For under canopies the "Light Strip xxxxx" series by "dinorius_redundicus" are good .... no lamp (but you may not see this is missing) just the light pool; which you set just above the platform surface. Worth a try anyway.
Strange, I got them off the DLS last year. They are build version 2.0 so should be OK for you. Might be the DLS ftp playing up again, it was broken the other day. If you still can't get them after another try or two send me your email in a pm and I'll send them as a cdp (if you want).
