Obviuosly the "tech" is closer related to cfl than T5's which don't Quote:
ALL tubes require ballasts.. Technically they should all be as efficient.. but they are not.. Guess as soon as you bend a tube it loses efficiency (speculation). If you know why they should be different I'm all ears.. guess one can push to 100l/w https://assets2.sylvania.com/media/img/asset-2234714 Again, just started this for reference.. Crappy t5 ballasts woudn't get 100l/watt either.. but you are correct, mostly referring to self ballasted lamps.. https://assets2.sylvania.com/media/img/asset-2062200 Last edited by oreo57; 05/25/2018 at 11:01 AM. |

You do realize we are two led users arguing about lamps on a MH versus LED thread? Have a great and enjoyable weekend. It is going to be 100 Degrees in South Texas this weekend and next week. I will probably turn my LEDS down from 10 hours to 8, because summer is here.

I wanted to post this a few weeks ago after lightfair but went on vacation and was busy before and after.
Well a few things. Lightfair is mostly new fixtures. A few things learned there. One I would guess over 90 percent of the fixtures shown were led. About 25 to 30 percent of the booths was cheap Chinese fixtures and their booths were empty.. No one is going to spec them because it is our blank if something goes wrong. With how expensive a booth is it seems like a waste of money for them. We also spec fixtures from a reliable rep who handles problems. Another thing I learned is the leap in technology for spreading out led s with diffusers or indirect and what they can do for the price of a LED fixture. The reef hobby lighting is so far behind and ripping people off in price. . I mean Radions just started using a diffuser. The prices are stupid high for a cheap plastic fixture. Even though 90 percent of the fixtures displayed were led when you looked up what did you see? Metal halide and HPS and the place is probably lit by over a thousand. My point is halides is going to be carried for a while when you still have HPS which never caught on to begin with because of the ugly yellow. I spend allot of time looking up at lights because of my job. Also by the end of the day you are smashed because they lure you into booths with free drinks. Thankfully we took a bus. Not anything to do lightfair but was talking to my LFS this weekend and they sell everything including high end. I was talking about ordering me a t-5 fixture and He told me led sales have slowed and there seems to be a swing back to halide and t-5. Believe me he is on top of everything too. He has people coming to him even from out of state because he carries allot of stuff you cant get at a lfs and competitive with internet prices. He also can order and carries hard to get fish. He carries everything from Radion, Kessil, AI to cheap Chinese fixtures. Just a straight up good guy too. Never seen a place with such loyal customers.

This data shows web based interest towards MHs, LEDs and T5s in Fish & Aquaria related topics.
https://trends.google.com/trends/exp...0halide,LED,T5 It shows since ~june 2010, LEDs have a clear lead over MH, and since November 2011 over T5. Globally, data also shows interest towards each lighting system for regions and countries. It shows it both as total (first map), as well as, break down of each system (remaining maps). There is no country where MHs have the majority of interest. Highest interest for MHs is in New Zealand and US where it is 27% and 26%. Still in both cases, it is lowest compared to LEDs or T5s. There are few contures where T5s are more popular than LEDs, these include Isreal, Hungary, Singapore, Malaysia, Philippines, etc. Rest are all LED.

What is this based on ? Searches? If so I would think people would search more for newer technology. Not much to learn about t-5 or halides that is not known. Not surprising at all Even though I do not run led right now I read more about led because that is whats changing.

That search is kind of silly. 2004? This thread started in 2012 when some people started noticing it wasn't easy to grow some corals under LED.

And it shows the trend of MH dominant, to a mix MH-T5 and then to a mix of T5-LED and finally to LED dominant pretty accurately. |

The point is, besides early interest the trends since 2012 have been surprisingly flat. I know when I got started in 2012 I was all LED, then I had horrible luck with SPS and shading and but figured it was my water or fixtures so I stayed LED for a while and dumped a lot of money into BML strips to solve shading issues but colors on some of my SPS still looked liek crap. Finally got fed up and put some Aquaticlife T5 fixtures over my 40 breeder. When my luck suddenly changed I was told I fixed my water issues and it had nothing to do with the light. This was, a couple of months after the switch. 1 month later. These pictures were taken in 2014, which is why I picked the date. This was around the same time the 'something is wrong with LED' discussion started in earnest. I know I searched for T5 at the time. So why have the aquarium trends for lighting been generally flat since 2014? There is no good answer other than google trends is useless for this IMO, unless you want to suggest that MH use is no longer falling, or if it is falling the rate is extremely slow.

After 2012, if you remove LEDs and T5s, you can see it is not flat but still droping very slowly. If you have LEDs on the graph, it makes the scale to large to see that. Assuming number people entering into the hobby is increasing, staying same or slowly droping still indicates overall usage share is dropping more than that. Overall I agree that MH use is no longer falling (or falling at a very low rate), but its market share is getting smaller. Total number of people who use MHs is probably the same compared to 5 years ago, but number of people in this hobby is a lot larger compared to 5 years ago. Over the years, with the given order, I used MHs, MH-T5 combo, LEDs and now I use LED-T5 combo. For me the LED-T5 combo gave the best results. |

I think a better trend to watch is the pricing of long lasting LED lighting solutions that can produce the same brightness as some of the high wattage halide fixtures. Right now I think it's a simple cost equation. Replacing all the halides with LED in some of the bigger installations still doesn't make good cost sense. I do agree that once that point is reached then halide users might have a problem, either that or they get used to paying a lot more for bulbs. We T5 users have a long and bright future so far, IMO. For me, bulbs are cheaper now than they were 6 years ago when I was buying 6700K for freshwater.

There are/were metal halide used in freshwater plant tanks.

Are we talking about a reef tank or plant tank regarding the PAR value.

Since the PAR necessary for fw tanks is "relatively" low in comparison to sw needs, MH's just won't survive well except as a "specialty look". Granted the same LED vs everyone else is still even present in fw discussions. That "victory" will generally be easier.. LOL.. Terrestrial plants, fw aquatic plants, sw photosynthetic organisms.. many similarities, many differences.. Last edited by oreo57; 06/09/2018 at 05:55 PM. |

Corals react to light different from plants.
Light under water is refracted. Use what ever light GIVES YOU. The results YOU want. It may not be what someone else wants.

Indeed. Lighting is more a preference these days. All major led fixtures on the market have more than enough PAR for coral. Sent from my iPhone using Tapatalk |

i have used VHO, T5, MH, and multiple LED. I am running a ORPHEK V4 now on a RSM E260 and it is the best I have seen.

hang as many AC flashlights over your tank and see what the outcome is.

ok. Back to the more serious discussion... the V4 ORPHEK is the best single lighting system i have tried hands downs. Just trying to help...
