Best overhead light bulb to use?
I’ve been using this 2 foot aquarium light in my fixture above, is there anything better I could switch it with? https://www.farmandfleet.com/products/0 ... gK6pfD_BwE

I don't use artificial light for cacti and know the daily duration needed so no doubt others who do will advise, but there is an article on this on Cactiguide:-

20 w wasn’t suggested and was said to be very weak. But my outlet can only handle 20 w so I guess I have no choice.

Both these articles are useful, up to a point, but LED technology is now much better than it was only a few years ago, so is now a very good (and arguably the best) option.DaveW wrote: ↑Sat Sep 19, 2020 10:00 am I don't use artificial light for cacti and know the daily duration needed so no doubt others who do will advise, but there is an article on this on Cactiguide:-

I've just bought some 20W, 2400 lumens LED batten lights in the UK https://www.google.com/search?q=20W%2C+ ... ten+lights, with side reflectors I'd expect they will be OK for about a 1ft x 2ft 6" area of seedlings or, with with a narrower reflector set up, a 2ft line of more mature plants. The light will need to be close to the top of the plants. Light intensity diminishes quickly with increased distance from the source.keithp2012 wrote: ↑Sat Sep 26, 2020 3:38 am 20 w wasn’t suggested and was said to be very weak.

Re: Best overhead light bulb to use?
LEDs give more light per watt, so if you're limited to only 20 watts that would be your best option.
