Just for the record, the shoplights I got from walmart are quiet enough
that I never hear them... certainly quieter than my ultra-silent eheim
2215 canister filter. The ones I got were between $7 and $8 each for a
dual-bulb 40 inch fixture... maybe the price was $7.32? If someones
interested in the specific make, I can check next time I'm there.
