was the bulb it replaced 6500k? you will tend to find the higher the 'k' rating the brighter they look. it does not affect performance.

I was at the green machine today. And ironically we had a discussion about this. They reckon after 1ft of depth they are pretty useless. In fact, they were in the process of ripping some out and replacing them with halides...

I got 4 slimline led strips designed for a car from maplins for 15 quid. Cut the cable and wired them to a 12v plug they are self adhedsive so ive modified my light unit and installed them.

from my knowledge it should do, and i can understand where your coming from. i dont really want to go down to one bulb either but if it reduces the algae........ removing the reflecters will reduce the intensity if its easy enough to do. my personal opinion if you dont want to remove a bulb is...

personally i have 2 of my 4 t5 lights on for 6 hours and they are at least 15" above the waterline. ive started to get algae now so im serverly debating taking it down to the 1 bulb...

is that the one with the 2 MH bulbs and two t5s? if your planning a very high tech setup id say go for it as you can always remove bulbs and raise the unit until your tank is established. that way when and if you do want more light its available for you. Although i cant justify ever having a...

I'd think if its a tri star cree it would definatly work. Not too sure if it was just the normal cree.....

ahhhhhh haha so far ive done it everyday as of yet no luck. altho considering theres only usually uptp 40 a day sharing the chances aint bad....

just to let you know on their facebook page (tankscape) they have a picture of it, if you share and like there is a chance you can win it! (today only, prize will change tomorrow)

wow, now they look smart!

no experience with grobeam but theres at least 20 cree led's on that build which is more than enough, if there tri star bulbs triple that, but there doesnt seem to be much info. however they also appear to be dimmable looking at the pics do thats a bonus. throw into account it has the moonlight...

I cant really comment without seeing it, (is there a link) but before I knew properly about planted tanks I built my own cree led light unit before realising it was incredably overpowered. How many bulbs are on the unit? And does it say if they are tri star or not? And is there the option of a...

Was a post about fake rolexs and stuff im presuming, the same post was duplicated on near enough every post. Some form of spam....

.....you say your using co2? have you moved the drop checker round the tank to see if everywhere good? if the flow isn't just right you could get dead spots. Also what is the problem with the plants? are they actually dying, or is it just poor growth? if you make sure those perimeters are good...

depends what the lighting unit is, but most people D.I.Y it.

I dont think it matters personally. I have not got one myself but I would imagine the closer you can get it to the filter the better, so the bubbles have longer to diffuse before they enter your tank the up atomiser seems to be everyones choice on here. From reading other posts it appears it...

http://www.ebay.co.uk/sch/i.html?_nkw=l ... &_from=R40 Ebay would be your best bet? but may i ask what you plan on using them for as they will not be sufficient for lighting most aquariums......

cheers! just what i needed to hear :)

anyone know if just over 2wpg of t5 will be good enough then?

hi, im new to large tanks and i have acquired a 200l aquarium. im planning to do a high tech amazon theme with co2. would this lighting be enough? Silver T5 Aquarium Light 120cm Measurements: 120 X 18 X 6 cm Fits up to 123cm length tanks Power: 108W (2 X 54W) i make that out as just over...
