Best solar light, UV LED to use for UV Sun Jar Answered
I'm making a Sun Jar, but I want to swap out the normal white LED for a UV LED.
My plan is to spray the inside of the jar with invisible UV reactive paint, so when then LED comes out, the jar suddenly starts glowing a different color.
I tried making one tonight, but wasn't happy with the results. I was using the black plastic Hampton Bay light from Home Depot - http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&productId=100068888&langId=-1&catalogId=10053&ci_sku=100068888&ci_src=14110944&cm_mmc=shopping-_-googlebase-_-D27X-_-100068888&locStoreNum=1002&marketID=48. It's only powered by 1 AA battery, and the resulting glow from the LED was really dim. I got no reaction at all from the UV reactive ground marking paint I was using in my test.
