My blue "Spire NeonBar II" Cold Cathode light went dim (not all the way out) all of a sudden only after a month 1/2 of use. Is there a better option to light up my clear side panel case? I've seen led lights but are they any good for lighting up a case? Before my current cathode I had a Ultra-branded cathode that probably lasted for more than a year until it got broke from sitting out. Any other options? What have you used that has lasted? Thanks.
