Here are some of my pet peeves in lighting-
> LED lighting having dead chips, flickering (people with epilepsy will hate this especially) and purpling too quickly
.
> In a pair of tubes, the NOS one is fragile and breaks easily and broken while the EOL or gassed one is strong.
> Lamps without ballasts; I like collecting HID and fluorescent lamps but the lack of availability of ballasts makes them useless.
> Seeing lamps that I want, be very common elsewhere (I still do not have any white 3500k or cool white 4000k-4500k TL (only 2x pl lamps in 840 and 640 colour), while they are throwaway lamps in areas like US and UK).
> Lack of information on some etches. All I am asking for is wattage and colour yet some brands STILL can't provide atleast these basic specs.
> Lamps without sleeve or box. Especially incandescents with weird shape.
> Standardized boxes so I can stack them.
> Lamps with terrible lifespan. I am looking at you, halogen.
> Shopkeepers being indirect. "Do you have any non LED lamps?" "No". Then later while asking for LEDs they show their stash of non led lamps.
> Standardized lamp sizes. Especially short TLs and CFLs.
> Seeing lamps I would like, rotting away and abandoned, especially specialty TLs and neon signs.
> Date codes. I am lucky that Indian brands mostly use direct numbers.
As I am more of a lamp guy than a fixture guy, I would like some attention to lamps being standard.
Update- here are some incidents elaborating further on point #2 (some similar)
1) In a 2x pl 11w fixture, the NOS one hit the ballast while removing and broke while the one with heavy use got out perfectly.
2) In two 5w pl lamps, the one with almost no use had a badly scratched tube and etch while the used one (deep darkening) has a shiny new etch and clean tube
