Run up of my 175w probe start Metalarc on a CWA ballast is in the same range as the 1000w-1500w sports lighters....it's pretty long and drawn out. Conversely, a Philips All-Start pulse start ceramic metal halide lamp on the same ballast runs up a bit faster, though still fairly long.

A 70w Philips CMH runs up quite a bit faster than a Sylvania pulse start quartz lamp with pinch seals on an HX ballast, and a Venture spherical arc tube quartz lamp is maybe only a little faster than the Sylvania. All are faster than probe start halide on CWA.

For me, it's the same as with other lighting - it depends on where I'm using it, what I'm using it for, and the effect I'm trying to get.

I don't use many LED lights at home but I have 3000K ones in the landscape path lights (12V) and I had daylight LEDs in the garage door opener and refrigerator at my former house but this house has integrated LEDs for those appliances. I have two PAR30 5000K LEDs on a dimmer over the kitchen sink area, and most everything else is legacy lighting technologies (non LED).

Generally I use 4000K to 6500K for supplementing daylight if it's a darker, overcast day, and 3000K and below for sunset and night time. The third layer of lighting is for effects (blue, pink, blacklight, clear mercury, HPS/LPS). I generally don't run the daylight & soft white together. I have only a few oddball lights i.e. SBMV which fall in the special lighting category since they are between 3000K and 4000K.

Dang, if I decide on taking one, how would I go about paying the shipping fee?

They were completely separate, however there was some modern Westinghouse HPS lamps manufactured by Philips at Bath, NY.

It'll be a decent amount to ship it. I'd say $100+ with UPS ground. And yes, I am willing to part with both.

@Burrito Same here. About how much would it cost to ship one of those canopy lights @Maxim?

Late here, but anyhow. I guess what they done there is 2x 110V ballasts in series = 220V ballast for same lamp. For short lamps with low arc voltages like 4..6 T5 it comes out fairly close to the proper ballast value

I tried to work out the lamp arc voltage for 10W at 0.22A, i get 57V similar to an 18/20W lamp. Which sorta surprises me. I am not familiar with the 10W T8 but i expected to see lower voltage, higher current there

I like the daylight LEDs (5000K) the most, but others can have different opinions, I just like the light that the daylight LED bulbs produce.

But the 400w and 1000w HPS lamps I have seen say 8000 to 10000 hours lifespan. Are the horticulture HPS lamps different from general HPS lamps?

Circlines are sold as a set of 2 or 3 in Japan. I brought home a box of 2 in 6500K, made by Panasonic.
