What are the best bulbs in combination ?
I can choose 2 of these bulbs (all 55W PC) 1. Freshwater Tropical - 50% white 7100K / 50% pink 8000K 2. Freshwater Plant - 50% blue 12000K / 50% pink 8000K 3. Daylight - 7100K I'm thinking 1&2. But - I may not get any as there are some T5 lights specially designed to fit in the Juwel tanks coming out soon.... |
I would go with 1 & 3.
|
I would go with 1&1.
|
Another vote for 1 & 3.

No-one thinks bulb 2 should be used ?? The Plant bulb ??
|
No, 12000K is not a typically used value for plant bulbs.
|
Looks like it will be 1&3 then. Any other views ?

I chose 2 & 3 1 & 2 will be too pinky, a plant bulb and full spec light would be good (2&3) I suspect 1 & 3 would be ok aswell, but not my first choice. Also the plant bulb at the front daylight at the back. |

They will be available in the following sizes and will be a direct profile replacement for existing T8 lighting units. The units will be supplied with ATI Aqua Blue Special lamps and their Super Reflectors which are at least 10% brighter than any standard aluminum version and incorporate easy to replace reflective strips. ATI T5 Retro Fit Juwel Light Unit 2 x 24w 800mm ATI T5 Retro Fit Juwel Light Unit 2 x 39w 1000mm ATI T5 Retro Fit Juwel Light Unit 2 x 54w 1200mm ATI T5 Retro Fit Juwel Light Unit 2 x 54w 1500mm ..and they are apparently available from this week...but they're not - I checked. ---------------------------------------------------------------------------------- I decided not to go for the Juwel units as I still can't get enough light from them. As for the poll, it seems so close I think I'll go for 2 & 3. I think it would be silly not to choose the plant specific bulb to provide the long (red) and short (blue) wavelengths that are req'd for photosynthesis. I agree that 1&2 will be too pink. Any reasons why this is the wrong choice ? |
