Title: 9000 hours?
Post by: steve771 on October 22, 2004, 04:55:17 pm

I have a DelOzone unit in my spa.  Their site says it is rated for 9000 hours.  It is only active when my filtration kicks in (1-4 times per day, and then for an hour each time).  Even at 4 times per day X 1 hour=4 hours per day that it is "on" equals a lifetime of over 6 years!

That seems a bit high for any bulb, doesn't it?  ???

Actually, every time it turns on, the surge it takes to turn on eats up 4 hours of life.


sooooooooo, if it turns on 4 times a day, for an hour each time, you're going through 20 hours of lif a day. ..... making for a relitive life of about 1-1/2 years

Which model do you have? If it's the Eclipse model, then you have a CD unit with a small chamber. The chamber is visible right on the front of the unit. Looks like this:

Nope, mine is a lot narrower.  It is a UV unit.  Thanks Dr. Spa for the info on the bulb life.  Another question... when would one know when the bulb is no longer working?  Would you go strictly by time, or is there another way?

Time. The bulb may very well be lit but not creating enough ozone to matter.

Thanks Chas.  Hey, just a thought... I've heard that CD is more efficient than UV.  When the bulb life goes on this unit, could I just swap out the unit for a CD one?  Or could that cause problems?  ???

What is the life of the chip on the CD ozone? would be my frist question.

Second what type of spa is it that you are putting it in?

In my opinion if it does not have enough contact time to water you may just be eating your cover faster then the UV bulb do to the amount of ozone off gas.

Well, the life of the chip on the Del Eclipse is also 9000 hours. I don't think there are any penalties for the start-up surge though - frankly I'm not sure about that one.

The chip costs about $40 to $50 and is easily replaced by most DIY, so yes - you should have no trouble upgrading to a CD unit when your UV unit is done.

The cost of the Eclipse varies wildly: from a low of $125 up to $250. The unit comes with a variety of cords, so be sure to order the correct unit for use with your equipment.
