Need LED Bulb

I am trying to find the "shortest" led bulb I can find in about the equivalent of 75 watts.

It can't be more than about 4 inches high as I'm putting it into an Automatic Light Control and the whole thing has to fit in a standard porch light fixture.

Had to buy regular 40 watt bulbs so they would fit but they aren't showing enough light at night. Also want to save some energy with the led type.

Have looked all over and think maybe they just don't make them like that?

I like the CREE leds. Spec says 4.4 inches, but I've found them to fit everywhere a standard bulb will fit. https://www.1000bulbs.com/product/11...FVaRHwod3gAOXw

I second that. The Cree lamps are great, and look almost exactly like incandescent, and have very even light distribution.

Thanks, I checked their site earlier. Not sure if 4.4 inches will work. I will have to take the top off the fixture and get a more accurate measurement.

I know I could just replace the entire fixture but IF I can find a bulb that fits it (into the light controller) then I'd be all set.

The light is already on a separate switch so it would be very simple to just leave it on all the time and have the bulb go on and off of it's own accord.

Hi Smokyie,
Not sure where you are measuring the 4", just the bulb or the bulb plus the base.
As for brightness, I use daylight in the 5,000K range and they give me much more light than the cool light at 3,000.
There are also some short neck led flood lights. just looked at one and it was 3.75". Not sure how wide a beam you need.

Thanks for replying. My standard type bulbs are about 4.5 inches (total) and I can get the top on the fixture but it's just too tight to screw it down. So if I could find a LED bulb about a quarter inch shorter it might work.

Don't think a flood light would work as this is for a porch light fixture.

Thanks.

The Phillips Slim Style looks like a small tennis racket, but it is plastic with a ridge around the outside. It starts at 4 3/8th and I'll let you judge if any of that plastic could be removed. Sure looks like it, bulb in hand. The one I have is 60 watt @ 5,000K. They are calling it cool as opposed to warm, but I call it daylight, a white light vs yellow. I believe they had a 75W eq as well, a bit more money. These were about $5.

The desired dimension is getting close and even if it doesn't work, you can use it elsewhere.

Found some Sylvania CFL's - called "Micro-Mini" so got those in. These are 900 lumens (60 watt replacements) but they also have a 100 watt replacement if these aren't bright enough. Will know tonight.

Thanks so much for trying to help me with this.

Now, I read the box and it says to not use with photo cells - so does that mean they will just burn out faster?

Just wait until your cold weather sets in. You will get more light out of a kitchen match than the CFL when it is cold. One to five minutes before you get usable light.
If you were to go with the Cree 60 watt, it is only 4" tall.

4.4 inches for the Cree 60 watt - just a little too high. Might just go back to the shorter 40 watts but know they will use more electricity and aren't really bright enough.

Are you using one of the screw in photo-eyes and that's why you can't fit a normal bulb? Consider using one of the wire-in photo-eyes instead; it wouldn't add any height.

Yes, and one of them is maybe half an inch higher than the other one. Have two light fixtures. However, the CFLS I put in today seem to be doing a good job so far.

Thanks for replying.
