the fan is Made in China, I haven't seen a new ceiling fan in the last 10 years that wasn't made in China. I also suspect that the true rating is 60 watts per socket maximum.
