Metal Halide Lamp Question...

[WABlonde]

Looking to replace the lamps for the tank.... 150W 10K double ended metal halides. I've purchased them in the past from Marine Depot. Shamefully, it's been a loooong time, the corals are doing poorly and we're having an algae outbreak. *Note: We're wanting out of our aquarium, so don't want to spend a lot of $$ at the moment.

Looking around and I found these...http://www.topbulb.com/mh150-td-ndl-150w-t7-metal-halide-double-end

Question...
What are these? Why are they so cheap and do they work for tanks? I don't have much on the coral side but do have anemones that I'd like to thrive.

Thanks in advance.

First off it's a 4200K bulb, you need a bulb at LEAST in the 5500K range to work for the anemones. It is probably a chinese made bulb. Most people don't like the quality of them and they tend to burn out faster. I found this one http://www.amazon.com/gp/product/B00RQPP92Q/ref=pd_lpo_sbs_dp_ss_1/191-4919108-2903715?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=lpo-top-stripe-1&pf_rd_r=168K5SJ9F3AXD9YF1ZSR&pf_rd_t=201&pf_rd_p=1944687602&pf_rd_i=B007X6458C
It should do the job for you and is still inexpensive.
