    This is a good review of the Chihiro with PAR readings.

    And the plus.

    Thanks for linking that. Very good reading. PAR is very good for original A-series. Upgrading to A-series plus might result in an algae farm for me

    I could get away with the standard A-series given my tank is not that wide. But I would need to invest in those stainless steel legs to help raise the lights even further.

    For you guys who have the Chihiros how is the colour in the fish tank? These are 8000k colour temperature. Does it look more blu-ish or colder? I have a 6500k bulb in my tank right now and it is quite nice in colour. More towards the warmer yellow colour. So pleasing to stare at the tank.

    They definitely are a cold light, slight blue cast I guess, my embers in my 60p look good to me, tho I have never seen them under a RGB before.

    Chihiros is a cooler light but colors seem to be rendered well; even red. Technically I suppose higher CRI.

    Overall the tank looks 'crisp'.

    With MML you can customize each led on your tube. I did that for one my tubes but ended up with far too much warm spectrum and didn't like it.

    Thanks for the replies. I am used to warm light but it's not massively out there like a 10000k colour temperature. I can get used to it.

    It would have been nice if Chihiros sold the 90cm RGB light unit.

    Also sorry nautilusly for hijacking your thread

    Apparently the 90cm RGB and A-Series Plus will be out soon, Hinterfeld post on some of the forums (even this one) and did say they are being manufactured

    That would be great. The A-series and plus are good for plant growth but this should be even better given it has the RGB colours. It won't be as powerful but decent enough for low-medium light plants.

    It looks pretty nice as a whole unit. Also has adjustable metal legs too.

    I just contacted Hinterfeld.com about the Chihiros RGB 90cm light. They do plan on bringing out the 90cm version but it is up to the manufacturer to start producing it. They haven't made a schedule yet so they haven't even started manufacturing yet.

    Regarding the 10K spectrum etc... This is a great podacst episode to understand basics of light.

    Thanks for that. Very interesting and good insight into lighting.

    Also the links below the video provide very good reading.

    She did make a point that if you can't buy the really expensive $1500 meter to accurately measure lighting .. then manufacturers should all provide this information. The good thing is Chihiros does provide most of the information on the UKAPS forum. But i do think we should all invest in that $1500 meter

    Just to let everyone know if their interested Hinterfeld.com.au has added the Chihiros A-series plus 90cm light to the website. It is priced at an incredibly high $176

    http://www.hinterfeld.com.au/store/p...t_30-60cm.html

    It's a pretty big jump in price from the 2ft and 3ft version.

    I have MML in my Aqua One Ar850 and one tube as already blown due to too much heat or moisture. The other 2 tubes i have do have moisture under the polycarbonate lense. MML tubes work extremely well for plant growth however I personally think they aren't really suitable for under hoods where no lids are present. as for finding a light that is completely sealed, i don't think you're going to find one. you would either have to encase the light or put lids on the tank.

    I did however find these. I couldn't find them in the 90cm but i was thinking you could stagger them and they are completely sealed. imagine these at the top of the water surface excellent light penetration would always run cool and the led chips that are used are decent. 2835 leds pack a punch, i have a PLL led tube on my Aqua One Aquamode 900 using the same chips and they penetrate to the bottom. the 5760 or the 5730 leds are also decent light output if you can find a light bar using these leds.


    EDIT: I just had a look at your thread. do you still have the light bar unit that came with your tank. EVO 100 if you do look into the Arcadia t5 led tubes. they are designed to run directly on the ballasts no rewiring required. may be an option as they do have waterproof sockets.

    something to think about anyways.

    Althought individual fish do not cost much, do not think of fish as cheap little expendables.

    Agree. If you use MML in your hood, make sure you ventilated using plenty of fans. Moisture and heat will kill any led fast.

    The only lights I'm aware of that can 100% do what your talking is the Juwel helialux led's designed for Juwel tanks. However both the price and the wattage output will most likely eliminate them from your possibilitys list. (The price eliminates them from most Juwel tank owners possibility list. Even Juwel will not spec them from factory instead supplying some silly led t5 tube things.)

    I can vouch these helialux units can be just left in the tank of water let alone just under a hood with no adverse effects. But unless you had a Juwel tank I cannot see a reason to consider them unless you must have a semi submersible unit.
