View Full Version : 175 watt metal halide bulbs - fiction?

I have a Odyssea MH / PC hood, 2006 model, and I'm happy with it. I've had it a year and ZERO problems for a year now.

I'm trying to replace the HQI bulbs, and they're listed as 175w HQI on the hood. In looking for replacements, I can only find them listed in one site online, and the actual picture of the bulb and box says "150w HQI". And they're out of stock. And they're suspiciously listed as $25. huh?

Seriously... These "175 watt" bulbs are nowhere.

I've read some comments saying that 175's don't exist, and Odyssea is just mislabeling 150w bulbs as 175w.

2 Questions:

1) Does anybody know if 150's will work in this Odyssea fixture?
Anyone doing it now?

2) I hear that the older models have had fire problems. IF the ballasts are indeed rated for (real) 175's, and people are putting 150's in there, that would explain the fires, IMO. no reports on the 2006 models; as I said, I've had no problems with this product other than finding replacement bulbs.

I'm hoping I can replace these with some Phoenix 14k HQI's.

Thanks,

G.

sorry - my 2nd question is:
Wouldn't I blow up 150w bulbs if the MH hood is really rated at 175w?

Yeah, from what I understand the 175w is only available as a SE bulb.

That's the only question i can answer, though. :)

I believe the bulbs should say the wattage on them - check those first. HQI will either be 150 watts or 250. 250s are bigger and you can probably figure it out by checking the size

From what I understand the ballast can either run a double ended 150 watt or SE 175 watt, I have not found any bulb that is really a double ended 175 watt... Double ended come in 70, 150, 250, 400 and a 100 watt on an M91

Odyssea uses 150 watt double end hqi 175 watts only come in single end. Dont buy the odyssea bulbs to replace the old ones. Look into coral life, current, or some other good brand.

don't look into coral life they are very cheap and low output bulbs. for 150 de bulbs try the radium or phoenix 14k bulbs for good output and decent color.

cool. Somebody can confirm that 175 watt HQI (double-ended) metal halides don't exist. Can I get a second? anyone else know for sure?

I'd hate to put 150w bulbs into a 175w hood, have them burn up and explode, and set my house on fire. That would definitley ruin my week

I have worked in the industry for 16 years and I have never heard of a 175 HQI single ended bulb. There could be a 175 HQI ballast, butt not bulb. You should only be able to fit a 150 DE bulb in that fixture. i like the Reeflux bulbs by coralvue. Affordable and a good color output.
Good luck

what I have are HQI bulbs, double-ended. That part is not arguable. BUT the Odyssea company is claiming they're 175w. I doubt it, and it sounds like they're really 150's.

Thanks to everyone for helping out.

WAKESETTER - you can confirm, with your experience, that there's no double-ended 175w bulbs? thanks.

while you are on the line with them, order some reeflux bulbs.

175w DE bulbs don't exist, at least I have never seen them.

look them up as coralvue. They have two grades of bulbs. Reeflux is the better bulb.
