Although I severely dislike LED retrofits, I do think if there was a way to block the appearance of each LED this would look more like LPS and would be considered OK just by a hair in my books lol

You mean 400w bulb on 250w ballast? That'd give you the LPS colors the bridge was originally lit with.

If I were to keep the original light. I'd use amber LEDs. For higher CRI I'll use that soft white LEDs.

Why I like LEDs on top of other lighting tech?
LEDs = Upgrade 95% of the applications. (That is if you avoid eBay's LEDs).


LED brainwash? No, people uses them cuz they work well for them.

I guess they replaced the ligthing due to unclear future availability of SOX lamps for relamping, and possibly wish for higher CRI

As i understand it, they wanted to save the overall appearance of the bridge in day and night. IMO this means, replace Amber only with Amber, Orange or other closely matched color. Definitely not with white of any sort, not even warm white

If they do want higher CRI, HPS is a perfect solution

Amber LEDs can come out great, but will depend on how it is done - Hide the individual dots, use proper optics (no lens arrays) and so on. For one, Amber LEDs can be used to provide narrow peak spectrum with CRI still close to 0, so more similar to the original lighting than HPS, If that is the desired effect

The bridge was originally LPS; it was converted to HPS in 1982 due to the original system aging but they saved one of them off the bridge by the visitors center in my other photo, the new HPS shoeboxes with the yellow lens don't, IMHO, look bad, but I don't really like the warm white LED retrofit.
