Re: Upgrade Lamps???? 35 sucks. Put in a better lamp than a sig plus. The sig plus has the uv-b but only average in uv-a. SigHP,Supra,9k90's all have booming A and can be used alone or in the case of 9k's...mixed with higher uv-b lamps like phillips 808s or Heraeus 23's. Supras have enough B on their own. |
