Im thinking of switching to 2x250se from 2x400w se to help with heat and $$$.i need to replace the bulbs and w/ summer here my wife can get me the ballast's needed.
Im also thinking of running t5's instead of MH but like the look of MH and the shimmer.
ppl's opinion would be nice on witch way to go.
thanks

Save yourself some $$$ and keep the 400 watt ballasts. You don't need to replace it. You can drive a 250 watt bulb with a with a 400 watt ballast and still only pull 250 watts. The bulb dictates how much watts you will be pulling. I recently switched to a 250 watt radium from a 400 and still use the same 400 watt ballast. You just can't do it the other way around.

Sure alot of them will fire like that.

But, isn't that a tad rough on the bulbs lifespan?

Switch to T5's, enjoy your new found coloration and buy some powerbrite LED strips or make your own to get the shimmer you think you will miss.

Do the calculation on the energy savings, it's like 4 bucks a month per bulb at my energy rates. Unless you already have the 250w ballasts you wouldn't see a savings for years to come.

+1 on the no money saved. it would take yrs to recapture the $ spent for bulbs AND/OR ballast.

comp fans from the shak and some aluminum from home depot will fix your heat issues. bout 40 bucks TOTAL. can also run them w your temp mode depending on your/type controller. on when you hit 80 off when you hit 76. less precipitation that way.

and yes your 400 will drive 250 bulbs, no sweat. actually overdrive them so it will be nice and crisp. shorten your life span a little but no idea how much. will prob add up to the 4 bucks lost on time loss with your bulbs vs the 4 on electricity. save your loot.

I use two 4 fan Azoo units for my heat issues. Looks like they went up in price from when I bought them but they work excellent. I have them come up with the lights and an extra hour after.

thanks everyone,sorry about the late reply.As for cost on the ballast's im getting them for free.My wife will get them from her supplier,she's works for a electrical contractor.I also need to replace the bulbs its been a year on there life.the only 2 problems ive had is that 1 of my Hamilton ballast stopped working so it was replaced by a reef optics electronic so the color spectrum is a little off,but not much.The mag ballast is a hint more purple and not so crisp.
And the other problem im having is that i love the color of my 400w Heilio's and have use them for many years.I want to find the same spectrum/color of light i have now.I heard that the 250w heilio's are not the same.

Has anyone ever used one of these(^) for aquatic use?My wife ordered 2 of them for me.Its a electronic HID dimmable ballast for 320-400 watt pulse start MH lamps.
I plan on running a 250w se bulb,but am not sure what will look good.Im probably going to run a 14k bulb w/ t5 actenic.I

I do have a web site but do not know how to post a link.

To post a link, you can simply copy and paste the web address.

T5 would solve your heating issues. But whether the cost would be worth it to you or not is up to you.

A good t5 upgrade is expensive. Also, it's good to have knowledge about what bulbs are good, and which are not going to give you the results you want to achieve.

If you follow Sonny's thread to the end, you will see the transition in color that the T5 lighting has helped him achieve.

I wasn't doubting the savings overall... I was justifying your purchase by saying that the savings will be greater than 4 dollars on your electric bill. The last I heard, is electricity is really expensive in California because they have high rates. Correct me if I am wrong.

Way to much thats why im downgrading.sorry i miss understood you.you were talking about me living in cali.He pays $4 a month each bulb.LOL.My bill is in the highest pay tier and it 21 cent a KWH.wife figured it about $45 just to run the 2x400's:( a month.

What do ppl think of the SE Hamilton14k 250w bulb?

if you go with t5 try out the ATI PM otherwise ATI makes a little cheaper sunpower module but it gives out great PAR nontheless

I grew up in OC and paid their horrible rates until 2 years ago :) I fluctuate between 12 and 14 cents a kwh now.
