Nepenthes Nut Posted January 22, 2006 Report Share Posted January 22, 2006 I had a look around my local diy store and they had up to 60W flourescents but on the back it said that they only produced 465 lumens. What flourescent wattage is equivalent to 100 normal watts? Do i need to find a flourescent light that procuces 2000 lumens then? Quote Link to comment Share on other sites More sharing options...
Jimmie Hansen Posted January 22, 2006 Report Share Posted January 22, 2006 Try to find cool white lights. They produce a lot more lumens, more colors and less heat. Quote Link to comment Share on other sites More sharing options...
Guest Aidan Posted January 22, 2006 Report Share Posted January 22, 2006 A 20W fluourescent is equivalent to a 100W incandescent. The lumen value sounds incorrect. Looking at a 20W Osram EL lamp I just happen to have in front of me... 1200lm is quoted on the box. Quote Link to comment Share on other sites More sharing options...
Nepenthes Nut Posted January 22, 2006 Report Share Posted January 22, 2006 How can you find out if they are cool, does it say or is it just the ones that dont say warm? But aidan it was a 60W flourescent tube that said it produced 465 lumens, not an equivalent. Quote Link to comment Share on other sites More sharing options...
Tim Posted January 22, 2006 Report Share Posted January 22, 2006 It says "cool white" on the box. Quote Link to comment Share on other sites More sharing options...
Nepenthes Nut Posted January 22, 2006 Report Share Posted January 22, 2006 ok so look for a cool white flourescent light that is over 20W? Quote Link to comment Share on other sites More sharing options...
Guest Aidan Posted January 22, 2006 Report Share Posted January 22, 2006 It may have been an 11W lamp which would be a 60W equivalent, in which case 465lm would be about right. Quote Link to comment Share on other sites More sharing options...
Nepenthes Nut Posted January 22, 2006 Report Share Posted January 22, 2006 ok so I'll have to look for a flouescent saying 20w - 100w equivalent that produces 1200 lumens / above? But the one that said 465 lm was a longish flourescent tube. Quote Link to comment Share on other sites More sharing options...
Nepenthes Nut Posted January 28, 2006 Report Share Posted January 28, 2006 I have now bought an extendable lmp with a 18 W flourescent light in it producing 1100 lumens. Is this enough as a suplement (when the sun goes down) to natural light from the window? I am willing to post a pic of the stup if this would help.

Guest Aidan Posted January 28, 2006 Report Share Posted January 28, 2006 Sounds OK, Try it and see. Quote Link to comment Share on other sites More sharing options...
Nepenthes Nut Posted January 29, 2006 Report Share Posted January 29, 2006 How much light do they need in lumens? What am I loking for to show that it is working. Will It help some strange medium sized orange spots go away? Here is the pic, i have out lined the patches with the spots on them with yellow. Is this lack of light (cant be leaf burn) or a fungus?

Guest Aidan Posted January 29, 2006 Report Share Posted January 29, 2006 How much light do they need in lumens? The only way to find out is to try it and see. As for the spots, it is more likely a pathogen than light (or lack of it) that is the cause. Quote Link to comment Share on other sites More sharing options...
Jimmie Hansen Posted January 29, 2006 Report Share Posted January 29, 2006 I grow my lowlanders under 4 x 3350 lumens. I know that is much more then they need but they seem to enjoy it. Also its best to mention that its 4 floruscent tubes. So the lumens decrease a lot by every cm. Quote Link to comment Share on other sites More sharing options...
Nepenthes Nut Posted January 29, 2006 Report Share Posted January 29, 2006 Oh well i only have 1 pot containing 2 nepenthes so i hope this is enough to keep them healthy till it is warm enough to go outside. it is more likely a pathogen What sort of pathogen and what can i do to get rid of it. So far it is only on 2 of the leaves(1 on each plant) Quote Link to comment Share on other sites More sharing options...
bux Posted January 31, 2006 Report Share Posted January 31, 2006 I use fluorescent tubes which give a full spectrum and are very effective. Some like "Biolux" from Osram or solar nature from JBL work well for Neps. bux Quote Link to comment Share on other sites More sharing options...
Jimmie Hansen Posted January 31, 2006 Report Share Posted January 31, 2006 You dont need fancy lights such as Biolux or Growlux and others. Which put out the right amount of colors and costs 3 times as much as ordinary cool white tubes which is just as good as the other ones.

bux Posted January 31, 2006 Report Share Posted January 31, 2006 You can't compare biolux and gro-lux. gro-lux is not a full spectrum tube, has a poor capability (30 Lumens/watt) and a low life. Biolux=64 Lumens/watt, life=10000hours! I grow many Heliamphora under only one biolux tube and they produce natural colored pitchers. A 30w Biolux cost about 15 Euros. bux Quote Link to comment Share on other sites More sharing options...
killerplantsguy Posted February 2, 2006 Report Share Posted February 2, 2006 I don't know if they are available in the UK, but 65w "Flourex" flood lights work nicely. They use a compact fluorescent bulb with output compared to 500w "regular bulb", whatever that means. I can say they put out a decent amount of light and the price is right $20 or so for fixture complete with bulb. Good growing, KPG Quote Link to comment Share on other sites More sharing options...
