Ushio 400w

[Charlie Davidson]

I have been told by a few people, that ushio 400w bulbs will fire on M-59 400w ballast. Has anyone here used ushio 400w standard mag ballast?
I have a ushio 175, it needs the extra "starter" in the pulse start ballast. (luckly I have one) it will not fire on my probe start 175.
Great looking bulb's
I want to replace my XM20ks with ushio 14ks..

Try calling someone like HelloLights, they should know the real deal.

Josh, I have tried premium aquatics. They did not answer yet. but someone in canada replied with single word.. Yes. A trusted friend told me he believed it would be fine, but was not %100 sure. (I will call hellolights)

BTW, Thanks, really like the color. Guess they do not make a 250w 14k?

Adrian at Hello lights said 175w needs a pulse start ballast.
the 400w needs probe start.. Guess I will be ordering 2!

Not so fast...

According to Ushios website the north american 400w 10k does require the standard M59 like I orginally thought, but it appears they recommend the pulse start M135 for the 14k's.

Whats the difference between these two 400W 10k bulbs?

This pulse start vs. probe start stuff is confusing, especially when companies like Ushio seem to have bulbs of each type.

Charlie, see if HelloLights will guarantee the bulbs will fire on your ballast and allow you to return them if they don't.

I believe the CWA is a north american version with a built in ignitor designed to be run on M59 probe start ballasts. From all the specs listed on the website, that appears to be the only difference.

Brandon, Thanks.. Seems I forgot its just as easy to look for website! DUH.....

[Charlie Davidson]

Dang I can not find it! DUH.. Duh...
