Luke* Posted November 17, 2006 Report Share Posted November 17, 2006 I'm using single ended 400w 6500k bulbs on my 4 foot planted. I really like it. Quote Link to comment Share on other sites More sharing options...
shiuh Posted November 18, 2006 Author Report Share Posted November 18, 2006 so how long would a bulb last until you have to replace one? Quote Link to comment Share on other sites More sharing options...
antwan Posted November 18, 2006 Report Share Posted November 18, 2006 From what I've heard, replacing the bulb per annum will suffice, but I think 6 months is better. In the bakery that I work in, we changed the MH bulbs lighting the food display, and you can certainly tell the difference. I think the old bulbs had been up for a good 18months though.

fishboi Posted November 19, 2006 Report Share Posted November 19, 2006 so how long would a bulb last until you have to replace one? different brand of bulbs have different average bulb life [its should be on the packet/box or just simply Google the product] BLV have average life of 6000Hours. Try switched on gardener they sell MH bulbs for growing plants (funny that) Or give lamp specialists or lamp brokers a call u would think so but they stock very different bulbs then what we normally use for aquariums. lamp specialist dont stock bulbs in the K we're after as its not commonly used for anything else and the ppl that do stock MH bulbs for aquarium use are normally selling to the saltys which don't really use anything under 10000K.

TM Posted November 19, 2006 Report Share Posted November 19, 2006 So you can't get 6500k bulbs?? How about osram or Sylvania. I can get them down here if you get stuck, they are pretty common. Quote Link to comment Share on other sites More sharing options...
fishboi Posted November 19, 2006 Report Share Posted November 19, 2006 So you can't get 6500k bulbs?? How about osram or Sylvania. I can get them down here if you get stuck, they are pretty common. Osram and Sylvania are the same thing. ["Osram Sylvania" is the full name] i am unaware they do 6500K DE bulbs. i only ever used 150watt so i know they only do 150 watt in warm white and neutral white 4200K. correct me if i am wrong. [i hope i am as Osram bulbs are great 10000Hour lifetime] what can u get down there? i'll be needing more in about 3 month time so any info would be great.

TM Posted November 19, 2006 Report Share Posted November 19, 2006 Yeah, they are branded a bit diff. You are after 150w de a. 150w de come in 6500k for sure. I think they call them coralstar? i will check. It is really only fish people that use bulbs with a higher k rating, that is over 6500k.

mat692 Posted November 20, 2006 Report Share Posted November 20, 2006 I got my 6400 DEs from deepblue, they do the job (get my swords pearling) but would have liked 8000K as 6400 is still a little on the YELLOW sidefor my liking (and its all about personal taste ) TM, Me 3 if you can get 8000 Quote Link to comment Share on other sites More sharing options...
TM Posted November 20, 2006 Report Share Posted November 20, 2006 Yeah no worries. I have seen and had 6500k and 10000k bulbs, but never 8000k bulbs.

shiuh Posted November 21, 2006 Author Report Share Posted November 21, 2006 just went to Rexel Lighting and ask for a 150W daylight range . they said they dont do that range, only 3200 - 4300K for 150 W series, as for other nz lighting shop as well. the only daylight range available is 250W screw in types, is this true?
