Question 1

Would these be any good as lighting for photography?

Accepted Answer

Dear Customer:
  Thanks for asking
  This LED bulb is very bright,but if it's used for photography we need to confirm with below details:
  1.This one has a small fan build-in,so there would be a low humming sound during operation,if it's for video-graphy the humming sound will maybe influence
  2.Photography asks for high CRI to get the nature color,which is normally beyond 92,yet this one is labelled with 85.It's very good for household or commercial area lighting,but maybe still not efficient for photographer.
  So we suggest you to get some professional equipment for photography to get the best performance.
  Hope my answer helps
  Thank you

Question 3

I want to replace the 70w elliptical sodium bulb in an outdoor fitting with a 50w led one , is it the same size in length and width as a 70w son bulb?

Accepted Answer

I can only offer some approximate dimensions of the bayonet fitting version that I purchased;  The total length is 181mm, comprising the COB envelope at 105mm, the base collar at 30mm + 10mm as it tapers sharply to the bayonet fitting of 36mm max.. Respective widths are;  47mm, 50mm and 30mm max. The base collar could be a bit of a pig depending on any existing shrouding on what is presumably an Edison fitting in your case. Another possible concern is that this unit has an internal ducted fan so needs adequate space around it to dissipate heat. Good Luck; Simon.

Question 4

I bought 5 of these lamps and they have a five-year warranty. The lamp does not work well. How can I replace it with another one?

Accepted Answer

Contact the Seller via Amazon.  In the unlikely event that this fails to secure a replacement, contact Amazon themselves.  I'm sure you'll secure satisfaction one way or the other.  In my case I had a 50w corn-bulb which only lasted a few months before it failed and that was replaced all-but-instantly.  All my other corn-bulbs are doing fine, but note that poor air circulation around the bulb definitely shortens their lives, while no air circulation at all (i.e. within a sealed globe) is quickly catastrophic.
