Purchsed mine off Amazon, best price anywhere, no problems. Easy to install. Just be careful handling the board and taking off the old one. There is a ribbon the connects to it.

I do not remember buying one from Amazon. What I know is that I bought one most likely from the local Sears. However, what I am reading online is that the -1 model does not support any light. I hope this helps.

The one button replacement worked for my garage door. I don't have a lock on my garage door. I don't know what the other 2 buttons are for and thought it might be for a lock or light.

Not sure? But after programming my new opener my old one still works . I find I have to click 2 or 3 times to open

Well, Patty, we actually bought a LiftMaster Security + (http://www.amazon.com/Sears-Craftsman-139-53681-Remote-Equivalent/dp/B00283W5LO) THe circuit board inside is a light green -- my wife says moss green. It worked fine -- but you've got to follow the manual instructions on synchronizing the code. After a couple years, we did end up replacing the entire opener with a different brand. I have the Craftsman openers -- not sure why we kept them. Cover my mailing costs and I'll send them to you. arboldt@bigfoot.com

I'm thinking that the 2700K and the 3500K is the lighting level of the bulb in Lumens. The 3500K is a brighter light than the 2700K. You might Google "Lumens." I'm thinking that it shouldn't make much difference in the operation of the bulb as to generating heat, but not sure of this. I put in a brighter bulb in my house and haven't had any problems with it. I put in the larger number because that was the only one available. Incidentally, heat will degenerate the fixture if it is made of plastic so stick with the 55watts if you can.

I think that was the number for the gear on my opener. Hey, it's Amazon. If it doesn't fit, return it!!

You can find the compatibility list for part No. 41AC050-1 at http://www.usdoorcontrol.com/item-618.htmlI hope this is helpful.

I think this product has been redesigned since the model you have. If your product has a light it's the earlier model. They redesigned and cheapened it but retained the same model number. Unethical? Amazon should remove all reviews from before the unit was redesigned.

I believe my original keypad was 25 yrs old (installed same time as the opener). I was only lucky to find this exact replacement on the internet. I would have been uncertain about purchasing a different model.

I have both the replacement lamp from Amazon and the OEM installed...one on either side. I see no difference in the brightness or light. It was a good match for me.

I'm not positive, but one is most likely low beam ad the other high beam. If you have separate bulbs for hi lo, other one might be standard just lo, and the other might do hi and lo, I got the 10k single beam and have never needed to use my factory brights cuz they are about half as bright. Hope it helps

I think you need to check the model number of the carrier again. 59516 is the light kit model number

I purchased the Model 8500 which shows the 475LM as an option. I looked up your Model 2580 instructions online and didn't see the 475LM as an option for your opener. I would call the manufacturer just to be sure though.

Hey Sandie, It won't work with that make of operator. If you let me know the color of your programing button on your opener I can have a solution for you. Thanks... Matty

You would think it would just run off the power going to the opener. I assume its for the light that lights up the buttons when you open it up.
