Metal halide lamp life expectancy

On the packageing it says 3000 hrs if I remember correctly. That's about a year. I can't see any visible light difference after a year. Must I stop being so tight or can I push the lamps a little longer?

They normally have a spectral shift at the end of the life span, but no apparent drop in intensity...

hmmm if MH only lasts a year imagine how often you have to swap T5's if you're only using T5......

The norm for T5 replacements is about a year to 18 months

Maybe we should have a poll to see how long peeps are useing them and when you first notice a drop in coral growth rate or colouration.

I am about to replace my MH's which have been running for almost 6000 hours which is the quoted lamp life on the BLV box.

On a side not, does anybody have any recommedndations as to replacement bulbs. I boughht the BLV 14K's to replace an old pair of Ventures but was rather dissapointed with the colour as it was almost identical to the Venture bulbs. I am now looking for a bluer bulb.

Giessaman is a good bulb but very expensive.Saw it for like over R1000 for one 150w bulb.Which is madness IMHO.

yup, hobby bulbs are madly priced...
the 400watt metal halide bulb i got at the electrical shop is rated at 5000 hours, and cost me R280... extremely bright, nice spectrum, seems to have a long life, and definately way cheaper than hobby lights

recently did the DIY thing on the nano, got a "recessed ceiling" fitting, 150w electronic balast, 20 000K BLV 150W MH, 3m 3-core cabtyre, and plug for around R1400 from a local lighting shop here in Joburg.. all depends on how well you are with DIY projects, and how much you are willing to spend will depict the quality of the equipment..

Lamp House is very good. I got some T5's from them recently at a really good price. I know they do stock halides too.

Mtal halide life

Average life of the metal halide may differ from make to make. One cannot say in months or years. It will depend on how long the lamp burns each day. I do aggree that they loose intensity after a while. I have used a 15000k(Aquah20) and a 14000K from The Lamphouse. The 14000k is whiter, and The Lamphouse will give you the lamp much cheaper than most aquarium shops, in fact, a lot of stores in Cape Town get their stock from The lamphouse.(Montegue gardens)

I bought a dual use fitting from aurora lights. Adustable Metal Halide down light. DO NOT REMOVE THE GLASS. The ballast gear is sold seperately. The whole setup was under R1000.00
