2006 light vs. 2007 light

[compasswilting]

Is the light from last year the same as this year???

[114Klutz]

The 2007 light has 8 cold cathodes, compared to the 4 of the 06 light.

The lights are exactly the same, both have 8 tubes.

Is the HDPE the same as well? We have an old box setup already, and I don't want to take it apart to swap the diffuser...
