New 400w MH installation at aquarium shop

New 400w MH installation at aquarium shop

Click to view full size image

For whatever reason the "hobby" markets (indoor horticulture, aquariums) seems to still prefer HID over LED. The staff at this store were in the process of installing a HUGE aquarium, and they had two of these lights installed above it. Looks like they're using Plusrite Blue/20,000K lamps.

I spoke to the shop owner for a while, he kept referring to the lights as "HQI" and not metal halide. Ive seen this before, interestingly the entire aquarium market loosely refers to all metal halide lamps as "HQI" regardless if they were manufactured by Osram or not. He said the live coral requires intense sunlight-like lighting with a strong blue spectrum for coral growth.

Looks like there's an Actinic-03 on somewhere in the back

Interesting because here its becoming all about LED...MH & Fluorescent are a dieing breed.
(I'm old-fashioned, I'll be sticking with fluorescent for my aquariums (atleast those with live plants)
Same goes for the houseplants - fluorescent.

I haven't heard that before .. its either 'metal halide' or HID that I've heard.

I've read a lot about the fact that in the American aquarium market, the term "HQI", is used as a generic name for a metal halide lamp, especially the high kelvin ones, and in particular, the RX7s double ended ones, like the ones I've in my track light at my room at my hostel.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

BlueHalide - I guess "HQI" is a general shorthand for metal halide lamps used among aquarium installers and users, exactly like "MBI" is used in England, or "iodures" is in France. Each group of people mildly/weakly knowledgeable in lighting technologies have a popular way of designating certain type of lamps... same goes for "bulbs" instead of "lamps".

Greater technology should not mean lesser beauty!

I looked at some videos about aquarium lighting a while back and I think the reason people prefer MH is because they are much more of a point source than LEDs or Fluorescents. This means higher penetration (more cd/lm), a higher contrast of light and dark, and that nice looking shimmer, which many people find looks more attractive than when a tank is lit more diffusely with the other 2 aforementioned sources.

HID in aquariums would simulate full sun whereas high output fluorescent is more diffuse and simulates a slight cloud cover.

I have considered aquarium lights for my living room to simulate summer sun on dark winter days.

I think part of the reason why metal halides are more popular on aquariums than LED is because it's point-source light and they are usually simple and easy to maintain (my local fish shop actually uses ballast boxes from MH highbays connected to reflectors like that). I just hope this is one application where HID doesn't loose out to LED.

Any machine is a smoke machine if you operate it wrong enough.
