I care for animals

I care for the environment :

 - It takes huge resources to raise animals (land area to grow food for them, water for the crops and for the animal's direct consumption) over the length of their lifetime in the industry. All that to make a product out of it once at the end of this period. It is many times more efficient to just grow crops for ourselves

 - The breathing and farting of farm animals accounts for a triangle of its own in the pie chart of greenhouse gases emissions caused by humans. (by humans because we are the ones who grow the animals in such huge quantities)



"Well great to hear, in Israel do you guys have companies that make meat substitutes from soy like MorningStar or Boca?"

We have. But i dont eat any of that. I just eat vegetables/fruits/.... for what they are, or things made out of them. Dont need any specially made meat "retrofits"

Where can I find 250 watt MV black light bulbs? I have an idea for a black light street light.

Why are you guys vegan if I might ask?
I'm actually vegetarian, but the reason we are vegan/vegetarian is this: we either care for animals or health reasons, you'll understand if you've ever seen an animal get slaughtered.

I am vegan

Well great to hear, in Israel do you guys have companies that make meat substitutes from soy like MorningStar or Boca?

These are free shipping to the USA, while no shipping is offered for Canada NOR contact possible!

Can you buy the 2 remaining Zarlog, get them free shipping to you, and then ship them to me?

I'll pay you $40 for the 2 remaining plus all the shipping and packing you incur? Do it! Then PM me!
Yes, if they are still available this afternoon I can probably do that.  Smiley

In addition :

The Ceramic arctube allows the use of Halides which would damage the original Quartz arc tube, making wider choice available

The types of Halides used are no longer unique to the US or Europe. Many of the more advanced lamp types are available for all countries

True. The first MH lamps, had plain MV arctubes (With the starting resistor), but shorter, and had mercury and metal halide salts to improve the color rendering and lumen efficacy. Modern MH lamps, have different arctube designs without the starting resistor, and requires an ignitor similar to the high pressure sodium lamps. Today, there are also metal halide lamps with ceramic arctubes, that allow increasing the temperature of the metal halide salts and improving color rendering and lumen efficacy.
The american developed metal halide lamps with mercury, sodium and scandium iodides. The european favorited the tri-salt with mercury and indium, thallium and sodium iodides. Osram favorited with mercury and dysprosium and thallium.

This is a fascinating fixture possibly from before the turn of the 20th century as Solanaceae mentions. If the lamps still on this are from that period they would be a gold-mine for clues...

After the initial successes with incandescent and arc-lamps at around 1880-1900, it was uncertain if electricity would displace illuminating gas. Mantled gas-light was flourishing in this period. The first electric power systems for incandescent lighting used direct current (DC) generators with DC light bulbs. These early systems often had power disruptions and voltage drops; The voltage in DC power wires steadily declined with increasing distance and power plants needed to be close to the lamps they served.

Many "upscale" houses were constructed with dual services (gas and electric) in that period. If you can remove - very carefully - a few of the lamps and take a picture or two post it here. Also look closely at the base of the lamps for any markings. The lamps might be 100volt DC lamps.
