I dont know if this is the right index or not? (Moderators?)

I went to Sams yesterday and they have a 5 stage under sink R/O unit with tank for $150.00.

Also, a 25w 65K PC desk light for, I think $20.00. I know Walmart sells a 25w 65K flouro bulb for around $12, but the stand on the one in Sams could be of use to DIYer's.

25w of flouro or PC converts to about 100w of NO lighting.

I dont know what the lamp efficacy is / or lumens per watt. Does anyone here know on these types of bulbs? The PC or flouro?
