cephalotus ,question led

[fabrizio]

Goodmorning everyone,
I wanted advice to make no mistake;
I have a terrarium (measures 120x60x40) and I wanted to change lights, at the moment I have a 6400k e2700k led (two lamps per type).
I bought bulbs always led for growth.
I wanted to know where to place them to have a maximum yield (since compared you have normal LEDs have a narrower beam of light.
I wait for advice and photos from those who already have similar systems.
thank you so much Fabrizio

I dont think it will be enough. how munch Lumen does all Lamps together have? also how far is the distance between lamp and the plants?

Hello there,

I can highly recommend the Amazon low cost LED-panels.
Last week I took them to  university to measure PAR light values and could get 200 µmol/(m²s) on the purple version (440/660nm on 50w), as well as 300 µmol/(m²s) on the newer daylight version (3500K on 75w) at a distance of 20cm, which is is a pretty usual spacing for a terrarium/vivarium.
The PAR level of ~250 µmol/(m²s) isn't as high as the average daylight level, but it seems to be pretty okay for private/small commercial basis!


Kind regards
Fabian

PS: tested products
 

75W - daylight
45W - 440/660

Hi everyone, thanks for the answers.
now they are placed with lighting downwards, but areas of less light are formed (given the narrow radius of the LEDs); I wanted to wear them you have four inclined angles and back towards the center; but I wanted an opinion.
the distance from the plants is 15 / 20cm.
thank you so much Fabrizio
