The HTG hps bulbs don't have a great color temperature. About 4100K.

Look into the GE Lucalox LU400 bulb. The price ranges from $13 online to $29 in most local shops.

The put out 51k Lumens initially and about 45k at half life. What's really interesting is the color temperature which 2100K. Very orange/red bulb. Great for flowering.
daihashi Reviewed by daihashi on . cheapo HPS Going to need a new HPS bulb and im kinda low on fundage. I did couple searches, but didn't find to much on using sylvania bulbs from Lows. I seen one there for 20 bux and thats right in my $$ range. I had decent dence buds with my old HPS bulb(bought the setup on craigslist) But I noticed my yield was sub-par compared to the one I did with 1 70 watt hps(brand new, non horti) and 6 cfls. I'd like to just get a new bulb for it, so I can rule that out as a problem. Can I get good yields Rating: 5
