Can one use 20W fluorescent tube lamps as a substitute to 40W lamps?
Posted by Bonsai Care on Feb 17, 2009
I paid for the second hand, mini object bed to means the couple of bonsai trees, this winter, indoor. The object bed has the set up in counterbalance to energy 6X40W fluorescent lamps, to illustrate the 240W complement (220V~50Hz). Unfortunately the UV-lamps do not evacuate the most appropriate spectrum indispensable for civilised world as well as growth. The lamps we need to reinstate the UV-lamps with, has to be 590mm in length, though the top wattage, accessible in this length is 20W. we devise to keep 2 of the UV lamps in the system. we wish to know if we am starting to blow the 20W lamps by we replacing the aged 40W lamps. If so, why?
Yes they will work if they fit the fixture…. They will usually pull the twenty watts they need to operate, so No, we will not blow the 20W lamps….
Ensure however which the lamps we will be regulating have been rated for 220 volt operation… we am guessing we have been in Europe given we referred to the 220V ~50Hz so which shouldn't be the problem.

If you are going from 40Watts down to 20 Watts, you'll be fine. It's bulbs that have a higher wattage than is recommended for your lamp that start blowing things up and setting things on fire.
