I'd go with DX for the improved color rendition in the event the customer doesn't have an obvious preference for clear, especially for a light being used in the front of a house.

Back in the day, yardblasters, which were usually expected to be mounted higher up, were supplied with clear lamps.  Tallpacks, and smaller fixtures that maybe located lower and closer to a door, were supplied with coated/DX lamps.

Hello—

I have someone who purchased one of my Chinese Philips H39KB-175/DXs. Asking about what lamp would be best for their yard light (asking me if I could send him whatever variant would work best). From what he described, the light is on the front of his house nearby the front door.

Should I send a coated or clear bulb? If clear, I plan to send an ED-28 H39KB-175 and if coated I have the choice between a US-made (2002) and Chinese-made (2012) lamp. What do you guys think?

Understandable, @Ash . I have already gone through the rock phase (Muse, Radiohead, Evancescence, etc...) as well as the R&B phase (Akon, Timbaland, Mariah, etc...).

So I fully understand your transition away. It seems to be a "temporary" fixation until I find the next thing that scratches my itch. But I will always come back in time and relisten, and still enjoy what were once my "favorite" genres.

When I was younger, I really enjoyed Synthwave. Since I have all of those tracks downloaded to my phone, I usually queue them up when flying or traveling through regions with poor or nonexistent cell service.

I used to be mainly into it in my teens, back then it was not available for streaming (and i prefer an offline collection over streaming anyway), it was GB's of single tracks and complete sessions on the hard drive

Of tracks i liked at different times, which can be found on Youtube :

And this does not represent yet what is in full trance sessions you may find

I still appreciate it, but moved to other things including Rock (the likes of Evancescence/Nightwish) and Synthwave

I am an avid fan of club music / trance. Some of my favorites are:

In and Out of Love — Armin Van Buuren
'There's a Stranger in My House' — Tamia (Hex Hector Club Mix)
'I Turn to You' — Melanie C (Hex Hector Radio Edit)
Here I Go Again — E-Type
Something (Extended) — Lasgo
4th Rendezvous — Jean Michel Jarre
Let Go — Paul van Dyk
Tuvan — Armin Van Buuren


Etc.

I also listen to other types of music, but I will say it's my favorite. Any others like me here?

Line AC voltage is connected to series circuit of 12uF capacitor, ballast, lamp

Lets assume that if we succeed to start the lamp, it can then keep going in this circuit with leading power factor

An initial pulse for starting the lamp can be made by short circuiting parallel to the lamp, you can try it with an ordinary on/off switch manually. Switch it on for <1 sec and immediately off

The rest of the circuit is supplying 141V DC to a relay (probably with 110V DC or 220V DC coil), which will switch it on and keep it switched on permanently as long as the circuit is powered

This means that in the beginning the relay contact is closed, and it disconnects when the relay is turned on. The connected relay contacts are C and NC (11 and 12 for typical DIN relay)

The 2nd capacitor is there to try to limit sparking in the relay contacts



The problems with this circuit :

Lamp starting by high voltage pulse can sometimes not work. The starter must check if the lamp works, if no then try again. All starting circuits do it : Fluorescent starter (if the fluorescent lamp is not working, the glow lamp will light again), HPS ignitor (it checks the voltage), and so on

This circuit does not. If the lamp did not start in the 1st time, or if it was interrupted by a power blink, it will remain off, and you will have to switch it off and on again

There is no delay in the operation of the relay. If your switch has bad connection or contact jitter, the voltage at turn on will rise slowly. At some moment the voltage may be sufficient to switch the relay, but not sufficient to keep the arc in the lamp, the lamp won't start

The voltage supplied to the relay in this circuit (with 100V AC in) is 141V DC. The closest relay coil ratings i know are 110V DC and 220V DC. For 110V DC, this may be a little high (the relay may overheat over extended use). For 220V DC, 141V may or may not suffice to switch the relay at all

Here also three phase residential services are common, most houses since 70's usually getting it, basic electrical service power is around 17kW (3x25A) limited usually by a power limiter like MCB without short circuit electromagnetic interruptor in some cases or standard type C MCBs talking about modern meter cabinets, but residential can get also 3x40A service or higher 3x50 which gives around 30kW.
But some apartments in apartment blocks still works on single phase, usually max 25A (older ones)

This is a diagram drawn by my online friend, and he actually got it to work! Does anyone know how it works?
