Hello to all,

mercury vapour in any form for all :D. Second place is LPS. I love the real pink colour during warmin-up 8).

It has to be LPS, but than living in the UK, I grew up with that kind of lighting, which of course is now starting to disapear. Which is unfortunate in my opinion.   

Mercury Vapour (coloured or coated) would also come a close second. I would prefer to see that in extensive use as opposed to Metal Halide lamps.

My favorite bulbs are Christmas C7 with Candelabra Edison Screw (E12) with all kinds of colors.  I have few boxes full of C7's.
I also like Philips Halogena clear BT15 bulbs too.

For roadways/highways High Pressure Sodium, the higher lumens would be better for safer driving and nobody cares about the color on a freeway. For city areas such as downtown, Metal Halide, the higher lumens and crisp white color is perfect for this. For residential/rural areas coated or clear Mercury Vapor, the extreme long life and soothing color makes it ideal for these areas and really enhances the greens of landscapes. For industrial, Low Pressure Sodium where very poor color rendering is not a factor

Nothing like the beautiful cool white light of a coated Mercury Vapor lamp and the soothing hum of it's magnetic ballast.

But someone posted a study (I believe in either the MV ban thread or the MH ban thread) that found braking distances and reaction times were far less with white light.

No surprise, as with the ability to distinguish colors, the color tone difference between an obstacle and surroundings might attract driver's attention without the need of the eye focusing at it.
There is other aspect: Road sign design (at least the Vienna convention style, used outside USA) count for color vision and their readability is poor under yellow only light - my experience from travels to Belgium, where LPS are still very popular on highways, i thing the LPS is the worst light source except straight sections without any crossings - where are usually no signs...

Florescent. My first, and probably only True Lighting Love. I can remember being about 10 and going on a family vacation to Canada when I saw my first florescent streetlight...

MV comes in a close second, though...

I like coated ceramic metal halide for most urban/suburban areas(regular MH for higher wattages), HPS for areas prone to blowing snow, fog or other high accident risk areas such as curves and crosswalks. I like to see coated MV for overhead highway sign floodlights since they are both low maintenance and attenuate the green colour of our highway signs. I like MV for most rural areas too because of low maintenance.

HID lighting is the best!!!


Re: favorite lamp type « Reply #28 on: June 02, 2023, 11:29:31 PM » Author: Robotjulep
I don't really know about this one. I really like coated Mercury Vapor  :a_mv: in floodlights because they have less glare but I like HPS :a_son-t: in cobraheads  :hpscobrahd: especially 400w and 1kw ones because they are extremely bright and the light is relaxing. But I don't like LED streetlights!  :eoled:  :ledcobra: It has invaded most of my area in its ugly form. Most of the HPS or MV cobraheads in the wild are gone and the  400w HPS Holophane Mongooses are next to go. Instead of wasting money on replacing all HID luminaires with LED crap from China, the government should try and spend that money on improving their power grids so efficiency isn't a problem. Even the LED streetlights are still ran on coal power plants and aren't really much more efficient than HPS. But just replacing cobraheads that were made in USA and decorated streets with entirely new fixtures that are eyesores is stupid and wasteful. They could at least retrofit them with coated LED filament lamps (if there is such a thing.) It is just boring driving down a street filled with spoons mounted on poles. I am not saying I hate LED entirely, The a19 LED lamps are useful but LED shouldn't be mandated in cities for streetlighting.

In the order of preference 

3000K CMH
3000K LED (With good CRI and mandatory glare control! Not the eye-piercing bare boards with LEDs!)

Other sorts of MH
Good old color corrected mercury. Soothing light in a park at night. Sorry, imprinted on this as a child)
Fluorescent and induction (rare today)

Sorry, I hate orange HPS light... Also deeply hate any streetlight with more than 4000K color temp.
