Hey everyone,

I have recently built a small 10.6inch LCD PJ and well, I need a lamp for it

I am very interested in the 150w caramic as used by elken2004 and others, the CDM-TD 150W /942 RX7S, or G12 base.

I am from England and yes a lamp newbie . I have found the CDM-TD150-942 and the G12 version of this lamp (CDM-T150-942) on this website.

It seems like a good website, and I would like to order from them, or some somewhere in the UK BUT I don't know exactly what I need to get it working .

I have found some philips 150w Philips Metal Halide Ballasts here they sell two which are 150w, im not sure the difference or which one I want.

Apart from the ballast is there anything else I need to get it fired up? an ignorer or something?

If someone can let me know, and maybe check out that site i would be hugely grateful!

Thanks so much everyone one

EDIT: I just noticed the two ballast say something about Ignitor and capacitor, so does this mean it includes one? and IS all I need?

One says Ignitor: SU20S, Capacitor: Uf. 18, the other says Ignitor: SN58, Capacitor Uf. 18.

Ma2T,

Ballastwise.com has electronic ballast for the CDM.

There is a Mag ballast that I bought, let me find the link, its at home on my favorites and im at work.

If you are interested in the Osram powerball, Camis has both the G12 (HCI-T) and RX7S (HCI-TS) versions here. They are located just over ½ way down the webpage.

Cheers Johnzo, but I would rather get it from that site I mentioned or a UK site.

I did find the "Philips 150w CDMT Electronic Ballast" which is meant to be specifically for the CDM lamps. But it's £90 / $180.

Mag is cool for me, save me some cash

Nice find senior_technician, I think I would rather go for the Philips ceramic rather than the powerball, but it's a close 2nd.

Would the powerball need the same ballast as the CDM?, and is it JUST the ballast I need or other stuff also?

Cheers

Wow! They actually ship to Canada from the UK. Too bad they charge a ridiculous £55.00 for shipping.

Can anyone tell me if the 150w ballast I pointed out is all I need? OR is there something else I need?

Thanks

It sounds like one of those would work (includes cap/igniter...don't get an 'ignorer' or it won't fire-up...<g>). {And whatever you do, don't ask a 'deciderer' to help!]
Show them this...printed out:
http://www.solaballast.com/pdf/E-871-WDD-117.pdf
'Which one' is the question (I see no detail-page/spec's there...the bulb needs 207w/1.8A. Can you ask someone working there?
You'll need a base...unless you get 2-ender and fudge with yours (and I still don't know why you don't make your's 'right'/exchange?).

Cheers Hap, so I guess all i need is one of those ballast and the lamp, which is good. But which one, humz, I will try and find a data sheet for them. I only found the electronic ballasts on philips' site :/.

Im thinking about going with the two ender, or getting a base. If your talking about my HID, thats because the seller is not very responsive to my questions, but much I can do.

I have found the data sheet on a site for the two 150w mag ballasts I can get.

http://www.lampgustaf.se/butik/Assets/pdf_.../7023/7023s.pdf

There specs for the BSN 150 L307TS and the BSN 150 L407ITS are on the 4th page. The L407 is "semi-paralell IMP" and the L307 is "superimposed SIP", what ever that means.

Without PF correction (whatever that is lol) they are both 1.8 amps, with PF correction max 1.2 and norm 0.85 amps.

Both have a cap of 18/250μF/V. While the L407 has a cable Cap of 1.0μF/V and the L307 a cable cap of 0.1μF/V, and slightly different losses.

I think the main difference is the cable cap. which im not sure what that is. So I guess either of these should be okay? But which one to order? Maybe the 307 as that has a higher cable cap?

Thanks

I simply can't tell...but I would NOT think 'both' (big diff betwixt 1.0 and 0.1!).
[If/when ignitors 'kick on', as they do when over-dimmed, they burn-up]
Any way I can just send you a ballast from here...and avoid custom/VAT (call it 'gift' or something)?

I have found some info on the ceramic lamps from the philips data sheet.

Lamp info 93 volts, 1.85 amps. Min ignition voltage 3.5Kv.

3) Data supplied on conventional ballast. Improved ratings on electronic ballasts.
4) Data for 35W 4200K is based on operation from an electronic ballast. Lamps can run on conventional ballasts with a small reduction in performance.

A horizontally operated ConstantColor™ CMH lamp, such as a Double-Ended type, will also produce noticeably less flicker.

Interesting to me is that they say a suitable ignitor is the "SU20S" which is mentioned in the L307 ballast.

Cheers for the offer in sending Hap, much appreciated , if i'm not sure enough about a ballast I can find here I might take you up on that offer

I think I will go for it and order the L307, I have been trying to work this out for a week now :/.

If it does not work, I have an email from they saying it should be okay, so if not I should be able to get a refund okay.

Speak up now if this is wrong lol.

Well I ordered it, thanks for the help everyone.

I just hope no one now says its wrong!

Looks like my ballast will be here tomorrow, but no lamp yet :/, typical.

If you're looking for this stuff in Canada, then this post may help you.

Well I have the ballast, they seem to have sent the 407 by mistake but I think it's okay.

I am still confused wether this is all I need or if I need an igniter / capacitor also, I don't know if it is built in etc.

Also, there were no instructions included regarding wiring, and I can't find anything on the net either.

There is a photo of it below, I don't know which terminals to connect to the mains power and which ends to the lamp base. How the hell am I meant to find out? :/

Thanks for your help everyone. I am tempted to paypal someone $20 if they can get my lamp working lol.

that is only the ballast, you still need the ignitor and cap,,

the diagram on ballast shows the four screw points that are on the right hand side, and where they connect to..

if you take a better pic of diagram, would make it easier to be accurate..

Elken, you know of a good Magnetic ballast that will ship here to U.S.A, <$70...

For the CDM-TD 150w.

Thanks Elken, I thought as much after I recived it, I must admit im very confused and I very much appreciate your help.

I thought it came with a capacitor / igniter as listed on the specs page where I bought it from it says the igniter and cap info, I thought it was included or built in, but I guess they are listing what needs to be gotten?, kind of misleading.

Also, the site mentions SN58 as the ignitor, they don't seem to sell that, but they sell the ballat and the lamps......


Here is a close up of the diagram, I don't understand which screw points they relate to.

Edit: I found this wiring diag on philips site, it ask for a semi parallel igniter.

Many thanks

Hey Mordeth,

I found this Mag Ballast for $42.00 bucks. http://www.1000bulbs.com/product.php?product=2547

I've been considering it. It's a M142 Sola Basic.

Spec.s are here. http://www.1000bulbs.com/images/PDF/solaEM...1_specsheet.pdf

Regards,

Movie Freak

I've seen some like that, but I thought it had to be 1.8 amps. If that will work without issues, i'm all for it.

do you need both the cap and ignitor for the ceramic light? i thought it was mainly the pulse start that needed both.

also have you picked a bulb yet?

As far as i know:
Electronic System = All-in-one box
Magnetic System = Coil/Core Ballast + Ignitor + Capacitor.

ceramic lamps are a type of pulse start lamp (ie. they use an outside source [ignitor] to generate the "pulse" to start the lamp); so yes, ceramics will need an ignitor as well as a cap. as ozstang has pointed out, this is for magnetic type ballasts... electronic ballasts contain all the necessary circuitry in one box, no external cap or ignitor will be needed with then as the parts are contained on the internal circuit board.

cheers,
gs

Many helps for the help guys, I wish I knew this before. I was under the impression that the capacitor / igniter was included in / with the mag ballast, as like with the eletric.

Now the weekend is over I have ordered the igniter (SN58) and the 18mF capacitor.

So when these arrive I should finally have light and a finish PJ!,

....now, just how to work out how to wire it up.

To my surprise I received back and email from philips.

"I have attached a data sheet for the ballast which shows the circuit diagram, but in essence, the ballast should have 4 terminal like the picture on the front of the data sheet. Starting from the left, the first terminal is usually for a 230V supply and the second terminal is for 240V, therefore your incoming live connection should be made to the second terminal. The third is for one of the wires on the igniter and the fourth is for connection to the lamp.

Please phone me if I can be of further help."

I also uploaded the PDF here which has a wiring diagram. (as well as the photo on page 1)

If anyone can work out / tell me exactly how to wire this up I would be hugely appreciative!

Many thanks everyone

Anyone know how I can wire this up? someone much know how to hook this all up? :/

Going from what the philips guy said about the terminals and from the wiring diag, this is my laughable diag of how I think it need to be wired up. lol.

Is this correct?

Many Thanks

See the diagram on top of the ballast? Make it like that.

I can't see the two taps on the ballast that go to the lamp but one side has the 240v and 250v inputs and the other should have a L on it for lamp and the other tap might have an " I" for the igniter, so all looks OK as long as the igniter and lamp wires from the ballast are not switched.

The Igniter should have its wires labled too.

Well thanks very much guys, it worked

Yesterday I connected it all up, and there was light . I hooked it all up into my PJ and the results were very good. Thanks for your help everyone

But here is the bad news, stupid company I ordered the lamp from sent the wrong one, very similar, but different, and not ceramic.

They sent the "MHN-TD 150W/842 RX7s" http://www.prismaecat.lighting.philips.com...amp;tt=Overview

Which has the same colour temp, but slightly less lumens, 12900 instead of 14200 and a lower 84 for the colour. I used it anyhow (waiting on return information) and the results were very impressive, so I can't wait to see how the better bulb will do!... oh also the bulb im using now has a longer arc.

The Philips ballast seems good also, very low noise, it's hard to hear with no covering, and when inside the PJ I can't hear it at all.

I seen this bulb first time. Maybe it's kind of old product, but arc size looks very small to me (photo analyze sucks lol). What is the arc size in the reality ?

Seems about just under 2cm. Or about 2x the size of the ceramic I wanted. I am hoping they will send me the lamp next day delivery (thats what I paid for) and then I will send the other lamp back, I don't want any down time.

Well, we want it small . It's about 11mm I think, in the ceramics.

Thanks for the replies... I think it was a daydream .
