content: Hi,I've been searching over the internet for bar graphs with red tinted lenses, such as the attached photo, I eventually found one from the brand "sharp" (the photo comes from one of those), but it's almost impossible to find them at all to purchase.Has anyone ever come across other bar graphs such as these ? The only ones I could find otherwise had a white lens for the LEDs, but I'm specifically looking for ones with a red lens.Thanks.

content: Easy enough, take the one you have a make some more. The LEDs are readily available.It's hard to find exact copies of the ones you have as they were common during the 80s and 90s on audio equipment but they all differ ever so slightly. You might be able to buy some from the vintage audiophiles or you could buy some but of kit with dual sets of these and take it apart.

content: These any good?https://sunledusa.com/productSeries.aspx?ser=XHxxX12DWBMight be worth dropping them a line for samples or stock info, they are listed on Digikey but Out of Stock.https://www.digikey.co.uk/en/products/detail/sunled/XHURX12DWB/4902297

content: Quote from: jc101 on January 02, 2023, 02:32:03 pmThanks for your reply,these are the correct kind, but they need to be tinted red (like in my original post's photo). I can't tell if they are as I couldn't find pictures of specifically the red one, I know it probably sounds silly because I could probably just take white ones and find a way to tint them red, but I need these for a reproduction project, and I'm trying to look for any brands that did these kind of bar graphs tinted red, as I would prefer to have original/matching electronics.

content: QuoteTheatre filter/gel,available in multiple shades of red.Lee and rosco are the 2 main brands and do swatch book containing samples of all there colours.

content: Quote from: Roberto89 on January 02, 2023, 09:58:54 pmSunLED's product description states "Lens: white diffused", so I am pretty sure they are not red. I am afraid you will have to paint them red yourself, with a suitable translucent red lacquer.Nail polish has worked well for me in a similar application: Comes in some nice deep red translucent/transparent tints, has a good consistency, and comes with a handy little brush. And you will get some interested looks as you study the nail polish shelves.The LEDs on the photo in your original post look like they have a textured surface too -- is that important to you? That would complicate things...

content: Quote from: ebastler on January 03, 2023, 08:04:00 pmI like the nail polish idea, if I can't find any other alternative, I'm definitely going to try this.For the texture, right now I'm not certain if it really matters, the issue is, as I've said I'm gonna use these bar graphs for a reproduction project, but the photos I'm using as a base/reference aren't good enough to distinguish whether or not it had this texture as well, and I have no idea what kind of brand they had for their bar graphs (it's also partly why I wonder if any other identical bar graphs exist from other brands, or existed... Because if theoretically, no other brands did those in red, then it'd mean for sure that it had this texture).What I know for sure though is I can distinguish it was an actual "molded in one" bar graph, and not individual squared leds set in array inserted in a bezel.

content: Quote from: themadhippy on January 02, 2023, 10:47:36 pmI already have a red filter/gel to color lights, I think it's similar to what you were referring. I'm not sure how easy it would be to perfectly cut it to make it fit, but I thought about doing such a thing, if I have no other solution/alternative...
