metal halide lights for uv and heat

One major question I guess that needs to be asked her is is there a plan of using a double ended metal halide bulb or a single end mogal screw in style

Mogal socket bulbs come with an already uv protective glass on surrounded the gas element so very little uv passes through I've been personally along with a couple others at the university have been testing the iwasaki 6500k, 250w and 400w we are also testing the GE 6,000k
We have not concluded on results yet but when we do I'll post it up with graphs results and writes up on each should be within a week or so!
Now on to the Double Ended metal halide bulbs these come as a bare bulb with no uv protective glass so the bulb is burned between a reflector and a uv protective piece of glass that reduces the amount of uv exposure without this piece of glass things become uv burned very quickly as its a full spectrum of uv radiation
this is why me and my colleague Feel this type of bulb will give us the most promise for being able to tweak the radiation output wavelengths of these types of bulbs based on the different mixtures of glass and different sand and iron elements to help block out certain wavelengths of uv radiation while allowing certain wavelengths to pass through!! So while this is all in beginning stages it is all going to be backed by lab grade equipment and resources!

But to conclude what we've seen so far the GE 6,000k 250w mogal socket metal halide bulb is showing the most promise we are also working out a deal with them to try to alter a few of the uv protective glass surrounds on the bulbs with documented chemical alterations to the glass so we can figure out what will give us the best uv output within the safe range!!
@evil like I said been at this a while Most mogal socket bulbs block out 85-98% uv radiation to be safe to sell to the general public on the other hand the double ended bulbs put out a full spectrum of uv from about 130-520 on average depending on the type of bulb so these bulb will be the ones that will be easily altered and relatively cheap because the glass used to keep the uv output in a usable wavelength will be able to be kept for up to 10 years and you'd just have to replace the bulb and it will always be at your required wavelengths ;) maybe I cleared some stuff up maybe I lost some but I hope this helps!

I would like to see test done on repti sun 5.0 and 10.0 What kind of test and graphs will you be doing?
 
@evil the graphs I believe you are seeing doesn't represent uv output but more the spectral output (visible wavelengths / color output) those are done with lux and par meters to measure the light out put very different) and to answer the other part of your question yes we are working on developing a glass that will only allow a usable range of uv radiation between 280-355
 
@whatcamo: you know that UVB is only ~290-315....the range you specified is a bit wide :)

I am well aware of the differences between visible wavelengths and UV radiation....based on the graph (if you extrapolate) there seems to be SOME UV output on the bulbs, but as you said it doesn't show the actual UV output and so there is no way to actually know without better spec info or a UVB meter.

I was merely trying to say that just because the box says "outputs UV" does not mean it is going to be outputting the appropriate type, or amount, of UVB. And there is no way to guess this without hard scientific data on it.
 
Arcadia is making some very nice small scale Metal Halides that will...

Hi all...
ooh.. I am slacking ...
I missed this thread.

Arcadia is making some very nice smaller scale UV Metal Halides that will be available in US (110v) in a month or so.

35, 50 and 75 watt.. and possibly larger.

The spectral curve of the light is way better than any incandescent bulb.... or Merc Vapor w/ tungsten filiment.

Metal halide eats mercury vapor for breakfast. word.

Cheers!
Sincerely,
Todd
 
Possibility for 250w ?? Or 150 as I already have those ballast?

I can see a 150 Halide in the sort of distant future.

I do have an overseas (asian) source that says they have them ...
but
I... or the peeps at Arcadia.... as far as I know... haven't tested one out yet.
Its tricky because bad glass and some narrow band UV B or UV C rays getting through and you are SUNK. bad bad oooooh bad... burned eyeballs.

Arcadia is working on a nice Merc Vapor as we speak too...

But that has not got a release date yet, they still are being extensivly tested.

As folks may know, mercury vapors are real "dodgy" to make good.

Its odd because they have been around so long too boot... but the composition of the glass is key. ;)

Cheers!

PS:
In the meantime I do have a FEW Zoo Med merc vapors in stock... they are "OK".
 
Yeah I'm working extensively on glass composition for double ended halide bulbs ;) do I'm guessing the bulbs you'll be bringing to the market would be mogul socket bulbs spot light style?

or yours. ;) if they are the bomb.

I am game for whatever is the best.

so have at it!
