Replacing 40W Spot Bulbs with 6W LED Spots

I’ll do a couple of quick posts to share how I have improved efficiency in situations/fixtures that require non-standard or hard-to find bulbs.

40W Spot bulbs

The 40 W spot bulbs are used in recessed and small table lamps. With my adapter + bulb contraption, the spot light even looks nice (IMO)These are hard to find in CFL because of their small size. I couldn’t find a direct replacement that had enough lumens to be any good or had a good temperature.

What I did is I bought some LED GU10 bulbs that are smaller. The GU10 plug looks like two fatty prongs that are intended to be twist-locked in place (see the pictures). I then got a ceramic adapter that has a normal bulb screw on one end, and a socket for GU10 plug on the other.

Despite this looking weirdly "long", the overall length and diameter is exactly the same as those stubby 40 spot lights.With that, I could adapt some EcoSmart bulbs and they worked great. Here they are in HomeDepot but with a different packaging than I had them (I bought them in little cardboard boxes, and Amazon doesn’t carry them as I write this). I wish I hadn’t given away the old normal bulb to give you a comparison image – when assembled, the picture of the combined bulb+adapter to the right looks disproportionately long, but the overall length is less than a 1/8th of an inch longer than the original.

 The adapters are not cheap (I got them at Amazon for $5.95) but worth it. These lamps tend to spend a couple of hours on in the winter. I got rid of 2 bulbs, so 2 x 40W= 80 W went out and got replaced it with 2 x 6 W = 12W. It repays itself in 5 years with calculated guesstimates.

Finding a bulb that I liked wasn’t that easy – the Philips brand was both too bluish,weak and had a weird, diffuse shadow. These are brighter but 3000K. I would have preferred 2700K for a mellower, warmer look. Still these look great and given how much they are used definitively worth it.
