is this good in a delta E-20?
garry g on Jun 3, 2019
how many hours should this last ?
A shopper on Nov 16, 2017
BEST ANSWER: That depends on who you ask. I've had my uv sanitizer for a long time now and used to change the bulb every season as recommended by the dealer. When I bought my last bulb, over a year ago, the person who sold it to me told me it wasn't necessary to change them annually if they still worked. I put the new bulb in but kept the old one for a spare. All I can tell you is it still lights. I leave my pump running 24/7 all summer and the uv is on the whole time, so you can do the math. The pool is open from the middle of April until late October.
Which ballast matches this?

BEST ANSWER: I am not sure I understand your question but I was able to use the replacement lamp for my Delta UV D-80.
How long is the UV bulb?? is it 35 1/8" long
A shopper on Aug 3, 2020
BEST ANSWER: The bulb is 35 1/8" long if you include the electrical contact pins in the overall length. If you don't include the length of the pins, the lamp is 34 7/8" long. Hope this is helpful.
what is the replacement uv bulb and quartz tube for delta d 40 uv system?
A shopper on Jun 8, 2019
BEST ANSWER: This is for an Ultraviolet sanitation system for your pool. The bulb is what does the work of sanitation. The quartz tube is what the bulb is housed in, which is also placed in the UV canister. I use this system in addition to my salt chlorinator.

I purchased this replacement and while the ballast light is green there is no visible light. The original light was visible at night. This one is not. Is this normal?

rebuilding a Delta ES20
This lamp is the said replacement for the original lamp however it is shorter and fatter than the original. The original -o- ring is to small and when streched does not seal and lets the bulb free fall to the bottom of the quartz tube. I sourced a larger -o- ring and it held the lamp correctly...works fine.
