confirmation on a sales strategum I would hazard.
Overt advertising is out but discussion, debate Q&A and endorsement is fine if balanced.
OK, why are LED's better than fluorescents for chickens then?
What sort of LED? GaAlAs on GaAs, isoelectronically doped GaP, GaN Quantum wells on sapphire + cerium and YAG phosphors, Blue GaInN quantum wells with just YAG phosphor? Phosphor-on-chip or remote phoshor?
What illumination level is optimum (Iin whatever units you prefer)?
Is it better to have small individual inverters for each LED cluster, or a few larger constant current supplies?
What is the efficiency of the inverters or power supplies being proposed, what is their power factor, and is it leading or lagging?
What is the predicted wearout life of the LEDs?
What is the predicted random failure rate of the LEDs in FITs? (Failures in 10-to-the-power-9 hours)?
What is the random failure rate of the inverters in FITs a) with the lamp fitting upright
b) with the lamp fitting inverted.
Will the units tolerate a 100 microsecond 700 volt domestic mains switching transient?
Better stop before perfectly legitimate forum users start to lose the will to live!
