Home Made Mh Unit

Also, quite a few manufacturers offer 12,000K bulbs. These are a nice go between from the 10 to 14k

See now that is something I dislike about Australia. We don't get squat in the way of variation in many things including lights.
We have 4,500K triphosphors
6,500K daylights
10,000, 14,000K & 20,000K and that's it. It would be nice to go to a shop and be able to at least order other items besides the very basics. Bloody third world country I live in

That's the downside to living in the sixth largest country by land mass and with a population about 1/3 that of the UK. Too few people and too large an area to cover.

Heh... try living in the second largest with the same amount.

20,000K would go the opposite from blue towards what looks like the yellow end of the spectrum, .

appologies for my quote here this should be the other way round from yellow to blue

however the colour saturation may be so great blue is not visible to the eye (different typf light makes cones and rods in your eyes behave differently such as SOX and SON which are typical in commercial lighting shouldnt be mixed for highway lighting purposes), also a number of factors could affect the output like the reflector, running temp and age of lamp to name a few.

Personally i would change the lamp to a 10000k lamp and see if your happier

And being honest it will make little difference where it comes from or who makes it as if its is specified as 10000 deg Kelvin thats what it will have to be, the only thing that may sway me to a particular manufacturere is the specified burning hours and %performance loss over a given time.

and Colin_T there must be a reputable lighting dealer that deals with MH, if it were me id go to the who ever maintains the street lighting in your area and speak to them as i'm fairly sure they will have contacts in the right places that they may be able to give you. you never know it could pay.

Found this a while back and it gives a nice visual representation of what some different bulbs and bulb combos will look like.

I rang our power company to ask for info about street lights but they refused to give me any info claiming I wasn't authorised to receive any info about them. What a joke It was a nice idea but our power company is still in the dark ages. We still have wooden power poles that break during winter storms and black out entire neighbourhoods. We have wires that snap and spark around in your back yard when council verge trees drop branches on them. We have magpies (birds) that sometimes preen each other while standing on different wires, BANG. No more magpie and no more power.

The government claims it is too expensive to change all the power to underground so instead they spend millions each year pruning trees that are too close to them, washing down the wires and terminals to prevent fires from starting, (not that it makes much difference because a couple of people died a few years ago when a pole fire started a major bush fire that killed them). And they spend millions fixing poles and wires after cars hit them and bring them down onto the roads and houses. Nope, underground power is just too expensive to consider. They do put it in new areas but aren't going to bother with established areas.

I might have to go and buy some from the internet. Anyone speak Japanese or German?

For showjyr
there are some pretty interesting coloured lights coming from that website. Not sure I like them all myself. It's bizarre they have so many to choose from and all the same kelvin rating.

 

[showjyr]

What do you mean all the same kelvin rating? They have 5000K, 6500K, 10000K, 12000K, 15000K, and 20000K.....I just don't see a 14000K.

what I mean is that irregardless where the lamp comes from or who makes it if the lamp is rated at say 12000k 150w then it will be the same as any other lamp rated at the same K and wattage

Sorry jeasko, I was replying to the end of Colin_T's post.


Not true though, a lamp rated at 12000K(or any other) of say 150w(or any other) will not always look the same. The lamps manufactured by different companies even rated the same will generally have different colors and hues.

as far as I was aware the kelvin will determin the colour therefore if its rated at 10000k doesnt matter who makes it ti should be the same colour, but guess some cheap ones are less accurate and may not be 10000k even though they state they are
