Ok, sorry for the carpet-bomb of pictures, but I tried to get every combination I could think of... I'm no photographer (I like the 'auto' button on my camera, all the other numbers scare me!) but I set the camera to a fixed setting, stuck it on a tripod, and tried not to move anything between shots. So hopefully this is a good comparison. I've never actually compared the white EL to the stock one side-by-side, so even I was actually impressed. Overall, it's brighter than the stock orange EL sheet, and about as bright as the same stock EL sheet after you scrape off the orange to make it blue. They're identical in size, except I added a tiny bit more EL to the right of the 'idiot light' area. It has essentially no effect, I added it when there was talk about extending the speedometer past '160' down into that area, and a little extra would have helped light up the extra numbers.
Here goes! I'm going to just post all the pictures, then edit the post to add descriptions. So you may see text pop up here and there if you're seeing this while I'm editing it.... (Or since it's 11pm, I might edit tomorrow..) By any means, if you want to see a combo that I missed, ask and I'll try. (Assuming I have the means to do it - I only had white LED rings left, and pretty much only have a couple sets of Harley needles)
1: 2 '2005' instrument clusters, stock faceplates, Harley Davidson 31mm needles, with white LED rings. They're both connected to the same power supply, set to 13.6v, headlight wire "on". (car will range from 13.3-14.4 I think?) Top panel has stock orange EL sheet, bottom panel has new white EL sheet.
2: Lit up with stock faceplates. Top = stock orange EL, bottom = white EL.
3: Not sure why I included this one, see 4.. LOL
4: This probably should have been #1.. Top = stock orange EL, bottom = white EL. It appears pink when turned off, because (I think) they make white by coating a blue sheet with a fluorescent coating, similar to how they make white LED's. The blue excites the coating, making white light. The only place I can see the tiniest bit of pink is under the "Lotus" logo in the center of the black faceplates. **But, the original / first revision aftermarket faceplates had the logo hole a bit too high, so the top of the circle doesn't fully light up..
5: Comparison of the stock orange EL and the white EL, both naked. I forgot to re-zero the needles on the bottom cluster.. You can see the numbers from the stock faceplate burned into the stock EL sheet from sunlight!
6: Stock orange EL on top, behind a black faceplate, white EL on bottom below a black faceplate. There is the slightest bit of a bluish tinge to the white EL; it's not BLUE by any means, but it's not as white as sunlight, halogen light, white LED light, etc.. It definitely looks white lighting up the numbers on a faceplate, but just don't want to give anyone incorrect info. Especially these days with the super-bright illumination in newer cars.
7: Setup for next picture - still stock orange EL on top, white EL on bottom. Just with a red faceplate with no Lotus logo. This is the one I usually have in my car, which is why I went with white needles instead of red. Red needles on red background = "I can't see how fast I'm going!" in the daytime... LOL
8: Above setup lit up. Again, orange on top, white on bottom.
9: Not really sure why I took this one.. It's really the setup for #11, white EL on top, scraped stock orange panel on bottom to make blue.
10: Stock orange EL on top, scraped orange EL on the bottom. If you scrape too deep, you get a dark patch........
11: White EL on top, scraped orange on the bottom. These are about the same brightness, at least to my eye when I was looking at them. The white looks brighter in the picture though. "The camera doesn't lie?" LOL
12: Black faceplates, top is white EL, bottom is scraped orange EL.
13: Another extra.. Same setup - white EL on top, but with red faceplate, scraped orange on bottom with black faceplate. I guess just showing that the red and black ones light up the same?
14: Hmm, getting repetitive.. (it's past my bedtime!) Black faceplates, white EL on top, scraped orange on bottom..
15: For another comparison.. OEM 'white' faceplates, white EL on top, scraped orange on the bottom..
16: Should be somewhat self-explanatory... Stock orange EL sheet on top, white EL sheet on bottom. Outer dimensions are the same, connector is the same, holes in same locations. I straightened out the 'bump' at the top because I didn't know if they could print it like that.. And as mentioned about 1/8" more material to the right of the 'idiot light' area on the speedometer side of things.
17: Back side of the panels... You can see how the conductors go around the whole panel for even distribution of power. When I cut up a 'universal' rectangle into this shape, I lost most of the conductor around the edges and it lit up patchy..
18: Last, and, well, maybe not least to some people? Comparison of size - stock on top, white on bottom. You can clearly see the extra bit on the right..
That about wraps it up for now! I'm getting some sleep.. If anyone isn't on high-speed internet, I apologize for melting your internet connection!
I'll get back in touch with the EL company and make sure they're still on board with making them at the same cost they quoted me before.
