Check out nano-reef.com I think it's a bit cheaper to do 70W. You can find the ballast on ebay for around $50 usd. The only 150W ballast I find are around $100 usd. However I think the bulb prices are pretty similar. For the 150W, you also have to buy an extra socket if you are planning to retrofit a regent pendent because the socket on those do not fit the 150W bulbs. |
