I know some of you have the MH lighting from fishneedit.com

What are your impressions now that these lights have been up and running. Every review that I have seen has been when the light was first turned on.

I like the interlocking feature with the T5 HO lights as well, has anyone done this yet. The shear fact that I could get a complete lighting system with (2) 150W MH & (4) 54W T5 HO for under $450 is very tempting.

I have been using 2 of the 150W MH pendants since around January 2008 and like them very much.
Also, the bulbs they sell are very cheap but are working fine. Compared to more expensive bulbs that I use they hold their own. I've been using the 8000K 150W bulb for 6 months now, and the 10000K bulb is also nice. The 6500K bulb is too yellow, but I think that is typical for all of them. I just dont like the color. I wish I had a PAR meter to take comparative readings between my fishneedit/coralife/ADA bulbs.

I wish I could buy more of the 150W MH pendants. Last I checked, they had been unavailable for quite a while.

I know about the unavaiability, but he we site says new stock on Dec 15

Also the site has been updated to advertise the interlocking feature.

I am using their 8K bulbs and love them...

Brighter, better color... It appears to have the same "white" as the 10Ks (e-bay) I had when looking at the lights, but in addition the reds are redder and I see more yellows off the plants. (I'm trying to say, the light ain't yellower, but gives better yellows and reds - does that make sense?).

My plants are enjoying the change as well as the thread algae ;) I had an outbreak I'm just now (I hope) getting under control with the change in intensity and color (It was like "WHAM" - where did that come from???).

I've owned the 150 watt MH lights for almost a year now and it's a pretty nice unit, unlike my coralife unit it doesn't with a fan, so that's my only concern as it does get quite hot, otherwise it's fine and I just ordered another 150 watt and it should arrive today

raymond (or anybody else) - since you have an older fishneedit and now a new one: can you comment on the new ballasts? I think they changed the new units to electronic ballast. Is that correct, and what do you think about them?

Their regular price is not that much cheaper than the AM, but the sale price :faint:!!
On the blown up picture, I noticed that their reflector is smooth. My AM has sort of a cobblestone pattern. Their bulb holder is metallic? The AM has a spring loaded ceramic one. Ballast - the old AM has a German made magnetic ballast no fan. I believe the new AM ones are US made Reeflex ballast with fan. From the picture this one looks like it may be electronic? If it was encased in brushed aluminum, it would remind me of the ADA Solar I ballast.

Thanks for that detailed analysis Bunbuku. I think it's probably going to be "You get what you pay for" in terms of quality as fishneedit also sells on ebay on although has rating is all positive several members have stated that the quality of the light could be better. But given the price is the quality difference worth it. I also see there are several AM lights (i.e. Oceanlight, Spacelight) I need to contact Aqua Medic since I'm alittle confused on the actual difference.

my older fishneedit lights do have spring loaded ceramic bulb holders. As far as quality, I do have better quality MH pendants but I'm not nervous using fishneedit MH lights anymore since mine have done really well. I'll have to take a look at the reflectors - I think they may be the hammered/bumpy type but cant remember now.

the noise level is typical for a magnetic ballast, not so bad and actually quieter than the 250W ballasts I already have from another manufacturer. fishneedit says they are using electronic ballasts now and I hope someone can chime in on the quality of those.

I'd like to mention that even though their 150W MH bulbs are very cheap, I like them a lot. They hold their own against the coralife and ADA bulbs I have and at a much lower price.

I've never tried their T5 lights (bunbuku's pic), only the 150W MH pendants.

I have always wondered what the differences were between electronic and magnetic ballasts. The statement below implies that you get less light output with the electronic ballast.

Quote from AquaCave http://www.aquacave.com/150w-ocean-electronicbr-metal-halide-ballast-brby-aqua-medic-1170.html

"Ocean Electronic Ballast is an energy conscious electronic ballast that starts softly to ensure extremely long bulb life and is now standard equipment in our lighting pendants and systems (except 70w HQI and 1000w Mogul). With these new ballasts, 20K bulbs maintain a deeper and more intense blue while mid-Kelvin colors stay cooler without the small red-shift of the characteristic overdriving associated with our Ocean magnetic ballast. Subtly less intense, in terms of lumens produced, but a softer approach that appeals to those for whom blue color rendering and bulb life are primary concerns."

Bulb life is supposed to be longer (like your quote mentions) but I cant really speak to that. I dont think I've ever had an electronic ballast for MH lighting. I'm perfectly fine with magnetic ballasts for MH lighting -- I have a set of 250W ballasts that have been working for about 7 years.

I just wonder how long the new electronic fishneedit MH ballasts will run before quitting.

To answer the noise question, I will speak only about the original version of the AM 150 watt MH fixture and ballast.

I took my SPL(sound pressure level) meter :nerd: and I placed the microphone 6" from the ballast and took measurements. The SPL was 40 dB with peaks at 45 dB A-weighted. Not exactly scientific but that is the best I can do without an anechoic chamber.

According to the manual typical A weighted SPLs:

Whisper at 5ft is 32 dB
Typical residence is 48 dB; at night 42 dB
Typical large office is 58 dB
Normal speech at 1ft is 68 dB
Vacuum cleaner at 10ft is 72 dB

So unless you have the a dog's hear abilities or use the ballast as a pillow, you are unlikely to hear the hum under normal circumstances, especially if the ballast is inside you stand.

I ordered 3 of the 150w 8000k bulbs to try in my new fixture... hope it's nice.
did you order fishneedit's bulbs or some other manufacturer?

the 8000Ks they sell are pretty nice, maybe just a tad too green to my eyes. I like the 10000K, and dont care much for the looks of the 6700K, too yellow / green to me. For the price they are good bulbs. All three certainly grow plants well and hold up reasonably over time.

I have been running a coralife 10000K next to a fishneedit 8000K for a while and it does look like the coralife is brighter now, where they both started out about the same. but I can replace a fishneedit bulb 3 times for the price of one coralife. Dont even get me started on the price of ADA bulbs.
