SimplyLED.co.uk problems ; By way of contrast I bought a reasonable qty of very expensive house brand halogen replacements; ‘g’teed to be identical’ spec to originals (output, CRI and physical dimensions).
They simply are not. The specs they publish continue to be incorrect. The bulbs were 4mm longer – meaning they would not fit flush or correctly.
Response from Simplyled was *very* poor, denying all responsibility for their published specs or compliance with DSR. They failed to resolve to my satisfaction and have never refunded the items.
I since found out they use a rigged feedback system (like a few others – google the service name!).
If you know precisely what you want they may be fine, but do not rely on their best intentions. Order a single sample first!
