MH question: 175 DE = 275 lamp mount???

ilovetrains · 04/13/2007, 07:52 PM

Today, a LFS told me I could use a canopy with 175 watt metal halide double ended bulbs instead of 250 watt because the 175 double end were just as bright as 250 lamp mount.

Is this true??

no, but some 175w bulbs have the same par as some 250w bulbs,

Do you guys know what the brand would be in the Coral Life 72 inch fixture? LFS looks to have a very good price on the 72 inch fixture, but it uses PC not T5. I like the fixture, and of course they have it set-up on a display tank and it appears to put out plenty for all the critters inside, which is more than we will ever have in our tank.
