You might have seen these solar spots, with 3 small led's. I see 3 areas of fog where the light shines through. The rest of the front plastic is clear. They are not warm led's. A noticable bluish cast. I bought about 7 of these, I use around the yard and camping. The ones I have not used much don't have fogging.
Harbor Freight and others still sell thm, but not as good quality.
