![]() Yep.
![]() I see Iwasaki has a 14k DE now in the 250W size. I might try that for my ritteri tank (250W DE over that one). Currently using a Ushio 14k on that one.

![]() Yep, but I just brought the fixture back out to restart my in-wall tank. I was going to sell it...

![]() You guys think they are as bright as the higher "K", [14& up], single ended 250 bulbs?

![]() Unfortunately I don't really have any way to objectively quantify that. To the naked eye it's a bright, crisp-white colour. It is one of the nicest "white" lamps I've ever used. For brightness, I'd say it's easily comparable to an Ushio on a proper ballast - but unlike an Ushio, it is a probe start lamp, so runs, and starts, perfectly on my M57 ballasts.

![]() Actually, the answer is a quantifiable "yes" when they are run on an electronic ballast according to Sanjay's results.

![]() I have just tried the 175w Iwasakis today and I have to say they are amazingly bright and this from someone who has been using 10k xms (the xms were going on 2 years old though
![]() Some pics ![]() ![]() Still not as nice a colour as vhos but better then any other MHs I've tried but they have only had a few hours burn in time hopefully it will get even better. Now I wish I had gone for the Iwasaki 250w DEs as well Last edited by marie; 01-16-2008 at 03:30 AM. |

![]() My 45g, 24in. H cube requires a halide. Its all sps corals.
After reading all info I can find on the 175w Iwasaki, I think thats what I,m going to use w/ an electronic ballast. The par readings are higher than any of the usual 250wSE 12K or 14K I have used in the past. Also I have been long time Iwasaki fan, using both the 250w & 400w 65K,s over many different tanks. The 250,s mentioned, although a nice colour, just dont seem to cut it in par. I suppose one could use a higher par 250 bulb, such as 10K or some of the DE bulbs. I still would use electronic on that and not HQI. Whatcha think? ![]()

![]() I need to get some new bulbs. I'm on the wait list for them at Premium Aquatics, just wondered if there is someplace else that stocks them?
I see they are called 15k now. |
